STFC-RAL-CR03 R61: Hello everyone, welcome to today's seminar.
STFC-RAL-CR03 R61: here in the room, I have around 10 people on Zoom.
STFC-RAL-CR03 R61: So, let us introduce our speaker. We have Xiangle Lu from University of Warwick. He earned his Bachelor of Science from Beijing, and then diplom Physica.
STFC-RAL-CR03 R61: from Hamburg.
STFC-RAL-CR03 R61: Then he completed a PhD at Heidelberg on heavy iron physics, working on data analysis in the Alice experiment at CERN. Then he moved to Oxford.
STFC-RAL-CR03 R61: as a PD…
STFC-RAL-CR03 R61: All right. Starting to work on neutrinophysics. He was awarded the Ernest Rutherford Fellowship, then joined… he joined War Week, in 2021.
STFC-RAL-CR03 R61: And… His current major project includes Juno and the Warwick TPC platform.
STFC-RAL-CR03 R61: Soap.
STFC-RAL-CR03 R61: Thank you, everyone. Hello, good morning, and hello to the people on Zoom. So, I'm glad to tell you about the status and the first research shout from the Coalition of Surf Tree.
STFC-RAL-CR03 R61: Before we talk about, you know, perhaps…
STFC-RAL-CR03 R61: is useful to reveal what's machinery. First of all, instead of what a machinery is quite poorly, it has no electric charge, and it has no marks. So, the first question is, how do we actually know there are different necinos? Six of them included. So, I call them phases machinos, actually.
STFC-RAL-CR03 R61: You know, when you turn into animals, actually, it can produce charge buckles, and then different species produce different charge.
STFC-RAL-CR03 R61: That helps. And thereby, we have…
STFC-RAL-CR03 R61: So there's a flavor assigned to the chinos, and so everything becomes a bit familiar and normal.
STFC-RAL-CR03 R61: being sent a motor. However.
STFC-RAL-CR03 R61: nature is different, slightly, so we know that neutrinos have some marks, and that actually gives us another way to recognize the neutrinos. But are they the same as the flavor way to see the neutrinos?
STFC-RAL-CR03 R61: This is the problem about, machinery identification, so to say. So the… in this animal, we have the flavor eigenstate, and then we also have now the mass eigenstate, and in fact, they are connected by the so-called PMNS matrix.
STFC-RAL-CR03 R61: Let's not go into this detail yet, but regardless, then if you don't have masses, so 3 of them, 3 different masses, what does it mean?
STFC-RAL-CR03 R61: So, one has to be the smallest, of course, and then the other has to be large. Then what is the remaining one? The remaining one really depends. If it's close to a small one, then we actually have the so-called normal ordering, and if the,
STFC-RAL-CR03 R61: To be the one that is actually close to the large one, we have the emerged ordering. So, from this narrative, the early work guys that the mass ordering, or the so-called mass hierarchy problem, is in fact.
STFC-RAL-CR03 R61: A problem when there are more than two months.
STFC-RAL-CR03 R61: This is really, interesting.
STFC-RAL-CR03 R61: What's more interesting is that now we have the mass gaps.
STFC-RAL-CR03 R61: And also, the ice state mixing.
STFC-RAL-CR03 R61: Then we actually produce machine observations. This is a very blank statement. So, in fact, we can understand this by a doctor of analogy.
STFC-RAL-CR03 R61: So, for example, in a magnetic field, spin up and spin down have different energy, and then we have this energy gap, and also the up and down state combined in different ways to produce an X and Y state. So as time goes on.
STFC-RAL-CR03 R61: the X and Y states actually oscillate.
STFC-RAL-CR03 R61: This is the same thing, mathematically, as our original solution. So, we see here that she knows how the mask gap, and also the mixing.
STFC-RAL-CR03 R61: MS, and eventually, we see the flavor will either survive or disappear, so these are the same probabilities as in the spin rotation phase. But now, the phase is a function of the mass gap at M squared, and as a function of the L over in the baseline, and the final energy.
STFC-RAL-CR03 R61: So, now… By far, we haven't really talked about specifics about the
STFC-RAL-CR03 R61: as GAAP and PMS, we're here with the native. What is more important at the moment is to ask the question whether all these three flavors participate in oxygenation or not, two or three flavors. This is an important question, because if we have just two flavors.
STFC-RAL-CR03 R61: then the constraint on the oscillation probability is so strong that there's no difference between machine oscillation and anti-machine oscillation. However, when we have three frame oscillations, this additional equal freedom actually
STFC-RAL-CR03 R61: Can allow the social path to be different between tumors and anti-tumers, and therefore lead good potential.
STFC-RAL-CR03 R61: measure the so-called CP violation in the electronics sector.
STFC-RAL-CR03 R61: So, can we…
STFC-RAL-CR03 R61: to some specifics about the mass. We know three different states, so 2 independent mass scams.
STFC-RAL-CR03 R61: And the big one is 30 times larger than the small one.
STFC-RAL-CR03 R61: And now, by definition, the small one is always the 2 minus 1, and therefore the delta M squared is always
STFC-RAL-CR03 R61: Possibly. Then, if asked, the only possibility to arrange the third step either is further beyond the 2, which is the normal hierarchy, or
STFC-RAL-CR03 R61: We note first, there is this remote here. This interchangeable in my, narrative here.
STFC-RAL-CR03 R61: Let's look into the PMLS metrics.
STFC-RAL-CR03 R61: It's a bit complicated, but in fact, we can dissect it in the following world. So the 1, 2 is missing between the mass 1 and MAS2 state, and 2, 3 is about the new cau state.
STFC-RAL-CR03 R61: Then the C213 is very interesting, because if CT13 is zero, then effectively has the proof flavor missing.
STFC-RAL-CR03 R61: And by the discussion before you guys, in such a case, we won't be able to look at CPU relations.
STFC-RAL-CR03 R61: And luckily, this delta CP is not zero, and the delta CP can be… could be, in principle, the subject.
STFC-RAL-CR03 R61: So, what is the opening question in the tumor oscillation?
STFC-RAL-CR03 R61: First of all, we won't be able to measure on certain months.
STFC-RAL-CR03 R61: with efficient oscillations. Therefore, if you want to know about electron masses, we can only know about the gaps, like the M squares.
STFC-RAL-CR03 R61: And we also want to know more how they miss the head, and they made the missing parameters needs to be better determine
STFC-RAL-CR03 R61: So, mis…
STFC-RAL-CR03 R61: all these interesting fusion topics, what can we do? Experiment? So, we have different regional sources, and here is somewhere as a function of additional energy. You see the MV and the JV here. So, around this fusion, we have solar regionals, geo-dictionals.
STFC-RAL-CR03 R61: And, of course, our acid regions, also, In the achievement.
STFC-RAL-CR03 R61: If we are concerned with machine oscillations, then we will probably first look at soil additionals, right solutions, and oscillator, and atmospheric machineryls. A very interesting fact is that for the soil originals, they are all
STFC-RAL-CR03 R61: nutrients.
STFC-RAL-CR03 R61: Of the electron flavor, and in contrast, the red one is electron antigenous.
STFC-RAL-CR03 R61: And as long as oxygenation is concerned for the silicone molecules and atmospheric neutron, we care about them beyond
STFC-RAL-CR03 R61: So, just remind ourselves that there are only two independent N-squares.
STFC-RAL-CR03 R61: and the oscillation phase is proportional to a WM squared scaled by L over E. So what happens if we put all the experiments in a diagram with the energy E and the baseline L,
STFC-RAL-CR03 R61: So, here we have the MVV and the GEV routine, and the 1km baseline, a 1,000 kilometer baseline. So we see, actually, we have one cluster.
STFC-RAL-CR03 R61: We have one cost this year for direct experiments.
STFC-RAL-CR03 R61: And the outcast of Tasota and of the February part of town.
STFC-RAL-CR03 R61: They're the two things looking in the same perspective, because they're on the same line of LOV.
STFC-RAL-CR03 R61: Therefore, let's actually pop in the same delta N squared, which is the last one, the large one, because the delta N squared is large, therefore the LORE just need to be small to show the oscillation, and this fast oscillation.
STFC-RAL-CR03 R61: But still, with the Victor, We can actually extend the baseline, and we see a lot of
STFC-RAL-CR03 R61: cluster here, and it's on a different line of the LOVE, and in fact is sensitive to the small M, right? And because the deadline is quite small, it takes more time for long distance to see oscillation, therefore it is slow.
STFC-RAL-CR03 R61: oscillation.
STFC-RAL-CR03 R61: So, also, you see four disasters have their relative strength in measuring all the parameters. Here, this was 3.
STFC-RAL-CR03 R61: Here, this has 2, 3, and there's a CP, and also here, this is 1, 2, and 0M squared are all matched out. So, this is the end of the story, isn't it?
STFC-RAL-CR03 R61: Is there anything more?
STFC-RAL-CR03 R61: So, what you see here… is the…
STFC-RAL-CR03 R61: Survival probability of the reactor anti-neutrinals as a function of the baseline.
STFC-RAL-CR03 R61: How now did the pyrene measurement using accelerated kinos to measure the snow oscillation.
STFC-RAL-CR03 R61: I'm not cut.
STFC-RAL-CR03 R61: It's really highly. It is the first time that we actually measure these so-called solar missing parameters with reactors.
STFC-RAL-CR03 R61: But you can see, because they are partnering, they didn't really sit at
STFC-RAL-CR03 R61: the advanced location. And, you know, with all this hindsight.
STFC-RAL-CR03 R61: is filled, and there's no oscillation, oscillation maximum. Here, therefore, it is extremely sensitive to this solar system.
STFC-RAL-CR03 R61: And the best focus would be
STFC-RAL-CR03 R61: Juno's measurement of this autonomous synthes, and the Juno performance that this first result you saw the space of.
STFC-RAL-CR03 R61: Of course, Arjuno is built for more.
STFC-RAL-CR03 R61: If you look more closely now, we can focus on the blue line. It is a small oscillation, maybe it's a fast one, sitting on the slow one.
STFC-RAL-CR03 R61: This is very interesting because, in fact, if you look at Oh.
STFC-RAL-CR03 R61: the flavor evolved between the electron flavor and the meal and count flavor, you see something like that.
STFC-RAL-CR03 R61: So, pure different pleasure, and they graduate.
STFC-RAL-CR03 R61: Maximum need towards… maximum conversion to the milk flavor and the top flavor.
STFC-RAL-CR03 R61: So this is at the Juno baseline. Once the
STFC-RAL-CR03 R61: She knows past the genome baseline, you've actually seen
STFC-RAL-CR03 R61: Following the large oscillation, it comes back.
STFC-RAL-CR03 R61: Back and forth, back and forth. The small widow still states.
STFC-RAL-CR03 R61: This is important because This small vehicle, Actually.
STFC-RAL-CR03 R61: is sensitive to the maximum rate. So it depends on whether it's normal holding or inverted holding.
STFC-RAL-CR03 R61: We have to shoot.
STFC-RAL-CR03 R61: And, you know, it's very ambitious, we try to measure neutral mass ordering by measuring the oscillation spectrum.
STFC-RAL-CR03 R61: So, first thing first, why do we want to measure neutrino mass audit in the first place?
STFC-RAL-CR03 R61: Well, I haven't seen my TJ colleague yet, so, but I think it is a fair statement that even if you know about, you know, math and altering, it would be extremely difficult
STFC-RAL-CR03 R61: commercial.
STFC-RAL-CR03 R61: the CP. You can imagine in a scenario that
STFC-RAL-CR03 R61: Nature is mass, is normal ordering, but that one experiment actually measured the CH in this big area, in this space, but the other experiment measured
STFC-RAL-CR03 R61: A specific theme, but a little different.
STFC-RAL-CR03 R61: I'm with SpaceX.
STFC-RAL-CR03 R61: Not to mention that At the moment, we don't know which order it is.
STFC-RAL-CR03 R61: On the other hand, in order to tell whether Latino CSMR of Iraq, we grouped on the search for the journalist.
STFC-RAL-CR03 R61: What happens if we are already?
STFC-RAL-CR03 R61: Sensitive to the mass in this region, but still haven't found anything.
STFC-RAL-CR03 R61: Then the interpretation really depends on
STFC-RAL-CR03 R61: The mass order gets inverted ordering, fine. It means there's no
STFC-RAL-CR03 R61: neutron is propagate decay, and therefore, neutrinals are derived particles. But… Yve.
STFC-RAL-CR03 R61: Fortunately or unfortunately, because it's normal holding, then it means that we just have to work much harder.
STFC-RAL-CR03 R61: to try to look for, which means the object. So mass polling matters or more.
STFC-RAL-CR03 R61: to take our strategic experiment plan as well. So, it also influenced
STFC-RAL-CR03 R61: The sum of the original mask is cosmology, and it is also a place of port.
STFC-RAL-CR03 R61: In the region of labor evolution, the super evolution of supernova evolutions.
STFC-RAL-CR03 R61: So, where's Juno? Juno is, in the south part of China.
STFC-RAL-CR03 R61: Yeah? If you zoom in, you will see that there's… 52.5 kilometers.
STFC-RAL-CR03 R61: I wait for two bigger pot plants, the Longjiangular Pork Plant.
STFC-RAL-CR03 R61: And also the types of pumps.
STFC-RAL-CR03 R61: You cannot get some, names here, Hong Kong Xie, and, Guangzhou Xie, this is my hometown. So, this whole area is the so-called Guangdong, Hong Kong, Greater Bay Area, one of the powerhouses of the Chinese economy.
STFC-RAL-CR03 R61: The Journal Corporation had more than 700 participants.
STFC-RAL-CR03 R61: And we have a very strong team in Europe, for example, and the UK work started in, officially.
STFC-RAL-CR03 R61: 2022. Actually, it was only about much earlier than that.
STFC-RAL-CR03 R61: It's a pipe, corporation. You see our collaborators?
STFC-RAL-CR03 R61: At the time to help the local farmers, but just enough time to cut these small patches, you know, cold-filled.
STFC-RAL-CR03 R61: And, we try to make wound cake, this is a special type of cake, it's the IC.
STFC-RAL-CR03 R61: Coating will take. What's the issues.
STFC-RAL-CR03 R61: So, you know, there's an underground lab, so this is the core.
STFC-RAL-CR03 R61: Yeah.
STFC-RAL-CR03 R61: 500 meters deep, we have experimental pump. Because it is in a hilly area, in fact, we have about 700 lots of work.
STFC-RAL-CR03 R61: It looks like this.
STFC-RAL-CR03 R61: Hong Skye, and here is the entrance of Grant.
STFC-RAL-CR03 R61: to the lab, and also this other entrance. So, either we take the slow terminal.
STFC-RAL-CR03 R61: So, 1,000, meters, in this very interesting, card, or actually take the leaf down section meters from the vertical shock.
STFC-RAL-CR03 R61: What you see here now is the, do not detect it.
STFC-RAL-CR03 R61: The biggest structure is the cylindrical, was attacked.
STFC-RAL-CR03 R61: It has a diameter for the fuel pump.
STFC-RAL-CR03 R61: 5 meters, and the height is 44 millimeters. And in fact, there is this particle separating two regions. The outer one is most shrink off, detected with 35 kilohms of water.
STFC-RAL-CR03 R61: So… Then the inner part, I will omitre, is the 5 kilometer of the below the Tyrax.
STFC-RAL-CR03 R61: So, the Tyvek actually sits on the stainless steel structure.
STFC-RAL-CR03 R61: So, this is the whole thing smooth structure. I'm gonna sit on it, and this structure actually holds
STFC-RAL-CR03 R61: some veto PMTs.
STFC-RAL-CR03 R61: 2000, looking outwards into the water and chunk of the path.
STFC-RAL-CR03 R61: And also, some large PMTs looking inwards towards
STFC-RAL-CR03 R61: the inner structure, and also with small PMTs. So, in Porto, we have about 18.
STFC-RAL-CR03 R61: 18,000 large PMTs, and about 26,000 small PMTs. In total, they cover
STFC-RAL-CR03 R61: 78% of the area. So, this audio coverage is a scary number.
STFC-RAL-CR03 R61: Because 78% means that.
STFC-RAL-CR03 R61: The holding structure, the same structure, only can have.
STFC-RAL-CR03 R61: mechanical, precision.
STFC-RAL-CR03 R61: better than series on the meter. If things get worse, there's no way to fit them together.
STFC-RAL-CR03 R61: It would be a disaster, but we actually manage it.
STFC-RAL-CR03 R61: So, compared to pure onion, we can see the inner… innermost part is the acrylic vessel. It has a diameter of 35.4 meters.
STFC-RAL-CR03 R61: And, inside it holds 20 kilotons, increasing connector.
STFC-RAL-CR03 R61: The centimeter, light emission tip is at around 430 nanometer. It is the, wide blue, like this.
STFC-RAL-CR03 R61: So, everything is just, on paper, right? Now, let's look at some photos.
STFC-RAL-CR03 R61: So here, all we see is the stainless steel structure, and beneath it is the part of the acrylic vessel. So, assume clean, because those, are the workers, yeah.
STFC-RAL-CR03 R61: And now, you can see, actually, the little PMTs on the semi-steel structure, and actually, look closer, you can see the back of the large PMTs really being stuck.
STFC-RAL-CR03 R61: So, now, if you look at here, this is a flexible, and then this is the supporting row.
STFC-RAL-CR03 R61: on the stainless steel structure, and you can see the large PMTs and also small PMTs.
STFC-RAL-CR03 R61: And this buffer error is actually quite large.
STFC-RAL-CR03 R61: And all it has to… 10th per hour, or 5 meters.
STFC-RAL-CR03 R61: So…
STFC-RAL-CR03 R61: The Trunload project first got approved in China in 2013, and then, Lucan 14, was victory, and so on and so forth.
STFC-RAL-CR03 R61: And the conceivable construction started in 2015.
STFC-RAL-CR03 R61: We have a great, challenge to tackle because of the underground water, and then, later.
STFC-RAL-CR03 R61: towards the decade, we were hit by COVID, and eventually the zero construction was finished, and the company continued growth.
STFC-RAL-CR03 R61: And… Then we started the detective donation.
STFC-RAL-CR03 R61: And it's how it was done.
STFC-RAL-CR03 R61: About serious effort in 30 seconds.
STFC-RAL-CR03 R61: So it's done, just another time.
STFC-RAL-CR03 R61: If you look at the status, the detectors will happen inside this 2022, then 2023, and then 4, and this is…
STFC-RAL-CR03 R61: Right before everything is finished.
STFC-RAL-CR03 R61: And here is a comparison. When we first touchdown onto the base, it looks like Star Road Death Star.
STFC-RAL-CR03 R61: That's a bit.
STFC-RAL-CR03 R61: And here… You see the happy faces, everyone?
STFC-RAL-CR03 R61: But this is not done yet. We need to clean the vessel.
STFC-RAL-CR03 R61: And actually, we use a high-pressure water gun.
STFC-RAL-CR03 R61: Where do you?
STFC-RAL-CR03 R61: It's mesmerizing, isn't it? You can look at the whole day. But,
STFC-RAL-CR03 R61: Let's continue. After it's done, we can see
STFC-RAL-CR03 R61: the vessels like this. All these fights fought.
STFC-RAL-CR03 R61: Spots are actually the joints for the supporting role.
STFC-RAL-CR03 R61: On the sphinx you structure.
STFC-RAL-CR03 R61: And do the rest of you can see behind, actually, all those PMTs.
STFC-RAL-CR03 R61: So what's…
STFC-RAL-CR03 R61: This is done, you can actually fill the whole detector and also the inside of the vessel with water.
STFC-RAL-CR03 R61: pure water, and this was sadly, on December 24th.
STFC-RAL-CR03 R61: After 2 months, the sun, it looks like it's…
STFC-RAL-CR03 R61: So, from February 2025, we start to replace the water in the present detector with nickel synthetic. It's a very delicate process.
STFC-RAL-CR03 R61: Therefore, two, six months to finish. But then, when it's finished.
STFC-RAL-CR03 R61: really move on quickly. So, in August, 115?
STFC-RAL-CR03 R61: Once the liquid center finish, filling is finished, we start the calculation campaign.
STFC-RAL-CR03 R61: And on the 26th of August, we have this completion. You can see…
STFC-RAL-CR03 R61: The initial takes when the random, freedom cancellation is high and gradually decays out.
STFC-RAL-CR03 R61: After some days, we start to connect. This is quality data.
STFC-RAL-CR03 R61: And by the time of the beginning of November, we have connected 69 calendar days of data, and this corresponds to 59.1 visas for a team.
STFC-RAL-CR03 R61: our database.
STFC-RAL-CR03 R61: But, actually, during the collaboration, campaign before the, this data starting, we actually have already received, letter decimals, and that is,
STFC-RAL-CR03 R61: Let's play for one of the golden tickets. I will talk about the original characteristic theta, but basically, you would first see a prompt, positive signal.
STFC-RAL-CR03 R61: And then nearby, you also see a delayed neutral signal.
STFC-RAL-CR03 R61: So, spatial displacement is all, 1 meter or less, and then the pump is a few hundred microns.
STFC-RAL-CR03 R61: What was it?
STFC-RAL-CR03 R61: So, one of the key performance impacts is the generation net, both for the liquid inclinator and also for the water.
STFC-RAL-CR03 R61: Because, for the, center detector, the attention length actually is critical.
STFC-RAL-CR03 R61: to tell us how much the life being will receive. And also, remember how much are critical helpful.
STFC-RAL-CR03 R61: Radius of about 18 meters.
STFC-RAL-CR03 R61: So, if the attenuation length is too low, it means that the photon might not even get to the GMPs.
STFC-RAL-CR03 R61: or part of them get to it, or not, so depends on where the event is. There could be an uniformity.
STFC-RAL-CR03 R61: of the test response. So we… Try to,
STFC-RAL-CR03 R61: achieve a very low attenuation length. So, for the central detector, the design goes 20 meters, and we have actually achieved from L to 20.6 meters at the development
STFC-RAL-CR03 R61: move now.
STFC-RAL-CR03 R61: And for the water drunk of detector, the design goal is 40 meters alternation length. But with ultra-pure water, actually, we have achieved 70 meters.
STFC-RAL-CR03 R61: the… And we actually are looking at the low energy, and therefore, radial purity is important.
STFC-RAL-CR03 R61: We have, however, internal reader activities from two major sources. First of all, it's a cosmogenic separation.
STFC-RAL-CR03 R61: When muons come into the detector and they interact, actually can produce all this variation for that. On the other hand, the material itself could contain natural liquidity.
STFC-RAL-CR03 R61: Uranium, thorium, so on and so forth. All this decay.
STFC-RAL-CR03 R61: Eventually, to our past pages.
STFC-RAL-CR03 R61: On the one hand, they are condemnish, of course. On the other hand, actually, they provide us an ideal image.
STFC-RAL-CR03 R61: separation source for AVA, for example. And specifically, if you look at this decay chain bipoles, so-called bipol 2 and 4,
STFC-RAL-CR03 R61: Here. So, this moves, and they're also blown them.
STFC-RAL-CR03 R61: Case 2…
STFC-RAL-CR03 R61: beta is a tombscope, and then alpha is basically. This has some very, nice characteristic, coincidence, and that we can identify them easily. It would be very helpful. So, by measuring the bipole.
STFC-RAL-CR03 R61: We actually have an idea.
STFC-RAL-CR03 R61: How to ensure their activities.
STFC-RAL-CR03 R61: I take inside the detector and also die south.
STFC-RAL-CR03 R61: So… Quite a ton.
STFC-RAL-CR03 R61: Well, given the commission, we actually measure
STFC-RAL-CR03 R61: all this radioactivity inside the CE, and also the water frequency. You see that all these contaminations.
STFC-RAL-CR03 R61: Either is already achieved the design level, or even faster than the design.
STFC-RAL-CR03 R61: The effort is actually tremendous. The analogy would be to achieve all this is equivalent to have less than 10 milligrams of gas in the whole time field we go into it.
STFC-RAL-CR03 R61: It's many orders of magnitude.
STFC-RAL-CR03 R61: of control. So… Fortunately, the energy resolution is very important, therefore we actually need to calibrate a Worldwide.
STFC-RAL-CR03 R61: This is our city, and we can actually deploy the source around the Z-axis, and also we can put the source
STFC-RAL-CR03 R61: Radiative source, division source, or a smooth tank here, all around the muscle itself.
STFC-RAL-CR03 R61: This is the exact deployment plan.
STFC-RAL-CR03 R61: So, we have the C-level 7 mechanism, VT4.
STFC-RAL-CR03 R61: potassium 40, and cobalt 60. They all have different gamuts, they have different advantages.
STFC-RAL-CR03 R61: axis.
STFC-RAL-CR03 R61: And we also have dimension carbon source that give us the strong gamma signal, and also the neutron capture gamma signals.
STFC-RAL-CR03 R61: And they are deployed on the Z-axis, and also on this CRS system.
STFC-RAL-CR03 R61: Bye.
STFC-RAL-CR03 R61: So… with all this, Energy, Jim, back of
STFC-RAL-CR03 R61: We actually can understand the nonlinearity.
STFC-RAL-CR03 R61: Of the energy spokes. You know, our different…
STFC-RAL-CR03 R61: In fact, our understanding is better than 1%.
STFC-RAL-CR03 R61: If you look at our rejected energy, Compared to the expected one.
STFC-RAL-CR03 R61: We have achieved an understanding of all, and you scale better than 0.5%.
STFC-RAL-CR03 R61: And if you look at this, at the different location of the radius, maybe when the event happens at different radius, then we see, actually.
STFC-RAL-CR03 R61: They don't vary that much. It's a good indication of the uniformity.
STFC-RAL-CR03 R61: And of course, when things happen near the boundary of the vessel, this becomes
STFC-RAL-CR03 R61: were difficult to come to, this neighborhood. So… inside folk.
STFC-RAL-CR03 R61: of the judicial warning. Actually, the formality is kind of cheap.
STFC-RAL-CR03 R61: So… Coming to the energy calibration, the eventual assessment study, did we use the romantic power source.
STFC-RAL-CR03 R61: And look at the energy restriction. There's 40%?
STFC-RAL-CR03 R61: However, if we look at all this gamma archival, which is close to 1md, He,
STFC-RAL-CR03 R61: The solution is 3.4%. You might say, okay, it's good enough, but in fact, it's still, worse than, the expectation, or 3.1%. But remember that.
STFC-RAL-CR03 R61: It's only 60 days, or… data. And we are still trying to control through construction, and with,
STFC-RAL-CR03 R61: Better methods, and also better energy consumption.
STFC-RAL-CR03 R61: So, the timing of the art event is…
STFC-RAL-CR03 R61: Very useful for two reasons. First is to reject backgrounds, and also, the information is used in the spatial, reconstruction, maybe the vertex reconstruction.
STFC-RAL-CR03 R61: So what you can, see in this slide is that the event level distribution time may be the, actual measured time compared to the expected, time for the event.
STFC-RAL-CR03 R61: looks like this for the how much PMT, and also the Chinese GMT. For both of them.
STFC-RAL-CR03 R61: you see the prompt arrival peak, and also the data is well described by the model. So this is very important because it means that we understand the time response of our PMTs, and this is consistent with the design, and it's not a limiting fact.
STFC-RAL-CR03 R61: So, all this performance is sufficient for background visual and also for the with extra construction.
STFC-RAL-CR03 R61: So, the spatial reconstruction is that we use the time information and also potentially with the energy information to reconstruct where it's happening inside this, all simulation.
STFC-RAL-CR03 R61: So, we put the German source along the Z axis, and then you can drop the Z component of the vertex, and we can see the bias is within 10 centimeters.
STFC-RAL-CR03 R61: This is… And, the deviation is not just at the boundary.
STFC-RAL-CR03 R61: And on the other hand, the resolution of this reconstruction is using 10 to 10 to 20 centimeters. So you see, actually, in both cases, the boundary effect is very strong. On the one hand, the knife reaction is not uniform, and it's sometimes maxed.
STFC-RAL-CR03 R61: And also, when you're close to the boundary, the total refraction actually happens, and then change the optical properties very much. Therefore, the boundary is always a difficult region.
STFC-RAL-CR03 R61: And, yeah, we have many information to tell from this project. First of all.
STFC-RAL-CR03 R61: This shows the event rate at the outermost 10 centimeters.
STFC-RAL-CR03 R61: inside a critical vessel. So, what you see is that you can adjust the position of the environment.
STFC-RAL-CR03 R61: And you see all these bright spots.
STFC-RAL-CR03 R61: They are actually the external radioactivity, coming from the John forms of clingo.
STFC-RAL-CR03 R61: So, we see that in the outer part of a critic vessel, actually, there's regularity because of the external radioactivity. Reason 1. Reason 2 is that in all this breathing, the
STFC-RAL-CR03 R61: optical performance, It's way back, and for this region, we actually need to cut out
STFC-RAL-CR03 R61: Yeah, very, out of the, electric world.
STFC-RAL-CR03 R61: But overall, the white execute injunction is sufficient for mass selection.
STFC-RAL-CR03 R61: Like, to define the physician wording, and also, if you want to correct for any
STFC-RAL-CR03 R61: Morningsteps, or radio debts.
STFC-RAL-CR03 R61: non-uniformity, then the word congestion will be used.
STFC-RAL-CR03 R61: Now, let's look at the physical event. What happens if an anti-imeter?
STFC-RAL-CR03 R61: Which, you know, comes steam inside the detector. So…
STFC-RAL-CR03 R61: We'll be looking at so-called numerous fated check. It's a reaction dependence on hydrogen or of carbon, because the energy is not hot.
STFC-RAL-CR03 R61: For support.
STFC-RAL-CR03 R61: we have the positional reduced, and then we can align with the natural. So, this bondage of energy, is highly correlated to the nutritional energy itself.
STFC-RAL-CR03 R61: On the other hand, the neutron do some random walk, and then slow down, and then capture it.
STFC-RAL-CR03 R61: Little capture as a very nice feature. First of all, the energy is about too much for NV.
STFC-RAL-CR03 R61: So, if we relate it automatically, and then the capture energy, then we see, actually, we can identify the secret event away from the background.
STFC-RAL-CR03 R61: On the other hand, the actual, capture time is about…
STFC-RAL-CR03 R61: To me, our trigger time is 200 microseconds, and we can comfortably
STFC-RAL-CR03 R61: Select this time window, and also the distance between form.
STFC-RAL-CR03 R61: And then the next signal is…
STFC-RAL-CR03 R61: quite small. Actually, it can go up only to 1 meter, so we can also define this spatial restriction. So, all in all, for IDE, we have the triple coresiness selection.
STFC-RAL-CR03 R61: Of course, you have to worry about the background.
STFC-RAL-CR03 R61: What kinds of background do we have? We have the internal with the activity that I just mentioned before, and here specifically, the lithium helium one is very dangerous. It's caused by neuron bombardment of the liquid synthetic concentrating expedition.
STFC-RAL-CR03 R61: However, it will decay.
STFC-RAL-CR03 R61: in beta and also, neutron, it provides, actually, the very fake IBD process.
STFC-RAL-CR03 R61: And we have the natural radioactivity we just mentioned, and in addition, we have the external background coming from the world, geodes, and world vectors, and also from geolationals from those remaining thorium in the cross sediment.
STFC-RAL-CR03 R61: So… In order to select the rank.
STFC-RAL-CR03 R61: As I mentioned before, we first need to define the fiduciary volume, cut away the outermost layer. This is to guarantee that we don't have the contamination coming from our side, but also to guarantee that the trusted performance is fast.
STFC-RAL-CR03 R61: On the other hand, we, reject occasional PMT, math signatures, and also.
STFC-RAL-CR03 R61: Very importantly to remove anything related to N… Incoming.
STFC-RAL-CR03 R61: We will insert the detector.
STFC-RAL-CR03 R61: And we also require that we have exact, two triggers that is expected for the IBE, and after that, we perform, finally, the typical coincidence selection.
STFC-RAL-CR03 R61: So, the muon is so important because if it…
STFC-RAL-CR03 R61: Veto them, or there's delayed inactivity, we will have the internal activity contamination.
STFC-RAL-CR03 R61: So, let's first have a look how it is done.
STFC-RAL-CR03 R61: In the WCD, it is by the strength of light, and in fact, we see 9 thirds of neurons in this detector. And it can also detect in the CD by the energy signature and the spatial extension of it, so we have the five gates.
STFC-RAL-CR03 R61: If I could, for the new, registered in the city.
STFC-RAL-CR03 R61: And if we compare, to,
STFC-RAL-CR03 R61: triggers or signatures of the neuron. In the CDNWCD, we actually can determine the typing efficiency for the neurons.
STFC-RAL-CR03 R61: And it's almost 100%, so it's very good.
STFC-RAL-CR03 R61: If we look at the distribution of all these incoming yields, we see most of them coming from above, because we are an underground territory, this is expected. And here we see the data
STFC-RAL-CR03 R61: And Montal Greece went well for the stater.
STFC-RAL-CR03 R61: a smooth.
STFC-RAL-CR03 R61: The polar, distribution and also the osmosis distribution.
STFC-RAL-CR03 R61: This is not a sugar block, because the new hands.
STFC-RAL-CR03 R61: the overburden and the above-hole structure in a different, aus direction. If you remember from this, both sides view, we have actually a huge area.
STFC-RAL-CR03 R61: the data, or the color consistency, actually tell us we have modeled all this structure, precisely. So that's the flat normalization and shape.
STFC-RAL-CR03 R61: are consistent between data and cop.
STFC-RAL-CR03 R61: So, in the end, we have all these candidates along with us. Let's go through them one by one. First of all, for the low oscillated spectrum, we expect, a certain, signal rate, and the major
STFC-RAL-CR03 R61: Difficulty or dominating systematic disease is how we count the number of protons in the liquidate.
STFC-RAL-CR03 R61: So, it contributed to 41% in semantics, and also the react marks.
STFC-RAL-CR03 R61: currently is constrained by the police diability type data. So this reference spectrum has 1.2%, this is much error.
STFC-RAL-CR03 R61: And, of course, we have residual, the specific systematics that is related to Python.
STFC-RAL-CR03 R61: So the damsel nuclear power plant.
STFC-RAL-CR03 R61: And these are reported, respective somatics.
STFC-RAL-CR03 R61: In total, over these 60 days, of, physical support team.
STFC-RAL-CR03 R61: We have about 2,400 brands, so on average, 60, sorry, 40, candidates per day.
STFC-RAL-CR03 R61: If we look at the predicted background, in total, it's about 6 background percent.
STFC-RAL-CR03 R61: The most important crack one is the lithium imion, the cosmogen inspiration, Welcome to Malaysia.
STFC-RAL-CR03 R61: If we look at the sequel to Baton Ridge, it's about, A.
STFC-RAL-CR03 R61: In fact, this is always a very good number, because if you consider how shallow the experiment is.
STFC-RAL-CR03 R61: On the other hand, the second largest background comes from the jewelry, you know, and even though it's a background, but in fact, it's a very interesting digital literature.
STFC-RAL-CR03 R61: So, we have to collect all this event, for agency, and the major reduction of agency comes from the Finnish volume.
STFC-RAL-CR03 R61: And it also contributed that
STFC-RAL-CR03 R61: That is mathematics, and it's a problem 6%. The overall efficiency is about 70%.
STFC-RAL-CR03 R61: when we have, subtracted all the background, and then we should really be seeing the signal. And what happens if we look at it day by day, this is a very interesting observation, because we have the data, on the other hand, actually.
STFC-RAL-CR03 R61: is highly consistent with the predictions. The story is not bad.
STFC-RAL-CR03 R61: around 2013, September.
STFC-RAL-CR03 R61: There was a typhoon hitting the area, and one of… well, this is one of the strongest typhoons in the area.
STFC-RAL-CR03 R61: In the past, you know, few decades. I'm one of the directors
STFC-RAL-CR03 R61: code is turned off, therefore we directly see emitting
STFC-RAL-CR03 R61: or drop in the number of UMs. And then when it's…
STFC-RAL-CR03 R61: Die off, actually written on the other core.
STFC-RAL-CR03 R61: And at this point, in October, we turn off another call.
STFC-RAL-CR03 R61: So, basically, we see a world dynamic.
STFC-RAL-CR03 R61: Number of candidates increase here, and our data actually defines this channel.
STFC-RAL-CR03 R61: Precisely. Effectively, this plot shows us that we have achieved American real-time monitoring at a distance of 50 kilometers.
STFC-RAL-CR03 R61: And of course, it really depends on the core power.
STFC-RAL-CR03 R61: Now, after all the cooking, it's time to serve the dish. What we see here is the spectrum of our event candidate.
STFC-RAL-CR03 R61: That's a function of the top end.
STFC-RAL-CR03 R61: The dots are the data, and the big structure is to expect this question, the oscillation.
STFC-RAL-CR03 R61: So, immediately, you see the oscillation effect is very strong.
STFC-RAL-CR03 R61: And… With all the previous background, and this is the geological background, and then these are all the others.
STFC-RAL-CR03 R61: We have very high… And the overall spectrum.
STFC-RAL-CR03 R61: With the fitted surgeon promaker, this is in the back.
STFC-RAL-CR03 R61: So, when we compare the oxidative spectrum with the non-opsided spectrum, we see the distortion
STFC-RAL-CR03 R61: It's driven by the sort of missing payments.
STFC-RAL-CR03 R61: The background is under control, and all this
STFC-RAL-CR03 R61: observation has been done in three independent analysis groups.
STFC-RAL-CR03 R61: All the different machineries for selection, reconstruction, airport estimation, delivery response, and fitting, all differ in this free analysis code, and then they all achieve consistency.
STFC-RAL-CR03 R61: If we look at the soil mixing parameters, the creation…
STFC-RAL-CR03 R61: And comparison with other field submission.
STFC-RAL-CR03 R61: we have interesting oscillations. First of all, in terms of single experiment sensitivity, our general result has an robot that is 1.6 times smaller.
STFC-RAL-CR03 R61: The previous best one.
STFC-RAL-CR03 R61: And…
STFC-RAL-CR03 R61: Our result is a significant improvement, but standing on the shoulder of giants, of course, is better than the previous
STFC-RAL-CR03 R61: Particular case of nature.
STFC-RAL-CR03 R61: Genome meshing.
STFC-RAL-CR03 R61: And we only give a success to you based off data.
STFC-RAL-CR03 R61: If we look at the single family test.
STFC-RAL-CR03 R61: And the errors, we see that both parameters are old and true, The person never accrues.
STFC-RAL-CR03 R61: What is more interesting to my taste is that it's that M squared tool want, actually.
STFC-RAL-CR03 R61: as two groups. Our result is consistent with other
STFC-RAL-CR03 R61: oscillation experiments, however, The same quantities can be measured by…
STFC-RAL-CR03 R61: experiment using the machinery from the sun, and then they consistently
STFC-RAL-CR03 R61: Divide from the one from the reactants.
STFC-RAL-CR03 R61: So… Is there something interesting going on? We don't know. It's good to think about it.
STFC-RAL-CR03 R61: So, at this moment, we are transiting to a precision error for each, photonics in parameter literature.
STFC-RAL-CR03 R61: In fact, we have demonstrated that the present level measurement is possible as long as we have
STFC-RAL-CR03 R61: A much larger detection, and also high enough statistics.
STFC-RAL-CR03 R61: So beyond the first measurement, we expect to measure.
STFC-RAL-CR03 R61: Dude.
STFC-RAL-CR03 R61: So, not missing parameters, and also the delta M squared C1.
STFC-RAL-CR03 R61: To enter the sub-percent level accuracy.
STFC-RAL-CR03 R61: Up to 100 days of data.
STFC-RAL-CR03 R61: And for the mass ordering sensitivity, suppose we have normal ordering, then we would reach 3 sigma after 7.1 years.
STFC-RAL-CR03 R61: And if it is diverted forwarding, then the same exposure actually will give us 0.17.
STFC-RAL-CR03 R61: The vision of Juno is that
STFC-RAL-CR03 R61: 10 years' time, after 10 years, definitely before 20 years, the oscillation landscape will be.
STFC-RAL-CR03 R61: Undescripted.
STFC-RAL-CR03 R61: So, at that point, we would already know what the best product means, and what's the next…
STFC-RAL-CR03 R61: the focus. That would be the original storage decay. So, one proposal to upgrade the original experiment is to put
STFC-RAL-CR03 R61: a balloon?
STFC-RAL-CR03 R61: Inside the central detector.
STFC-RAL-CR03 R61: And this poll is filled in various niches in it, or pollution. It's not decided yet.
STFC-RAL-CR03 R61: But that would be a very interesting follow-up.
STFC-RAL-CR03 R61: However, overall.
STFC-RAL-CR03 R61: The observatory is designed for the next 30 years. The science exploration will good, but as you all have seen, there are solutions, and also visionaries for the Earth.
STFC-RAL-CR03 R61: But, in fact, we can also see material from the sun, from atmosphere, from perhaps below Earth, and also, Juno can search for obvious them, like the Earth can.
STFC-RAL-CR03 R61: So, for… the solar… There she knows.
STFC-RAL-CR03 R61: Dude.
STFC-RAL-CR03 R61: quickest way to understand how the measurement can be done is the following. We just, specify starts with the first four that
STFC-RAL-CR03 R61: accuracy, because the season, let's say, you know, is small, we can simply put it as silo, because we don't care about the long top flavor. So this sort of pinupon, basically.
STFC-RAL-CR03 R61: It comes a perfectly vertical oscillation.
STFC-RAL-CR03 R61: So here it becomes. In the center of the sun, the new eats produce.
STFC-RAL-CR03 R61: And it's this mixture of the mass 1 and 2.
STFC-RAL-CR03 R61: If dilution of energy is involved, The investment in true pocket.
STFC-RAL-CR03 R61: I see that emerging, and this merchant population continues.
STFC-RAL-CR03 R61: To us, because it is fast, there is enough to travel, they don't have computers or coherence anymore, they just add up.
STFC-RAL-CR03 R61: independently. Therefore, we have a survival property of the electron, Mark, please.
STFC-RAL-CR03 R61: So, a number of things, yeah.
STFC-RAL-CR03 R61: However, if we have the… high energy neutrinos from the sun.
STFC-RAL-CR03 R61: Because of the matter fact that most of the Latinos will
STFC-RAL-CR03 R61: be, in the, V2 at the surface of Sun, and then, again, it continues to propagate.
STFC-RAL-CR03 R61: In infection. And in this case, we have survival ability.
STFC-RAL-CR03 R61: Peter.
STFC-RAL-CR03 R61: But now, we have the question. We talk about low energy and high energy, but how high is high?
STFC-RAL-CR03 R61: In these two flavor observations, the only NH scale is that the N squared to 1. Therefore, actually, the NH scale is calculated by this. When you stretch.
STFC-RAL-CR03 R61: the true vineyards.
STFC-RAL-CR03 R61: We have this autonomi.
STFC-RAL-CR03 R61: If you can measure this by hand.
STFC-RAL-CR03 R61: We can match a distance and scratch one. This is the best idea.
STFC-RAL-CR03 R61: So, here in Juno, for difference, because M squared to 1, We have different…
STFC-RAL-CR03 R61: predicted human shape, or spectral shape, and you can see
STFC-RAL-CR03 R61: It's all in the MBU gym.
STFC-RAL-CR03 R61: Therefore, if we can measure the column 8 solutions, This measurement can be done.
STFC-RAL-CR03 R61: It's very interesting, because in one single experiment, you can measure the same basic quantity, mainly in solar mixing parameters.
STFC-RAL-CR03 R61: from directions, and also from machinery from the sun. This will give us direct comparison that relates to market impact for machinery's most anti-mutinals, or perhaps PSM.
STFC-RAL-CR03 R61: And in addition, we are also sensitive Sure, Arden.
STFC-RAL-CR03 R61: solution of species. I mentioned that we can actually pop inside the sun, period.
STFC-RAL-CR03 R61: It's very difficult.
STFC-RAL-CR03 R61: However, because the soil nutrients are all regions, not anti-lynees, therefore, the reaction happens not on the hydrogen, not on the carbon.
STFC-RAL-CR03 R61: It can only happen for electrons with analysis scaling. Of course, there are other small channels at 1%, weight that happen,
STFC-RAL-CR03 R61: But to the first, order, the next sketching is amazing attribution.
STFC-RAL-CR03 R61: That's… Beautiful.
STFC-RAL-CR03 R61: without the IPD, for instance, in this case, it's very difficult to select the line. Therefore, we have to control the background to the extreme level.
STFC-RAL-CR03 R61: Now, let me come to the end and some more. So, after certain years of effort, General is, deleted, and then run it, and the whole provision is so excited and happy, especially the younger generation, because they can actually play with the data.
STFC-RAL-CR03 R61: And the first, general result is using 26 days off.
STFC-RAL-CR03 R61: Data, and avoid producing what's needing results for those sort of permissions.
STFC-RAL-CR03 R61: And it has demonstrated.
STFC-RAL-CR03 R61: Alright, so precision.
STFC-RAL-CR03 R61: Mutino measurement, with 20 kilot 10 degrees centimeter as a baseline 50 kilometers.
STFC-RAL-CR03 R61: So, looking ahead, actually, what we have demonstrated is the validation of the digital performance in terms of the energy and background control made.
STFC-RAL-CR03 R61: All these key performance, usually at the sun level.
STFC-RAL-CR03 R61: And some of them are actually better than this time. But, the critical one.
STFC-RAL-CR03 R61: We're still working on, we're working on that, and it's mostly mapped.
STFC-RAL-CR03 R61: So, in the future, near future, towards the next ordering, we get past the thesis, And also optimize.
STFC-RAL-CR03 R61: In terms of performance. But most importantly, near detection.
STFC-RAL-CR03 R61: at the Taisha, you could call Trump.
STFC-RAL-CR03 R61: had just gone online of that belief. And when this data is used, we will use this to constrain additional files and provide a reference section.
STFC-RAL-CR03 R61: So instead of using the iPad, we actually can have our own data detection constraint.
STFC-RAL-CR03 R61: So, O in PO provides a diagnostic program for the next 40 years.
STFC-RAL-CR03 R61: Okay.
STFC-RAL-CR03 R61: Thank you again for very nice review.
STFC-RAL-CR03 R61: the whole experiment. So we have time for questions.
STFC-RAL-CR03 R61: Yes. I was, I was curious, like, the, 3 millimeters of,
STFC-RAL-CR03 R61: construction. What's the density of the liquid's insulator? How much does the detector change? When you change from liquid's insulated? It's lighter than water, therefore when you see, actually,
STFC-RAL-CR03 R61: Filling. We drain down the water and then pump it in the liquor syndrome as some form above.
STFC-RAL-CR03 R61: And you raised an important point, because There's only maximum one,
STFC-RAL-CR03 R61: pressure balance point between the water and the centenator. And then, actually, we have tuned it like that. It is always a negative pressure inside the vessel. Namely, always is the water pushing inside.
STFC-RAL-CR03 R61: That, is, better for the mechanical, integrity of the vessel, because it's easier to go against pressure, instead of, against the implosion from inside.
STFC-RAL-CR03 R61: So, all this mechanical stress.
STFC-RAL-CR03 R61: A stress on the acrylic vessel, and also the stainless steel structure has been in the calculation, and also monitored closely with the pressure sensors.
STFC-RAL-CR03 R61: So, I'm just trying to understand, does that mean that you've been controlling the pressure such that there was essentially no change?
STFC-RAL-CR03 R61: Shaking button, and I'm swapping for more general security.
STFC-RAL-CR03 R61: It's a dynamic process. We have to balance point by point, but eventually, it is the, balance point is not gone, so there's no balance point. But when we filled, we do have
STFC-RAL-CR03 R61: to, change starting point, and then see gradually how the whole system reacts. Because, it's fun… funny, when you see the strength, or the level, or the ground, it actually changes when you fail. So, it's really scary.
STFC-RAL-CR03 R61: what… what does it mean? But eventually, stabilize, and then everything is understood, I would say.
STFC-RAL-CR03 R61: So, nothing's really planned, but, thanks to all these, instant monitoring, we do have a gradual understanding of it.
STFC-RAL-CR03 R61: It's very impressive.
STFC-RAL-CR03 R61: So, you pointed out that, there's a, tension between data from, the sun and reaction.
STFC-RAL-CR03 R61: This is a solid tunnel token.
STFC-RAL-CR03 R61: So, is there, like, a future plan?
STFC-RAL-CR03 R61: schedule for Chuno to do that as well. Let's see if,
STFC-RAL-CR03 R61: If you can still see that tension, then the same… for this…
STFC-RAL-CR03 R61: Specific for this program, the, reactive part is mostly done, so what you…
STFC-RAL-CR03 R61: further do with the anti-affirmation from the earplates to shrink the air box. But then, on the other hand, Juno can also
STFC-RAL-CR03 R61: Measure the solutionals.
STFC-RAL-CR03 R61: itself, so… Yeah, to provide.
STFC-RAL-CR03 R61: the delta M squared to 1.
STFC-RAL-CR03 R61: consolidation, and hopefully we can also shrink the airports, and you'll actually see in one experiment.
STFC-RAL-CR03 R61: Whether we still have this discourse?
STFC-RAL-CR03 R61: Thank you.
STFC-RAL-CR03 R61: Yeah, any questions from Zoom?
STFC-RAL-CR03 R61: Sweet
STFC-RAL-CR03 R61: Next. So you, you had mentioned the possibility of supernova, perhaps is something you want to optimize. How much does that influence the DAQ?
STFC-RAL-CR03 R61: We have, that creates a trigger on that. So,
STFC-RAL-CR03 R61: It doesn't affect the, current drone scheme.
STFC-RAL-CR03 R61: It's surrounded.
STFC-RAL-CR03 R61: But then, I don't see a confliction in them, so…
STFC-RAL-CR03 R61: May I ask, how do these, data changing days are counted, and what is the downtime for
STFC-RAL-CR03 R61: ouch.
STFC-RAL-CR03 R61: What's the… Lifetime of the detector.
STFC-RAL-CR03 R61: So, first of all, we exclude all those, tests or bad data, and then we also have the, data put, television runs. They are also excluded, so the remaining time
STFC-RAL-CR03 R61: is, 1, and then we also have the DQ time defined as the thesis passed equation.
STFC-RAL-CR03 R61: Yeah, so this is how all those, periods are end up together, and then counted toward the 59 days. Oh, nice.
STFC-RAL-CR03 R61: Yeah, the uptime is, quite high, about 1976.
STFC-RAL-CR03 R61: Yes, so… I'll, yeah, consider that a little bit.
STFC-RAL-CR03 R61: And on slide 15,
STFC-RAL-CR03 R61: Sorry, I have… I always have a hard time understanding this plot. So, you have oscillation length on the right,
STFC-RAL-CR03 R61: Yeah, the energy, and then EVI. Can you please explain this a bit? How this is… the structure of this diagram? Yeah. Okay, so this is the energy of the additional values.
STFC-RAL-CR03 R61: And that is how far the machine will travel from the source to the detector. There's a distance of… yeah, this is the baseline.
STFC-RAL-CR03 R61: Yeah, and then, correspondingly put the, Expandemic.
STFC-RAL-CR03 R61: So, the left side GEV is the… Oh, obviously, converted.
STFC-RAL-CR03 R61: Hpasi becomes one, I would say.
STFC-RAL-CR03 R61: with this neutral unit, you just convert the L from the length to the energy.
STFC-RAL-CR03 R61: And, if you… then the Juno part is the… merely the…
STFC-RAL-CR03 R61: The yellow one. The journal is specific here, the baseline is 1.52 kilometers.
STFC-RAL-CR03 R61: So it's here at that energy will cause several…
STFC-RAL-CR03 R61: from, POM 1MB to 10MB, so there's an extension this away.
STFC-RAL-CR03 R61: But then the baseline is rather small, or… It's between those two black lines. No, no, no. The other baseline is the rental.
STFC-RAL-CR03 R61: It's a lot of experiment. Okay. So, for journalists, only it's not.
STFC-RAL-CR03 R61: Okay.
STFC-RAL-CR03 R61: By the way, Renault, is key, does not exist anymore.
STFC-RAL-CR03 R61: This product is in 2020, so it's a bit outdated. Okay. Nowadays, we are only talking about camera and druno, but then, Snow Plus Fusion also had, presented, solar mixing.
STFC-RAL-CR03 R61: Without form, get a sold, sold us also sitting here.
STFC-RAL-CR03 R61: Fantastic.
STFC-RAL-CR03 R61: Sorry, it reminded me of something else you mentioned early on, that if there were only two neutrina species, and there was no concept of a normal or inverted ordering.
STFC-RAL-CR03 R61: I was a little curious about that, I mean.
STFC-RAL-CR03 R61: I would sort of imagine it could make a difference to things whether the heavier neutrino is mostly electron, or mostly neon, if those are the two species that are in. It depends how you define things. What is the order you've defined things, right? So, you can always define one as the lightest one.
STFC-RAL-CR03 R61: And how is this, 2. And in this case, you just observe what is the composition of
STFC-RAL-CR03 R61: the different flavors to 1 and 22, that's all.
STFC-RAL-CR03 R61: So the essence of the three flavor, or hierarchy or order is that
STFC-RAL-CR03 R61: It's really… I understand the definition with three. I'm just sort of not sure that it follows that with two, it's not an interesting question.
STFC-RAL-CR03 R61: We, obviously you just have to measure the fractions, but…
STFC-RAL-CR03 R61: Yeah, and you make a good point. What happens if the two actually is dominated by the electron?
STFC-RAL-CR03 R61: Yeah, what you call this a mess of your mouth?
STFC-RAL-CR03 R61: That's But…
STFC-RAL-CR03 R61: Can I ask for your, projection for the 7-year measurement, whether that is impacted by the number of
STFC-RAL-CR03 R61: Accelerators around, or… and whether Adding a newer… accelerator would, reduce, or…
STFC-RAL-CR03 R61: How that period could be reduced.
STFC-RAL-CR03 R61: This, first of all, is statistics from the vectors, and also the detector performance. And we remember, in order to tease out the information of the mass ordering, we have to see the results.
STFC-RAL-CR03 R61: of the spectrum. That requires superb energy, resolution. And, the current projection is based on 3.1%.
STFC-RAL-CR03 R61: And we are observing 3.4%, so still some work to do then that actually limits our day. On the other hand, we also need to understand that on oscillative spectrum.
STFC-RAL-CR03 R61: Very well, and this is where the tau really had to come in. So, with the tau and better calibrations.
STFC-RAL-CR03 R61: we could achieve this 7.1 years, or, maybe, use to read and, performance and total improvement. Yeah, I think this is a really exciting point about the general experiment.
STFC-RAL-CR03 R61: And, yeah, just a comment, I think it's really impressive for such a short time, since the…
STFC-RAL-CR03 R61: Collection of data studies.
STFC-RAL-CR03 R61: Yeah. Yeah, thank you. But, yes, I guess everyone's curious about But the results, not true.
STFC-RAL-CR03 R61: Yes. I was also curious, I mean, the NT showed the picture, and the whole, thing is covered in the, sort of, some white material.
STFC-RAL-CR03 R61: Are you there?
STFC-RAL-CR03 R61: one of the photographs, the detective… For example, in the 41, slide 41? …looked white.
STFC-RAL-CR03 R61: Yeah, so what's this material which this is covering? Not the Tyvek.
STFC-RAL-CR03 R61: First of all.
STFC-RAL-CR03 R61: This is the, high density polyethylene, and this is, the Tyrag. They're all, effective, so, to improve the optical separation between different parts.
STFC-RAL-CR03 R61: And also, this one can shield from the, shield the radioactivity, stop the material coming from inside, because the wall is dirty.
STFC-RAL-CR03 R61: Tyler is a family material, it's actually a brand.
STFC-RAL-CR03 R61: So… but then it has been used in, basically, many original experiments to use optical separation.
STFC-RAL-CR03 R61: Do you know where it is produced?
STFC-RAL-CR03 R61: Mmm… Maybe, well, I know people buy it from China.
STFC-RAL-CR03 R61: And, where are other places? I don't know, actually. It's commentary, actually.
STFC-RAL-CR03 R61: I think I've seen it in construction.
STFC-RAL-CR03 R61: Which comes up?
STFC-RAL-CR03 R61: like, buildings, or… Oh, long distance. Because, I would say this time that we soon, have some,
STFC-RAL-CR03 R61: Yeah, let's fax that.
STFC-RAL-CR03 R61: is beyond, some construction. For construction, it's just shielded dust, right? Right. It's more than that. Oh, it's, yeah. Sure.
STFC-RAL-CR03 R61: Okay.
STFC-RAL-CR03 R61: Because it has to be immersed in liquid.
STFC-RAL-CR03 R61: Yes.
STFC-RAL-CR03 R61: Okay, and let's thank, Shambo.
STFC-RAL-CR03 R61: And we love the center here, and also. Thank you very much. Please join for lunch with us, and take some cookies with you.
