WEBVTT 00:01:36.000 --> 00:01:51.000 There has no electric charge and it has no marks. So the first question is, how do we actually know there are different neutrinos? So I call them phasing shields, actually. 00:01:51.000 --> 00:02:01.000 But you know when you turn into M actually can produce charge buckles and these different species produce different charges. 00:02:01.000 --> 00:02:12.000 that fault, and thereby we have… So everything becomes a bit familiar and normal. 00:02:12.000 --> 00:02:32.000 You can send the model. However… nature is different slightly. So we know that she must have some mass, and that actually gives us another way to recognize the neutritionals. But are they the same as the flavor way to see the machines? 00:02:32.000 --> 00:02:46.000 This is the problem about machinery identification. So that in the center model we have the flavor eigenstate, and then we also have now the best I can say. And in fact, they are connected by the so-called. 00:02:46.000 --> 00:02:56.000 Let's not go into this detail yet, but recognize that if you have massive masses, what does it mean? 00:02:56.000 --> 00:03:12.000 So, one has to be the smallest, of course, and then the other has to be large. Then what is the minimum? 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. 00:03:12.000 --> 00:03:22.000 The market is actually close to a large one, we have diverted order. So from this narrative, all the mass ordering, or the so-called mass hierarchy. 00:03:22.000 --> 00:03:29.000 This is in fact… For problem, when there are more than two masks. 00:03:29.000 --> 00:03:36.000 This is very interesting. What's more interesting is that now we have the mass gaps. 00:03:36.000 --> 00:03:50.000 And also, the ice state mixing. Then we actually produce neutrino oscillations. This is a very blank statement. But in fact, we can understand this by a doctor's analogy. 00:03:50.000 --> 00:04:06.000 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 the X and Y state. So as time goes on. 00:04:06.000 --> 00:04:28.000 The X and Y states actually oscillate. This is the same thing mathematically as our solution. So we see here, and she knows how the mass gap and also the mixing Ms. And eventually we see the play will either survive or appear. So these are the same probabilities as in the spin rotation case. 00:04:28.000 --> 00:04:38.000 But now the face is a function of the mass gap at m squared, and there's a function of the L over daseline and additional energy. 00:04:38.000 --> 00:04:45.000 So now… By far, we haven't really talked about specifics about the. 00:04:45.000 --> 00:05:00.000 That's getms that nature. What is more important at the moment is to ask the question whether all these flavors participate in oxygenation or two or three flavors. This is an important question because. 00:05:00.000 --> 00:05:17.000 If we had just two flavors. Then they can change all the observation. Probability is so strong that there's no difference between machine oscillation and anti-machine oscillation. However, when we have 3 frame oscillations, this additional equal frequency. 00:05:17.000 --> 00:05:24.000 can allow the future practice to be different between humans and anti-link tumors, and thereby could potentially. 00:05:24.000 --> 00:05:30.000 I'm not sure if it's so-called CP violation. That's not acceptable. 00:05:30.000 --> 00:05:38.000 So can we to some specifics about the marks. We know 3 different states. So 2 independent math gaps. 00:05:38.000 --> 00:05:43.000 The big one is 30 times larger than the small one. 00:05:43.000 --> 00:05:52.000 And now, by definition, the small one is always the 2 minus 1, and therefore the term square is always. 00:05:52.000 --> 00:06:02.000 Okay. The only possibility to arrange the third state that is further beyond the tube, which is the normal hierarchy. 00:06:02.000 --> 00:06:14.000 You know the first there is this emerged volunteer mass voting almost hierarchy is interchangeable in my notice here. 00:06:14.000 --> 00:06:31.000 Let's look into the Pms metrics. It's a bit complicated. But in fact, we can dissect it in the following world. So the one truth is missing between the mass one and mass 2 state, and 2, 3 is about the new power state. 00:06:31.000 --> 00:06:40.000 Then the theta one suits were interesting, because if C13 is 0, then effectively have a proof flavor missing. 00:06:40.000 --> 00:06:48.000 And by the discussion before you guys in such a case, we won't be able to look at CPE evaluation. 00:06:48.000 --> 00:06:57.000 And luckily, this FTCP is not zero and the Delta CP. 00:06:57.000 --> 00:07:01.000 So what is the opening question in the machine? 00:07:01.000 --> 00:07:14.000 First of all, we won't be able to measure a certain amounts with extreme oscillations. Therefore, if you want to know about electrical masses, we can only know about the gaps, like the M squared. 00:07:14.000 --> 00:07:22.000 And we also want to know more how they meet the missing parameters needs to be better determined. 00:07:22.000 --> 00:07:39.000 So with all this interesting topics, what can we do? So we have definition of sources. And here is a summary as a function of additional energy. You see the Mdv and the JV. 00:07:39.000 --> 00:07:43.000 Yeah, so around this fusion, we have solar channels, geodesinos. 00:07:43.000 --> 00:07:50.000 And the fact that she knows. And of course, our associations also. 00:07:50.000 --> 00:08:03.000 if we are concerned with machine oscillations, then we will probably first look at solution those right solutions, accelerator and atmospheric machiners. 00:08:03.000 --> 00:08:09.000 But interesting fact is that for the solution. machines. 00:08:09.000 --> 00:08:15.000 of the electrical labor. And in contrast, the reaction is anti-Electronics. 00:08:15.000 --> 00:08:25.000 And as long as oscillation is concerned for a certain tumors, we are above and beyond. 00:08:25.000 --> 00:08:32.000 So just remind ourselves that there are only two independent M squares. 00:08:32.000 --> 00:08:45.000 And the solution phase is proportional to a deltron squared by L over e. So what happens if we put all experiments in a diagram with the energy and the baseline L? 00:08:45.000 --> 00:08:56.000 So here we have the MVV and the GV regime, and the one kilometer baseline, a thousand kilometer baseline. So we'll see actually we have one clusters. 00:08:56.000 --> 00:09:00.000 We have one question here for the rectal department. 00:09:00.000 --> 00:09:05.000 And they're outcaster of Basuita and Australian Park Stone. 00:09:05.000 --> 00:09:12.000 Now the 2 things looking in the same perspective, because they're on the same level. 00:09:12.000 --> 00:09:28.000 Therefore, let's actually pop in the center and square, which is the last one, the large one, because the delta N. Square is large. Therefore, they already just need to be small to show the oscillator and is fast. 00:09:28.000 --> 00:09:31.000 Observation. Well, still with the Victoria. 00:09:31.000 --> 00:09:37.000 We can actually extend the baseline and we see a lot of. 00:09:37.000 --> 00:09:53.000 our cluster here, and it's from a different amount of the Lobe. And in fact, it's sentient to the smaller M. And because the transfer is small, it takes more time or long distance to see oscillation. Therefore, it is a slow. 00:09:53.000 --> 00:10:04.000 oscillation. So also you see all these clusters have their relative strength in measuring all the parameters. Here, this was 3. 00:10:04.000 --> 00:10:14.000 And also here, this one, too. And the time square of all matched. So this end of story, isn't it? 00:10:14.000 --> 00:10:22.000 Is there anything more? So, what you're seeing here is the. 00:10:22.000 --> 00:10:27.000 Survival property of the reactor anti-neutamers as a function of the baseline. 00:10:27.000 --> 00:10:36.000 How long did the parting measurement using certain machinos to measure this small oscillation? 00:10:36.000 --> 00:10:47.000 It's really high level. It is the first time that we actually measured this so-called solar mixing parameters with reactors. 00:10:47.000 --> 00:10:52.000 But you can see, because they are family, they didn't really sit at. 00:10:52.000 --> 00:10:57.000 the advanced location. And you know, with all this hindsight. 00:10:57.000 --> 00:11:07.000 is viewed as no oscillation. Oscillation maximum here. Therefore, it's extremely sensitive to this solar message. 00:11:07.000 --> 00:11:18.000 And the best focus will be… doing those measurement of this colonists in canvas and the genome performance that this first result is based on. 00:11:18.000 --> 00:11:31.000 Of course. Arjuno is built for more. If you look more closely now we can focus on the blue line, which is small oscillation, maybe it's fast one sitting on the slow one. 00:11:31.000 --> 00:11:38.000 This is very interesting because, in fact, if you look at. 00:11:38.000 --> 00:11:46.000 How the framework evolved between the initial flavor and the new and current flavor. This is something like that. 00:11:46.000 --> 00:12:03.000 So, pure, and then graduate. maximum only towards maximum conversion to the real flavor and the tall flavor. So this is at the Juno baseline. Once the. 00:12:03.000 --> 00:12:11.000 She must pass the original phase not. You actually see following the large oscillation. It comes back. 00:12:11.000 --> 00:12:15.000 Back and forth, back and forth. The small, because two states. 00:12:15.000 --> 00:12:19.000 This is important because… This small vehicle. 00:12:19.000 --> 00:12:32.000 Actually, is sensitive to the mass movement. So it depends on whether it's normal holding or inverted ordering. 00:12:32.000 --> 00:12:40.000 And, you know, it's magnificious, we try to measure neutral mass audit by measuring. 00:12:40.000 --> 00:12:49.000 The oscillation spectrum. So, first things first, what do we want to measure between your mass body in the first place? 00:12:49.000 --> 00:13:05.000 Well, um, I haven't seen an artific colleague. Yeah. But I think it is a fair statement that even if you know about mass apartment, it will be extremely difficult. 00:13:05.000 --> 00:13:09.000 commercial that the Cp. You can imagine in a scenario that. 00:13:09.000 --> 00:13:20.000 Nature is normal ordering, but that one experiment actually measured the decision in discrete area in this phase. But the other experiment measured. 00:13:20.000 --> 00:13:26.000 That doesn't seem to be different. I'm expects. 00:13:26.000 --> 00:13:31.000 Uh, not to mention that at the moment, we don't know which order it is. 00:13:31.000 --> 00:13:40.000 On the other hand, in order to tell the neutrino CS model of Dirac, we could perform a search for the Chinese propagate. 00:13:40.000 --> 00:13:47.000 What happens if we are already sensitive to the mass in this region, or still haven't found anything? 00:13:47.000 --> 00:13:55.000 and the interpretation really depends on the mass quantity inverted bordering 5 means there's no. 00:13:55.000 --> 00:14:03.000 Different specific which one is appropriate decay, and therefore rituals are derived particle. But. 00:14:03.000 --> 00:14:12.000 If unfortunately or unfortunately it is normal holding, then it means that we just have to work much farther. 00:14:12.000 --> 00:14:18.000 To try to look for the most appropriate. So mask only matters or not. 00:14:18.000 --> 00:14:26.000 to take our strategic plan as well. So we also influence. 00:14:26.000 --> 00:14:34.000 The sum of the original mass in cosmology, and it is also vasopod. 00:14:34.000 --> 00:14:40.000 in the regime of labor evolution of supernova machines. 00:14:40.000 --> 00:14:45.000 So question. Do you know is in the south part of China. 00:14:45.000 --> 00:14:52.000 Yeah, if you zoom in, you will see that is 52.5 kilometers. 00:14:52.000 --> 00:14:57.000 away from two big power plants, the Longjiang Baker Pop Plant. 00:14:57.000 --> 00:15:16.000 And also the problem. And you cannot cut some names here. This is my hometown. So this whole area is the so-called Guangdong Hong Kong River Bavaria. 00:15:16.000 --> 00:15:28.000 One of the powerhouses of the Chinese economy. The Journal of Corporation have set more than 700 participants. 00:15:28.000 --> 00:15:36.000 And we have our strong team in Europe, for example, and the UK work started in officially. 00:15:36.000 --> 00:15:47.000 And that. It's a partner corporation. You see our curvatures. 00:15:47.000 --> 00:15:54.000 at the time to help local farmers, but just enough time to cut these small patches to not hold fish. 00:15:54.000 --> 00:16:01.000 And, uh, we try to make… this is special type of ice. 00:16:01.000 --> 00:16:10.000 coaching would take. So, you know, is underground lab. So this is the god. Yeah. 00:16:10.000 --> 00:16:22.000 500 meters deep, we have experimental hole because it is in a huge area. In fact, we have about 700 watts over Earth. 00:16:22.000 --> 00:16:29.000 It looks like this. on Sky, and here is the entrance of ground. 00:16:29.000 --> 00:16:37.000 to the lab, and also this earth engines. So either we take the slope tunnel. 00:16:37.000 --> 00:16:49.000 So, uh, 1000 meters in this very interesting card or actually take the leaf down section bites from the vertical shot. 00:16:49.000 --> 00:16:55.000 What you see here now is the, um… do not detect it. 00:16:55.000 --> 00:17:03.000 The biggest structure is the cylindrical. will tech. It has a diameter 43 points. 00:17:03.000 --> 00:17:17.000 Why can you testify the height is 44 meters, and you find that this is article 7 regions. The outer one is Schenkov detector with 35 kilohm of water. 00:17:17.000 --> 00:17:28.000 So then the inner part I will talk more about it later is the 5 pyotomotor of below the time ax. 00:17:28.000 --> 00:17:33.000 So the target actually sits on the stainless steel structure. 00:17:33.000 --> 00:17:41.000 So this is the hosting structure. I'm going to sit on it, and this structure actually holds. 00:17:41.000 --> 00:17:48.000 Some veto PMPs. 2,000… looking outwards into the water. 00:17:48.000 --> 00:17:54.000 And also, uh, some large PMPs looking inwards towards. 00:17:54.000 --> 00:18:01.000 in the structure, and also with small PMPs. So, in total, we have. 00:18:01.000 --> 00:18:10.000 Uh, about 18. I think thousands of large PMGs or 26,000 small PMTs. In total, they travel. 00:18:10.000 --> 00:18:18.000 78% of the area. So this audio coverage is a scary number. 00:18:18.000 --> 00:18:25.000 Because 78% means that the holding structure, the same structure only can have. 00:18:25.000 --> 00:18:36.000 mechanical precision. If things get worse, there's no way to feed them together. 00:18:36.000 --> 00:18:40.000 It will be a disaster, but we actually manage it. 00:18:40.000 --> 00:18:53.000 So, continue to peel the onion, you can see the innermost part is the acrylic vessel. It has a diameter of 35.4 meters. 00:18:53.000 --> 00:19:08.000 And, uh, inside it hosts 20,000, increasing temperature. The scintillator like usually around 430 nanometer. It is the white blue. 00:19:08.000 --> 00:19:16.000 like this. So everything is just on paper. Now let's look at some folders. 00:19:16.000 --> 00:19:30.000 So here, all we see is a stainless steel structure, and beneath it is the part of the acrylic vessel. So assume are the workers. Yeah. 00:19:30.000 --> 00:19:42.000 And now you can see actually the little PMTs on the same structure, and actually look closer. You can see the back of the large pin is really being stuck. 00:19:42.000 --> 00:19:59.000 So now, if you look at here, this is a flat show. And then this is supporting row for the structure. And you can see the large PM piece and also small PMTs. 00:19:59.000 --> 00:20:10.000 And this buffer error is actually quite large. Okay, or it has the… Yeah, for all of 5 meters. 00:20:10.000 --> 00:20:23.000 in China in 2013 and then 2014 for the victory and so on and so forth. 00:20:23.000 --> 00:20:43.000 And the civil construction started in 2015. We have a great challenge to tackle because of the underground water, and then later towards the decade, we will hit by COVID and eventually the zero construction was finished in 2022. 00:20:43.000 --> 00:20:56.000 And then we started the detective donation. And this whole thing. 00:20:56.000 --> 00:21:20.000 serious effort, you know, 30 seconds. 00:21:20.000 --> 00:21:35.000 So it's not just an event. If we look at the status in 2022, then 2023, and then 4, and this is. 00:21:35.000 --> 00:21:46.000 Right before everything is finished. And here is a comparison. When we first touch on to the base, it looks like star row f stop. 00:21:46.000 --> 00:21:55.000 Awesome. And here, uh… You see the happy faces of everyone. 00:21:55.000 --> 00:21:59.000 But this is not done yet. We need to clean the vessel. 00:21:59.000 --> 00:22:05.000 So actually, we used a high pressure water gummy spray it. 00:22:05.000 --> 00:22:18.000 It's mesmerizing, isn't you can look at the whole thing. But, uh… Let's continue. After it's done, we can see the vessels like this. All these files fold. 00:22:18.000 --> 00:22:22.000 spots are actually the joint for the supporting role. 00:22:22.000 --> 00:22:33.000 On the things you structure and do the rest of you can see behind actually all those TMTs. 00:22:33.000 --> 00:22:42.000 So once this is done, you can actually fill the whole detector and also the inside of the hypertic vessel with water. 00:22:42.000 --> 00:22:54.000 pure water, and it was started in… On December 24th, after 2 months, this hand it looks like this. 00:22:54.000 --> 00:23:07.000 So, from February 2025, we start to replace the water in this detector with nitro synthetic. It's a very delicate process. 00:23:07.000 --> 00:23:13.000 Therefore, it took six months to finish. But then when it's finished. 00:23:13.000 --> 00:23:33.000 We move on quickly. So in August. finished our fillings finished, we start the calibration campaign and on the 26th of quarter, we start this completion. You can see. 00:23:33.000 --> 00:23:41.000 The initial text when the random rate of cancellation is high and gradually decays out. 00:23:41.000 --> 00:23:57.000 After some tests, we start to connect. This is quality data, and by the time of the beginning of November, we have connected 69 calendar days of data, and this corresponds to 59.1 visits. 00:23:57.000 --> 00:24:02.000 Fortune Database. 00:24:02.000 --> 00:24:14.000 But actually, during the calibration campaign before the study, we actually have already seen regular visuals, and that is. 00:24:14.000 --> 00:24:26.000 Let's pay for one of the good things. Now we talk about the acidic characteristic data, but basically you first see a prompt positive signal. 00:24:26.000 --> 00:24:43.000 And then DFI, you also see a DNA neutral signal. So spatial displacement is all one meter or less, and then the time is a few hundred microns. 00:24:43.000 --> 00:24:52.000 So one goal performance impacts is the attenuation length for the liquid generator and also for the water. 00:24:52.000 --> 00:25:00.000 Of course, or for the center detector. The attention that actually. 00:25:00.000 --> 00:25:10.000 It's critical to tell us how much the life we receive. And also remember our. 00:25:10.000 --> 00:25:21.000 radius of our ancient features. So if the attenuation length is too low, it means that the photon might not even get to this PMPs. 00:25:21.000 --> 00:25:29.000 or public muscle depends on where the demand is. There could be an uniformity. 00:25:29.000 --> 00:25:49.000 of the data forms. So we… try to, um… achieve a very low attenuation length. So for the central detector, the design goal of continuity test. And we have actually shift our value to 6 meters at the relevant. 00:25:49.000 --> 00:26:05.000 We've done. And for the water version of the attacker that the cycle is 40 meters of attenuation length. But with ultra pure water, actually we have to achieve 70 meters. 00:26:05.000 --> 00:26:15.000 The… And we actually are looking at the low energy and therefore visual purity is important. 00:26:15.000 --> 00:26:23.000 We have powerful internal reader activities from two major sources. First of all is the cosmogenic speculation. 00:26:23.000 --> 00:26:34.000 When mules come into the detector and they interact, actually it can produce all this transition product. On the other hand, the material itself. 00:26:34.000 --> 00:26:41.000 contempli. room, 4 rooms, and so forth. All this decay. 00:26:41.000 --> 00:26:52.000 virtually to our past waiters. On the one hand, they are conditioned, of course. On the other hand actually provide us an ideal unit. 00:26:52.000 --> 00:27:02.000 Vibration source for half of the sample, and specifically, if you look at this particular chain bipole, so-called bipole 2 and 4. 00:27:02.000 --> 00:27:10.000 Yeah. So this moves and also long decades to. 00:27:10.000 --> 00:27:21.000 operator is a homeschool, and the alpha. This has a very nice characteristic coincidence, and that we can identify them easily. 00:27:21.000 --> 00:27:27.000 Maybe it would be very helpful. So by measuring the FIFO, we actually have an idea. 00:27:27.000 --> 00:27:36.000 talk to your activities. are getting inside the detector and also die so by the time. 00:27:36.000 --> 00:27:49.000 Well, during the commission, we actually measure all these radioactivity inside the city and also the water treatment of the actor. You see that. 00:27:49.000 --> 00:27:56.000 All this contaminations. title is already achieved design level or even better than the design. 00:27:56.000 --> 00:28:07.000 It's actually tremendous, and allergy would be to achieve all this is equivalent to have less than 10 milligrams of nuts. 00:28:07.000 --> 00:28:13.000 the whole time of Europe. Yes, many photos of magnitude. 00:28:13.000 --> 00:28:23.000 Uh, control. So… Fortunately, the energy solution is very important. Therefore, we actually need to calibrate. 00:28:23.000 --> 00:28:32.000 This is our city and we can actually call the source around the z-axis and also we can put the source. 00:28:32.000 --> 00:28:40.000 Radioactive source, cohesion source of a smooth plant here, or around the vessel cell. 00:28:40.000 --> 00:28:49.000 This is the exact deployment plan. So, we have a system on 127 back in 854. 00:28:49.000 --> 00:29:01.000 They all have different gamers and different energies. They are both important axis. 00:29:01.000 --> 00:29:10.000 And we also have the same current source that gives us the gamma signal and also the DNA neutron capture gamma signals. 00:29:10.000 --> 00:29:17.000 And they are deployed on the axis and also on this CRS system. 00:29:17.000 --> 00:29:27.000 So with all this. We actually can understand the nonlinearity. 00:29:27.000 --> 00:29:37.000 of the energy is false. And in fact, our understanding is better than 1%. 00:29:37.000 --> 00:29:42.000 If you look at our projected energy. compared to the expected one. 00:29:42.000 --> 00:29:48.000 We have achieved an understanding of the energy scale president. 00:29:48.000 --> 00:30:01.000 0.5%. 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. 00:30:01.000 --> 00:30:13.000 They don't worry that much. It's a good indication of the uniformity. And of course, when things happen near the boundary of the aquatic vessel, this becomes. 00:30:13.000 --> 00:30:26.000 were difficult to come to this nature. So… inside bulk of the fiduciary. Actually, the form of discretion. 00:30:26.000 --> 00:30:36.000 So coming to the energy calibration, the eventual assessment style. 00:30:36.000 --> 00:30:41.000 And look at the energy reception. It's all better than 0%. 00:30:41.000 --> 00:31:06.000 which is close to 1 Ambit. The, um… The solution is 6.4%, you might say, okay, it's good enough. But in fact, it's still worth than the expectation of 0.1%. But remember that. 00:31:06.000 --> 00:31:13.000 It's only 60 things for… And we are still trying to improve the conjunction. And with that. 00:31:13.000 --> 00:31:35.000 But the methods and also better energy consumption. So the timing of the event is very useful for 2 reasons. 1st is to reject backgrounds and also the information used in the spatial. Construction. Then the vertex contraction. 00:31:35.000 --> 00:31:47.000 So we can see in this slide is that the event level procedural pandemic actual measured time compared to the expected time for the event. 00:31:47.000 --> 00:31:53.000 Looks like this for the PMT and also the Chinese for both of them. 00:31:53.000 --> 00:32:08.000 you see the prompt for rifle p and also the latest magic square by the model. So this is very important because it means that we understand the time spots of our Pngts, and this is consistent with the design. 00:32:08.000 --> 00:32:20.000 It's not a limiting fact. So all this performance is sufficient for background read work and also for the… vertex reconstruction. 00:32:20.000 --> 00:32:33.000 So the spatial reconstruction is that we use the term information and also potentially with energy information to be constructed wherever is happening inside this hole of simulation. 00:32:33.000 --> 00:32:47.000 So we put the German source from the left axis and then you can jump the set component of the vertex. And we can see the bias is within 10 centimeters. 00:32:47.000 --> 00:33:00.000 Oh, this is good. And the deviation is not just at the boundary, and on the other hand, the resolution of this deconstruction is using 10 to 10 centimeter. 00:33:00.000 --> 00:33:12.000 10 to 20 centimeters. So you see, actually, in both cases, the boundary effect is very strong. On the one hand, the light connection is not uniform, and it's sometimes messed. 00:33:12.000 --> 00:33:24.000 And also, when you're close to 100, the total refraction actually happens, and they change the optical purpose very much. Therefore, boundary is always a difficult region. 00:33:24.000 --> 00:33:31.000 And, um, yeah, we have not many information this talk. First of all. 00:33:31.000 --> 00:33:37.000 This shows that you went raised at the outermost 10 centimeters. 00:33:37.000 --> 00:33:45.000 Inside a critical vessel. So, what you see is that you can adjust the position of the environment. 00:33:45.000 --> 00:33:56.000 And you see all these bright spots. They are actually the external negative activity coming from the joint from. 00:33:56.000 --> 00:34:10.000 So we see that in the outer part of a critical vessel actually is regulated because of the external radioactivity is that in all screening. 00:34:10.000 --> 00:34:19.000 The optical performance. Display path, and for this region, we actually need to cut out. 00:34:19.000 --> 00:34:32.000 work. But overall, the voltage deconjunction is sufficient for mass selection. 00:34:32.000 --> 00:34:38.000 that could define the traditional boarding. And also, if you want to correct for any. 00:34:38.000 --> 00:34:46.000 Long uniformity, then the word conduction would be used. 00:34:46.000 --> 00:34:52.000 Well, let's look at the fiscal plan. What happens if an electron? 00:34:52.000 --> 00:34:58.000 Uh, which, you know, comes in inside the detector. So. 00:34:58.000 --> 00:35:07.000 We'll be looking at so-called university with a reaction sequence of hydrogen or carbon because the energy is more hot. 00:35:07.000 --> 00:35:23.000 And for support. We have the position for this, and then we can align the existing natural. So this function of energy is called energy is highly correlated to the nutritional energy side. 00:35:23.000 --> 00:35:31.000 On the other hand, the neutron does a random walk and then slow down and then capture it. 00:35:31.000 --> 00:35:42.000 First of all, the energy is about 2.2 energy. 00:35:42.000 --> 00:35:54.000 So, if we correlate the prompt energy and then the capture energy, then we see actually we can identify the secret divide away from the backhaul. 00:35:54.000 --> 00:36:04.000 We'll go ahead. The actual picture type is about… To me, uh, cryptocurren is to 100 microsecond, and we can comfortably. 00:36:04.000 --> 00:36:09.000 Select this time window and also the distance between form. 00:36:09.000 --> 00:36:27.000 And then the next signal is quite small. Actually, it can go up only to one meter, so we can also define this spatial restriction. So all in all, for IDE, we have the triple coincidence selection. 00:36:27.000 --> 00:36:42.000 Of course, you have to worry about the background. What kinds of background do we have? We have the internal with the activity that I just mentioned before, and here specifically the decent helium one is very dangerous. This caused by muon bombardment. 00:36:42.000 --> 00:36:57.000 of the Lucas Intellectualization. However, it will decay. in beta, and also neutron. It provides actually the very fake IBD constraints. 00:36:57.000 --> 00:37:17.000 And we have done natural radioactivity we just mentioned. And in addition, we have the external background coming from the word jewelry and word vectors and also for geological in the cross-segment. 00:37:17.000 --> 00:37:33.000 So in order to select the event, 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 continuation coming from outside, but also guarantee that. 00:37:33.000 --> 00:37:44.000 you can adjust the performance is fast. On the other hand, me, I reject occasional community events signatures and also. 00:37:44.000 --> 00:37:49.000 A very important to remove anything related to N. 00:37:49.000 --> 00:38:01.000 Incoming build inside the detector. And we also require that we have effect to triggers that is expected for the IBD. 00:38:01.000 --> 00:38:06.000 And after that, we perform, finally, the pito coresistance selection. 00:38:06.000 --> 00:38:12.000 So the muon is so important because if it. 00:38:12.000 --> 00:38:30.000 Activity contamination. So let's first have a look how it is done in the WCD. It is high supply and in fact, we see 9/3 of neurons in this detection. 00:38:30.000 --> 00:38:39.000 And it can also detect in the city by the energy signature and the spatial extension of it. So we have the 5 p. 00:38:39.000 --> 00:38:46.000 If I could for the real issue in the city. 00:38:46.000 --> 00:39:04.000 And if we compare the, um… the CD and WCD, we actually can determine the attacking efficiency for the neurons. And it's almost 100%. So it's very good. 00:39:04.000 --> 00:39:17.000 If we look at the distribution of all these incoming mules, we see most of continuing for the thought because we are an underground world trade, this is expected. And here we see the data. 00:39:17.000 --> 00:39:27.000 And we'll call this real world changes. possible. The polar distribution, and also the smooth distribution. 00:39:27.000 --> 00:39:43.000 This is not sugar block, because when you have the overburden and the above wall structure in a different ostmotic direction. If you remember from this bird size view, we have actually a healing. 00:39:43.000 --> 00:39:53.000 Yeah. The data, what the colorful system actually tell us we have more for this structure precisely. So that's the flux normalization and shape. 00:39:53.000 --> 00:40:14.000 a consistent between data and what coal. So in the end, we have all this candidate numbers. Let's go through them one by one. First of all, for the node osimated spectrum, we expect a certain signal rate and. 00:40:14.000 --> 00:40:23.000 The major difficulty or dominating systematis is how we count the number of protons in the liquid. 00:40:23.000 --> 00:40:30.000 So it contributes to about 1% is semantics. And also the rep class. 00:40:30.000 --> 00:40:41.000 community is constrained by the belief that they need to detect the data. So this reference spectrum has 1.2% systematic error. 00:40:41.000 --> 00:40:50.000 And, of course, we have to issue your specific semantics that is related to Python. 00:40:50.000 --> 00:40:58.000 So the downtime to a problem. And this appointed with respect to matrix. 00:40:58.000 --> 00:41:05.000 In control over these 6 days of this is approaching. 00:41:05.000 --> 00:41:15.000 We have about 2,400 ranks, so on average, sorry, 40 candidates per day. 00:41:15.000 --> 00:41:24.000 If we look at the predicted outcome in total it's about six outcomes. 00:41:24.000 --> 00:41:32.000 The most important fact one is more joint inspiration. 00:41:32.000 --> 00:41:39.000 of contamination. If we look at the SQL2 Python, which is about anything. 00:41:39.000 --> 00:41:46.000 In fact, this is already a very good number, because if we consider how shallow the experiment is. 00:41:46.000 --> 00:41:59.000 On the other hand, the secondary spectrum comes from the Juliano. And even though it's a backbone, but in fact, it's a very interesting physical literature. 00:41:59.000 --> 00:42:09.000 So, we have to correct all this event for agency, and the major industrial agency comes from in terms of the finished volume. 00:42:09.000 --> 00:42:22.000 And they also contribute to the… the overall efficiency is about 70%. 00:42:22.000 --> 00:42:33.000 When we first attracted for the background and then we should really be seen in our signal. And what happens if we look at the data by then. 00:42:33.000 --> 00:42:39.000 This is a very interesting solution because we have the data, on the other hand, actually. 00:42:39.000 --> 00:42:45.000 It's home consistent with the predictions. The story is made back. 00:42:45.000 --> 00:42:55.000 Around 2015 September. There was a hacking within that area and one of what this is one of the strongest type of area. 00:42:55.000 --> 00:43:05.000 Uh, in the past, you know, few decades. And one of the director who is turned off. Therefore, we directly see the meeting. 00:43:05.000 --> 00:43:14.000 or drop in the number of events. And then when it's… uh, tie off actually read to know about the call. 00:43:14.000 --> 00:43:23.000 And at this point, in October, we cannot allow the call. So basically, we see our dynamic. 00:43:23.000 --> 00:43:30.000 I love all kinds of things can increase, yeah, and our data actually affects this channel. 00:43:30.000 --> 00:43:40.000 Precisely. Effectively, these ports show us that we have achieved real-time monitoring at a distance of 50 kilometers. 00:43:40.000 --> 00:43:45.000 And of course, it really depends on the call. 00:43:45.000 --> 00:43:55.000 Now, after all the cooking, it's time to serve the dish. What you see here is this action of our event candidate. 00:43:55.000 --> 00:44:04.000 That's a function of the top and issue. The dots are the data, and the big short trick is to expect this function, the oscillation. 00:44:04.000 --> 00:44:09.000 So immediately you see the oscillation effect is very strong. 00:44:09.000 --> 00:44:19.000 And with all the pages back on, and this is the purely new background and these are all the others. 00:44:19.000 --> 00:44:25.000 We have very high… And the overall spectrum. 00:44:25.000 --> 00:44:36.000 with the fitted solution parameter is in the back. So when we compare the spectrum with the low auxiliated spectrum, we see the distortion. 00:44:36.000 --> 00:44:46.000 is driven by some missing parameters. Um, the background is under control, and all this. 00:44:46.000 --> 00:44:51.000 Our solution has been done mostly independent analysis group. Yeah. 00:44:51.000 --> 00:45:06.000 all the different machineries for selection, reconstruction, paper estimation, utility response, and fitting all different in these three elements of code, and then they all achieve transistence. 00:45:06.000 --> 00:45:14.000 If we look at the soil mixing parameters. The creation and comparison with other field submission. 00:45:14.000 --> 00:45:26.000 Yeah, interesting with solutions. First of all, in terms of single experiment sensitivity, our general result has an amount that is 1.6 times smaller. 00:45:26.000 --> 00:45:39.000 the previous best one. And our result is a significant improvement of standing on the shoulder of giants, of course, is better than the previous. 00:45:39.000 --> 00:45:44.000 I think it is for nature. Um, you know, measure. 00:45:44.000 --> 00:45:48.000 I'm gonna be able to give us 60 days of data. 00:45:48.000 --> 00:46:01.000 If we look at the single parameters. And their errors, we see that both parameters are already entering the percent level accuracy. 00:46:01.000 --> 00:46:06.000 What's more interesting to Matthews is that this m squared rule. 00:46:06.000 --> 00:46:14.000 One, actually. as true tools. Our result is consistent with how the. 00:46:14.000 --> 00:46:28.000 Reactive experiments, however. The same quantities can be measured by using the machines from sun, and then they consistently. 00:46:28.000 --> 00:46:30.000 You read it from the one from the reactions. 00:46:30.000 --> 00:46:38.000 So this is something interesting going on. We don't know. It's good to think about it. 00:46:38.000 --> 00:46:48.000 So at this moment, we are transiting to a precision error of ceramics and parameter lecture. 00:46:48.000 --> 00:46:54.000 In fact, we have demonstrated that such precisender for measurement is possible as long as we have. 00:46:54.000 --> 00:47:00.000 A much larger detection, and also high mass statistics. 00:47:00.000 --> 00:47:05.000 So beyond the first question, we expect to measure. 00:47:05.000 --> 00:47:18.000 Dude. sort of missing parameters, and also the data m squared C1, to enter the sub percent level accuracy. 00:47:18.000 --> 00:47:31.000 Up to 100 days of data. And for the mass quality sensitivity, suppose we have normal ordering. Then we would reach 3 sigma after 7.1 years. 00:47:31.000 --> 00:47:39.000 And if it is what it's following, then the same exposure actually will give us 0.10. 00:47:39.000 --> 00:47:52.000 The vision of journal is that. In 10 years' time, after 10 years, definitely be for 20 years, the oscillation landscape would be. 00:47:52.000 --> 00:48:07.000 So at that point, we would already know what the best product is and what's the next big focus. That will be the insurance storage. So one proposal to upgrade the genome experiment is to put. 00:48:07.000 --> 00:48:19.000 a balloon inside the central detector. And this balloon is photography neck or deluium is not decided yet. 00:48:19.000 --> 00:48:23.000 But that would be a very interesting for a while. 00:48:23.000 --> 00:48:36.000 However, for more. The observatory is designed for the next 30 years. The science, exploration includes, but as you all have seen, you have engineers. 00:48:36.000 --> 00:48:53.000 And also issues for the Earth. But we, in fact, we can also see diffusion from the sun from the atmosphere perhaps lower than also, you know, can search for BSM like the bone can. 00:48:53.000 --> 00:49:08.000 So for the solar nutritionals. the… quickest way to understand how the measuring can be done is a forum. We just specify files with the first board. 00:49:08.000 --> 00:49:16.000 I'll say, you know, it's small, you can simply put it as single. 00:49:16.000 --> 00:49:22.000 Because we don't care about the neural path flavor. So this solution basically. 00:49:22.000 --> 00:49:30.000 It comes a perfectly refined flavor oscillation. So here it becomes of the sun. 00:49:30.000 --> 00:49:38.000 The new it's produced. And it is a mixture of the mass 1 and 2. 00:49:38.000 --> 00:49:47.000 If deletion allergy is low. The investment, and this mercen population continues. 00:49:47.000 --> 00:49:56.000 To us, because it is fast, there isn't there to travel, they don't have complete or coherence anymore, they just add up. 00:49:56.000 --> 00:50:03.000 Um, independently. Therefore, we have a survival property of electoral. 00:50:03.000 --> 00:50:18.000 Like this. So, a number of, yeah. However, if we have the… high energy neutrinos from the sun. Because of the matter fact that most of the machinos will. 00:50:18.000 --> 00:50:26.000 at the surface of sun, and then again it continues to propagate. 00:50:26.000 --> 00:50:32.000 Infection. And in this case, we have survival probability. 00:50:32.000 --> 00:50:40.000 Yeah. But now the question, we talk about low energy and high energy, but how high is high? 00:50:40.000 --> 00:50:51.000 Make these two flavor solutions open. The only end step is that n squared to 1. Therefore, actually, any scale is calculated by this. 00:50:51.000 --> 00:50:56.000 When you stretch the two legions, we have this autonomy. 00:50:56.000 --> 00:51:03.000 If you can measure this function. You can measure distance. This is base ideal. 00:51:03.000 --> 00:51:08.000 So, here in Juneau, for different m squared to 1. 00:51:08.000 --> 00:51:16.000 We have different… predicted, you might say, or spectral shade, and you can see. 00:51:16.000 --> 00:51:24.000 sporting and maybe the gym? Therefore, if we can measure on a solution. 00:51:24.000 --> 00:51:42.000 This measurement can be done. This is very interesting because in one single experiment, you can measure the same basic quantity, namely someone missing parameters for objections and also for machines for the sun. This will give us direct comparison. 00:51:42.000 --> 00:51:49.000 It relates to my impact for regimes, or perhaps BSL. 00:51:49.000 --> 00:52:00.000 In addition, we are also sensitive to other. Solutional species. I mentioned that we can actually pop inside the sun here. 00:52:00.000 --> 00:52:14.000 It's very difficult. However, because the solutions are all issues, not many issues. Therefore, the reaction happens not on the hydrogen, not on the carbon. 00:52:14.000 --> 00:52:26.000 It can only happen for electron with inaccess scattering. Of course, there are other small channels at 1% rate that happening. 00:52:26.000 --> 00:52:32.000 But through the first order, the nest sketching is the major attribution. 00:52:32.000 --> 00:52:48.000 That's really… Without the IPE, for instance, in this case, it's very difficult to run. Therefore, we have to control the background to the extreme level. 00:52:48.000 --> 00:53:05.000 Well, let me come to the end and some words. So after 13 years of effort, Jimro is committed and then Romney, and the whole creation is very excited and happy, especially the younger generation, because they can actually play with the data. 00:53:05.000 --> 00:53:11.000 And the first general result is using 26 days off. 00:53:11.000 --> 00:53:17.000 data and avoid producing what it's needed for those solar parameters. 00:53:17.000 --> 00:53:24.000 And it has demonstrated. Alright, so you should. 00:53:24.000 --> 00:53:30.000 visual measurement with 20kg as a baseline 15 meters. 00:53:30.000 --> 00:53:42.000 So looking ahead, actually, what we have demonstrated is the vegetation of digital performance in terms of the energy and background control make. 00:53:42.000 --> 00:53:51.000 all these people. And some of them are actually better than this time. But the critical one. 00:53:51.000 --> 00:53:56.000 Uh, we see working live, we're working on that, and it's mostly math. 00:53:56.000 --> 00:54:04.000 So in the future, near future towards the mass bordering will be high statistics. 00:54:04.000 --> 00:54:11.000 and also optimized in terms of performance. But most importantly, the need detection. 00:54:11.000 --> 00:54:25.000 And when he stated his use, we will use this to constraint of files and provide a reference section. 00:54:25.000 --> 00:54:31.000 So instead of using that we actually can have our own native design. 00:54:31.000 --> 00:54:36.000 So, OMPO provides a language user program for the next 30 years. 00:54:36.000 --> 00:54:43.000 Okay. 00:54:43.000 --> 00:54:58.000 Thank you again. Oh, very nice of you. So we have time for questions. 00:54:58.000 --> 00:55:21.000 I was curious about the three millimeters of construction. What's the density of the liquid scintillator? How much does the detector change when you change from the water to liquid? It's lighter than water. Therefore, when you see actually… um, filming, we drink down the water and then pump it in the liquor center from above. 00:55:21.000 --> 00:55:40.000 And you embrace the important point, because… There's only maximum one, um… pressure balance point between the water and the scintinator. And then actually we have tuned like that. It is always negative pressure inside the vessel. 00:55:40.000 --> 00:55:57.000 Then we are always the water cushion inside. That R is far better for the mechanical integrity of the vessel because it's easier to go against pressure instead of against the pollution from inside. 00:55:57.000 --> 00:56:12.000 So all these mechanical stratus stressors from the acrylic vessel and also the stainless steel structure has been in the calculation and also monitor closely with the pressure sensors. 00:56:12.000 --> 00:56:19.000 So, I'm just trying to understand, does that mean that you're controlling the pressure such that it was essentially no change? 00:56:19.000 --> 00:56:37.000 I'm swapping for the logistics. Um, it's a dynamic process. We have to balance point. Eventually, it is the balance point below the ground. So there's no balance point. But when we field, we do have. 00:56:37.000 --> 00:56:53.000 To, uh, change spelling point, and then see gradually how the whole system reacts. Because if funding. When you see the strength or the lab or the ground actually changes when you fail. So it's really scary. 00:56:53.000 --> 00:57:00.000 What does it mean by eventually stabilize, and then everything is understood, I would say. 00:57:00.000 --> 00:57:10.000 So, nothing should be planned, but thanks to all these things that monitoring, we do have a gradual understanding of it. 00:57:10.000 --> 00:57:18.000 It's pretty impressive. 00:57:18.000 --> 00:57:27.000 So, uh, you pointed out that, uh, there's a, uh, tension between data from the Sun and reactions. 00:57:27.000 --> 00:57:33.000 This is solar detachment problem. So, uh, is there, like, a future plan? 00:57:33.000 --> 00:57:42.000 uh, schedule for that as well, let's see if, uh… If you can still see that tension, then the same. 00:57:42.000 --> 00:57:50.000 For this specific for this problem, the reactive part is mostly done. So what you. 00:57:50.000 --> 00:58:00.000 But then, on the other hand, Juno can also. 00:58:00.000 --> 00:58:09.000 I'm not sure if the solar neutrinos. So so… Yeah, to provide the M squared to one. 00:58:09.000 --> 00:58:16.000 And hopefully you can also shrink the airports and actually see in one experiment. 00:58:16.000 --> 00:58:34.000 What do we still have these discussions? Thank you. 00:58:34.000 --> 00:58:45.000 Yeah, any questions from Zoom? 00:58:45.000 --> 00:58:59.000 Next. So you have mentioned the possibility of supernova's something you want to optimize. How much does that influence the DAQ? 00:58:59.000 --> 00:59:12.000 We have, uh… Definitely sugar on that. So, um… 00:59:12.000 --> 00:59:17.000 It doesn't affect the current landscape is still running. 00:59:17.000 --> 00:59:30.000 But then, uh, I don't see a confliction in that, so… 00:59:30.000 --> 00:59:40.000 May I ask how these days are counted? And what is the downtime for. 00:59:40.000 --> 00:59:53.000 Um. What's the lifetime of the detector? 00:59:53.000 --> 01:00:08.000 So, um, first of all, we exclude all those tests or bad data, and then we also have the data on television runs. They are also excluded. So the remaining time. 01:00:08.000 --> 01:00:18.000 is, uh, good ones, and then we also have the DQ time defined as the physician. Yeah. So. 01:00:18.000 --> 01:00:26.000 This is how all those, uh, periods are end up together and then comes into water treatment. Nice. 01:00:26.000 --> 01:00:38.000 Yeah, the uptime is quite high, about 97. Yeah, so… Oh, yeah. 01:00:38.000 --> 01:00:45.000 On slide 15. 01:00:45.000 --> 01:01:06.000 Sorry, I haven't, um, I always have a hard time understanding this product, so you have oscillational length on the right. 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 traditional values. 01:01:06.000 --> 01:01:16.000 And that is how far the nutritional trouble from the source to the detector. There's a distance. 01:01:16.000 --> 01:01:21.000 Yeah, and then, uh, corresponding, you put the, uh… extended onto it. 01:01:21.000 --> 01:01:30.000 So the left side DEV is the… Or is the converted. 01:01:30.000 --> 01:01:45.000 HPASC becomes one, I would say, um… with this natural yield that you just converted L from N from the length to the energy. 01:01:45.000 --> 01:01:51.000 And if you, then the Juno part is the merely the. 01:01:51.000 --> 01:02:01.000 The yellow one. 52 kilometers. So this year, and then the energy, of course, several. 01:02:01.000 --> 01:02:09.000 Uh, from, uh, POM1 MB to 10MB, so there's an extension at this point. 01:02:09.000 --> 01:02:18.000 is rather small. It's between those two clients. No, no, the other client is the rendal. 01:02:18.000 --> 01:02:23.000 Right, so I'll experiment. So, for Juno is only the start. 01:02:23.000 --> 01:02:32.000 Okay, good. By the way, uh, rental car is not exist anymore. 01:02:32.000 --> 01:02:44.000 This plot is in 2020 also. Nowadays we are only talking about camera engine, but then slow plus fission also have presented solar mixing. 01:02:44.000 --> 01:02:55.000 Um, your soft phone deck, which you know, so has also sitting here. 01:02:55.000 --> 01:03:06.000 Thanks. Sorry, it just reminded me of something else you mentioned this early on, that if there were only two neutrino species, there was no concept of a normal or inverted ordering. 01:03:06.000 --> 01:03:25.000 Yeah, I was sort of curious about that. I mean… I would sort of imagine it may… could make a difference to things, whether the heavier neutrino is mostly electron or mostly beyond. If those are the two. It depends how you define things. What is the order you define things right? 01:03:25.000 --> 01:03:37.000 So you can always define one as the lightest one and have two. And in this case, you just observe what is composition of. 01:03:37.000 --> 01:03:41.000 the different flavors to one and to 2. That's all right. 01:03:41.000 --> 01:03:48.000 So the essence of the C framework of hierarchy or ordinance that. 01:03:48.000 --> 01:04:00.000 It's really to understand the definition. I'm sort of not sure that it follows with two. It's not an interesting question. 01:04:00.000 --> 01:04:11.000 measure the fractions, but… Yeah, and you make a good point. What happens if the two actually is dominated by electron? 01:04:11.000 --> 01:04:20.000 Yeah. Yeah, would you call this mass open mouth? 01:04:20.000 --> 01:04:28.000 But… 01:04:28.000 --> 01:04:38.000 Um, can I ask for your projection for the 7-year measurement, whether that is impacted by the number of. 01:04:38.000 --> 01:04:52.000 accelerators around and weather. adding a new accelerator would reduce, or… How that period could be reduced? 01:04:52.000 --> 01:05:10.000 This, first of all, is statistics from the vectors, and also the detector performance. And you remember, in order to tease out the information of the mass order, we have to see the details. 01:05:10.000 --> 01:05:21.000 That requires energy distribution, and the current projection is based on 3.1%. 01:05:21.000 --> 01:05:34.000 Uh, yeah, observing 3.4%, so still some work to do, and that actually limits our workday. On the other hand, uh, we also need to understand that on oscillated structure. 01:05:34.000 --> 01:05:49.000 This is where the top comes in. So Mr. Tao and better calibration, we could achieve this 7.1 yes, or maybe. 01:05:49.000 --> 01:05:58.000 Yeah, I think this is really exciting point about the German experiment. 01:05:58.000 --> 01:06:20.000 And, uh, yeah, just a comment. I think it's really impressive for such a short time since the… Collection of data started. Yeah. Thank you. But yes, I guess everyone is curious about. 01:06:20.000 --> 01:06:34.000 of the results function. Yes. I was also curious, I mean, the NTS wrote the picture, the whole thing is covered in the sort of some white material. 01:06:34.000 --> 01:06:45.000 One of the photographs in the 41, slide 41 looked white. 01:06:45.000 --> 01:06:51.000 Yeah. So what's this material which this is covering? 01:06:51.000 --> 01:07:08.000 Uh, first of all. This is the high density polyethylene. And this is the target. They're all diffractive. So to improve the optical separation between different parts. 01:07:08.000 --> 01:07:22.000 And also, this one can show the reactivity, stop the material coming from inside because the wall is dirty. 01:07:22.000 --> 01:07:28.000 target is something that here is actually a brand. 01:07:28.000 --> 01:07:36.000 So… but then, if there's been used in basically those experiments to use optical separation. 01:07:36.000 --> 01:07:41.000 There's no way it is produced? 01:07:41.000 --> 01:07:45.000 Well, I don't know if people buy it from China. 01:07:45.000 --> 01:07:55.000 And, uh, whatever other places? I don't know, actually. It's common to life. 01:07:55.000 --> 01:08:01.000 I think I've seen it in construction. Which country? 01:08:01.000 --> 01:08:14.000 like buildings. Because I would say this tarot is soon or have some, uh… Yeah, stocks that? 01:08:14.000 --> 01:08:24.000 is beyond some construction. For construction is just shielded dust, right? Right. Yeah, it's more than that. Oh, it's, uh, yeah. 01:08:24.000 --> 01:08:38.000 Okay. Because it has to be immersed. Yes. Okay, and let's thankful. 01:08:38.000 --> 01:08:52.000 And we hope to send that here, and also thank you very much. Please join for lunch with us. We can fake some cookies with you.
