Took place in Siena
STFC-RAL-CR03: last September.
STFC-RAL-CR03: So this is how I structured it. So I start with useful notes. So for chlorine on the idea, the conference where it is location, etc. Then I present a few selected presentation. They cover different topics.
STFC-RAL-CR03: and finally, some summary and personal conclusion and impression from from the conference.
STFC-RAL-CR03: As I said, initial notes. So for chlorine. So where is Sienna? Siena is in Tuscany, Italy, and I'm 50 kilometers south of Florence. You can see here.
STFC-RAL-CR03: Originally it was an ancient Etruscan settlement until it was taken over by the Romans around third century BC.
STFC-RAL-CR03: And it was renamed. Hence the name Sienna. Nowadays it's important growing Middle Ages until it became a town municipality in 12 century, and the since then it Floyd. For around 2 centuries it had frequent confrontation with the neighboring town, so the time were fighting each other.
STFC-RAL-CR03: play it extensively until eventually it was taken over by Florence in sixteenth century. That's the reason why you see most of the buildings, from an architectural point of view, in seeing a kind of being frozen at that period of fourteenth century.
STFC-RAL-CR03: So an example, a few example, are shown here. Okay, this is the Piazza and Campo. which dates back again to fourteenth centuries. Practically the heart of the city is the location of the ancient Roman Forum.
STFC-RAL-CR03: and surrounded by beautiful fourteenth century lofty buildings. By the way, this is the place where the famous horse race. The panel is takes place twice a year.
STFC-RAL-CR03: and another beautiful
STFC-RAL-CR03: building is a the dwarf again, going back to fourteenth century, which is one of the best Roman or Gothic architectural example.
STFC-RAL-CR03: It includes inside works by Pizano, Donatello and Pinturicu, and also depicted on the floor. There's an interesting
STFC-RAL-CR03: project that goes back to an Domini 1,300, which really seems to be a kind of relating the idea of people detector, you can see
STFC-RAL-CR03: impressive for the time.
STFC-RAL-CR03: and then you walk around. You see, this is typical
STFC-RAL-CR03: scenery that you see when you walk around the city really retains a very much medieval atmosphere. This is a view from the Basilica de Santa Mexico. This is the auto deity, which is a very well preserved medieval garden.
STFC-RAL-CR03: They still had the same herbs and stuff and layout they had in medieval times. And, by the way, this is where we had the conference dinner
STFC-RAL-CR03: right going to the conference now. So this was the sixteenth topic of seminar on innovative particle and radiation detectors. And the it's a developed, it developed over a time span of 40 years, and that's always been devoted to detectors and experiments normally on high energy particle physics.
STFC-RAL-CR03: The previous, I mean the original workshops took place in San Miniato, which is a little town around 50 kilometers northeast of Siena until 2,002. Since then they always had conferences held in Siena.
STFC-RAL-CR03: Last edition took place 4 years ago, because of covid 2,019. And this seminar is focused on well. this is an extra from the website. So UN advanced technologies in particle physics, etc., etc., literally covers everything which revolves around detectors and associated electronics. And there are also participants of industry.
STFC-RAL-CR03: Right? The main topics covered are listed here, as you can see, it's quite extensive. So tracking detectors, colorimeters, moon tomography, neutrino detectors read out electronics, etc., etc. The attendance is normally limited to approximately 150 under 50 people. So I put in these 2 histograms here. They're quite interesting, because first, they showed that the ratio between talks and participants is almost ideal.
STFC-RAL-CR03: You can see 98 talks and 129 participants. Previous edition. It was primarily one.
STFC-RAL-CR03: So that means that most of the people hold that which is good.
STFC-RAL-CR03: and the top is to actually show essentially topics covered in this edition a kind of uniform. If you thought for these resonance peak here, you probably don't see currently, but it's actually peaked at the fast timing sensors.
STFC-RAL-CR03: They didn't say the same thing 40 years ago. Kind of interesting. You see, for example, tracking detectors seem to be more emphasized at the time, whereas now
STFC-RAL-CR03: and time in detectives seem to be kind of very popular. So
STFC-RAL-CR03: what about the pixel of timing? Say, where does it, Pixel? The timing?
STFC-RAL-CR03: Well, there's probably still covid in tracking here, as I say sometimes the way they classify the talks is a little debatable, but in a case, as I said, II count the the number of toes they had on this specific topic, and I noticed that was a kind of quite evident peak.
STFC-RAL-CR03: And so, as I said, another diversified range of topics covering detectors all sort of application. I found the the technical level of them, most of the talks and posters quite high.
STFC-RAL-CR03: and I selected a few presentation from from this conference. The first 2 are related to fast time, you know, before, but also because we actually, when they we presented something in this respect.
STFC-RAL-CR03: So that's why I thought it was important to show also our contribution. The other 2 are solar nutritional detector, immune tomography and archaeology. Something
STFC-RAL-CR03: don't know too much about it. But I found it interesting enough to show them to you today.
STFC-RAL-CR03: Okay, so the first one is actually what we showed there, and not because it was the best, but certainly certainly because I think it was interesting, but also because I think it's important to show what we shown in this respect with regard to the peak.
STFC-RAL-CR03: the interesting topic. So this is the characterization of these low gain avalanche detectors that we design a fabricated using 39 E. 2 E. Process.
STFC-RAL-CR03: So very briefly, the reason why we want to do that and time for high ruminology. Tlc is shown here and summarized so denominator luminology to the Lsc. And we have the number, the average number of Pb. Interaction
STFC-RAL-CR03: approximately 23. But eventually we will go from a scenario like that one here on the left
STFC-RAL-CR03: today, 20 year on the right. So the increased windows, if essentially we increased the pilot, and that would make.
STFC-RAL-CR03: It's very difficult to
STFC-RAL-CR03: do the track reconstruction.
STFC-RAL-CR03: and this becomes particularly important, particularly critical at Ieta when the resolution degrades and eventually becomes larger, and then the average distance between the vertices. So one way to surprise the effect of the pile up is to try to do that. A construction to separate the vertices
STFC-RAL-CR03: also, using time discrimination rather than simply increasing the spatial granularity, granularity of the sense, and according to simulation of time, resolution of the order of 30, because second per track seems to be adequate
STFC-RAL-CR03: with this in mind, that the high granularity timing Detector Hgtd
STFC-RAL-CR03: in Atlas has been designed, and this plan to be implemented here.
STFC-RAL-CR03: The Atlas detector in the gap ranges between the barrel and the encamp calorimeter. Similar system, of course, would be implemented in the Cms. Detector
STFC-RAL-CR03: and in Atlas. It will consist of 2 instrumented double-sided layers on 2 cooling supportings on each of the 2 end caps here listed on this table
STFC-RAL-CR03: summary of the specification required for this Hgtd and I like the specification required the specification for the sensor, which is that one we developed. So the log gain avalanche detectors. I don't know if you can read the specs, but in any case the time specification are 30 pico, second per track.
STFC-RAL-CR03: which correspond to approximately 35. Because I compare it before irradiation. And then, well, yeah, the specs are listed here, and also there's a link provided here that says it's all.
STFC-RAL-CR03: So the time is sensory, as I said, is based on this login avalanche detector technology. So what is it? Very briefly, I mean, on the left we have a PIN diode, a cross section of PIN dial.
STFC-RAL-CR03: and on the right we have a cross section of this elgat sensor. The main difference between the 2 is that elg got sensor replace, gain layer, which normally consists of a very thing layer of bottom
STFC-RAL-CR03: don't silicon under the collecting well of the Catholic when properly biased and proper aged. Of course the bias applied to this traction makes the internal electric field
STFC-RAL-CR03: increase up to a point where we ignite impact organization, at least to charge multiplication. And this is a key thing in order to increase the time resolution of the same sort.
STFC-RAL-CR03: So we
STFC-RAL-CR03: designed in collaboration with this terrifying semiconductor foundry, based in Uk, and 2 plans of fabrication. Of this I got sense of the first one, the layout of which is shown here
STFC-RAL-CR03: was actually meant to be a sort of test ranks in order to investigate what we could achieve using the technology provided by them. This is a picture of the first wafer we got obviously went through different type of simulation.
STFC-RAL-CR03: and this is actually a picture of the layout and one of the fabricated devices. From the second run of fabrication we did with teledy, which is actually aimed at the Hgtd, so it has the right size, the right the right layout, you can see a picture. It consists of 15, like 15 cells of 1.3 by 1.3 square millimeters.
STFC-RAL-CR03: and of course it uses different the level of doping, though the game day, in order to cover in order to optimize its performances.
STFC-RAL-CR03: So we went through a number of ticket simulations in order to minimize the uncertainties arising from incorrect knowledge of the doping profile, and so on. We also compared our simulation with the Sims.
STFC-RAL-CR03: but I sold
STFC-RAL-CR03: and the okay. So I won't go
STFC-RAL-CR03: through all this. But really, just to show you the, for example, the simulation that we need also predicted the effect, like gain suppression, that you have in these devices when the density of charge is high, and that the essentially suppressive internal activity field and reduces the game.
STFC-RAL-CR03: and we did some tests, mostly at Oxford, using the set up here shown on the left. And also we did some test here in lab 9 in Dpd, using the setup that I set up here, and which is essentially a fast laser that also allows you to cool down the sensor to minus 20 degrees if you want to test here again the sensors
STFC-RAL-CR03: and we got resulted of summarized here. So for different type of flavors. So these devices. We get the gain as a function of the bias voltage that is the order of tens, or approaching even 100 for non-related sensor, and the the interesting plot to look at. One of the interesting plot to look at is that on here at the bottom, right shows again normalized with respect to the individual breakdown voltages of each individual device.
STFC-RAL-CR03: and also compare the results with a decat simulation. I mean, very briefly, we could get good metric between decat simulation and test results up to around 80% of the breakdown. Beyond that the results diverge. But up to 80%.
STFC-RAL-CR03: That is also pretty good.
STFC-RAL-CR03: Okay. So this plot also summarize the timing characteristic we obtain from our sensor, and in summary using photons we can achieve a time resolution which more properties jitter the order of 10 ecosystems
STFC-RAL-CR03: when using particles. We didn't do that. But our collaborators in Birmingham started doing this test. We can achieve something like 30, 35 ecocyron style resolutions.
STFC-RAL-CR03: Again, following the data essential.
STFC-RAL-CR03: we haven't tested the idea censorship, but certainly within the specs required for
STFC-RAL-CR03: and Nct.
STFC-RAL-CR03: right? So this is basically the summary conclusion phot talk which essentially says what I just said. So the simulation met so well up to 80% what we measured from real devices. And we got the measure, the jitter of the order of 10 ecosystems and oops.
I hope.
STFC-RAL-CR03: and then around 30, because I couldn't use chant. But people.
according.
STFC-RAL-CR03: what is the difference between faultless particles? Well.
STFC-RAL-CR03: so that clearly affects quite a lot by a factor of but these take a 3 3.5.
STFC-RAL-CR03: Your time. Resolution with 4 times is much better. That's why you can get something like 10%, 10 people. Second. which are particles 3, 35 microseconds. That depends also on the thickness and thickness of the sensor. But
STFC-RAL-CR03: with this type of sensor that are 50 micron, you had that
STFC-RAL-CR03: good.
STFC-RAL-CR03: Let's see if it works
STFC-RAL-CR03: right. The second talk still covering this topic, I chose it because he's
STFC-RAL-CR03: and certainly among the best, if not the best, of what I've seen in terms of timing same sort. So these are being presented by Yakubu University of Geneva. And he talked about the Monolith project so towards picosecond timing, using monolithic Cico. So the idea is quite advanced. So basically, they try to propose a monolithic sensor that has these very very good, excellent
STFC-RAL-CR03: timing capabilities, and also and we shall see, seems to be also very so the project itself developed over period of several years. What they presented actually relates to the last 2 submissions of the monolith prototype, 2,
STFC-RAL-CR03: which is essentially a matrix of 12 by 12 pixels or not square for a number of reasons. And maybe you can see a better picture here.
STFC-RAL-CR03: Well, not much better. But in any case, so the interesting thing to note is that, as I said that this chip has the pixels
STFC-RAL-CR03: again, as I said, exact on pixels, not square. And also they read out electronics integrating the same chip. The technology is not 0
STFC-RAL-CR03: the city from Germany and the and we shall see some of the slides. I think these the key for the very good performance if they showed so. These iteration they were talking about did not have again leave. So, strictly speaking, it's just the PIN dial is not a log gain ambulance detector.
STFC-RAL-CR03: So why they optimize in this iteration is the resistivity of the pitaxial layer. So that increased. And of course they read out electronics.
STFC-RAL-CR03: So there is some tests that serve using under 20 biomes. And then but I can't get him talking
STFC-RAL-CR03: entertainment. But anyway, so
STFC-RAL-CR03: so well, obviously the result, they're gonna show you I'm gonna show you, really, are really interesting because they show results per it, not per track, because the setup they showed are they single device under this other number of these devices.
STFC-RAL-CR03: And nonetheless, they claim that time is a solution of the order of 20 gigose, using charge particle
STFC-RAL-CR03: as we hopefully able to see later on. And that time resolution increases as a function of the power density.
STFC-RAL-CR03: So yeah, you can see exactly the plot that was talking about.
STFC-RAL-CR03: So, as you can see here at the time. Resolution for this monolith prototype, 2
STFC-RAL-CR03: nice
STFC-RAL-CR03: gets better as a function of the power density that tells us you can see here that it's all 20 picosecond or 2.7 watt per square centimeter, which is quite impressive. Given that these is just a couple to some very fast.
STFC-RAL-CR03: Why is that? Well, obviously, because they without electronics, because it's faster. As I said, they use it in German.
STFC-RAL-CR03: But they actually proved that just using a sufficiently fast electronics, you can achieve this time resolution. For from me.
STFC-RAL-CR03: simple bean diet, I don't see there is anything more interesting to show you before. Okay, well, just plots showing.
STFC-RAL-CR03: So without game day, they can achieve this.
STFC-RAL-CR03: Now this plot is interesting because they were showing as a function of the fluids. So data these devices up to, as you can see, 10 to the 16, one mev neutron equivalent.
STFC-RAL-CR03: a
STFC-RAL-CR03: influence. These monoliths, too, and apparently the time resolution they got still using charge particle from strontium. 90
STFC-RAL-CR03: is still of the order of 46 picoseconds, and is very high fluids. I mean, this included the fluence. We have a high luminosity that at sea pixel level so
STFC-RAL-CR03: quite tied. and the
STFC-RAL-CR03: which is a kind of more or less acceptable. What to me is a little
STFC-RAL-CR03: difficult to accept is, they claim deficiency which, since the old. quite tight for a device here needed to this level of fluids.
STFC-RAL-CR03: But in a case. So that's what they claim. So time, resolution on the order of 40 picoseconds for devices heavily that this fluids, using this technology, which is again without gain data. So just a PIN dial coupled to a silicon Germanium without electrons.
STFC-RAL-CR03: they were also showing these novel.
STFC-RAL-CR03: They call it pico ad sensor concept. That is essentially an gun. So it does again they give. But instead of being close to the end, well at the top
STFC-RAL-CR03: is actually embedded, buried in the epitaxial.
STFC-RAL-CR03: So they got that apparently from ISP, which is a foundry based in Germany, and the
STFC-RAL-CR03: that he explained a bit, not in great detail, how they could achieve this. And but the key thing is really to have the gain data embedded in the sensitive region, such that in principle you can uniform gain throughout the entire structure. Not that's limited to the pixel is
STFC-RAL-CR03: okay, so they need some test. And well, these are some of the some I see were showing. So you can see, here's a function of the yeah of the power. They can claim something like well down to 70, which is quite good again, using charts particle.
STFC-RAL-CR03: And of course there are still some issues, as you can see here, for example, as a function of what the particle hits your hexagonal sensor. You have a degradation in the tiny solution, but still it's quite good. I mean, they go from something like 30 picoseconds at the pixel center up to 25 picoseconds at the pixel edge, which is still
STFC-RAL-CR03: quite impressive, anyway.
STFC-RAL-CR03: And yeah, this is a summary from this talk. So this Eco had novel
STFC-RAL-CR03: elgat sensor has been optimized according to what they're saying. Probably they're trying to improve
STFC-RAL-CR03: essentially, this game uniformity and should be back from foundry. Well, now.
STFC-RAL-CR03: right? So these are the 2 first talks I mentioned. As I said, they were covering the topics of fast timing. The last 2 I chose are this one which is called solar, our future liquid Argon, Dbc. To detect the Meb scale, and unless somebody has some question on the first talks.
STFC-RAL-CR03: Right?
STFC-RAL-CR03: So this was given by Sorry by Jan Kuzmann from University of Bern, and the idea is to develop and
STFC-RAL-CR03: a time projection chamber that has also the capability using a pixelated and plane to basically do a better threed reconstruction.
STFC-RAL-CR03: the possible new trainers interacting deliberate medium.
STFC-RAL-CR03: So the concept itself is not do what is practical. The same concept. It was originally proposed by Ruby in 1977. But of course, exploiting the modern technology. They will try. They are trying to
STFC-RAL-CR03: basically embed in the anode plane that pixelated the structure that allows one to perform such collection. And also the and photosensor, sensitive to the UV light emitted by the recommended
STFC-RAL-CR03: electrons in the ionized the Argon atoms. So why they want to do that well, well, the detection of solar Htp neutrinos is clearly the main thing. But obviously, if you look at the typical Pb reaction
STFC-RAL-CR03: I used producing new neutrinos, but with a cut of energy quite low. That is really challenging, because the cross section really is very, very much reduced. That is a low energy on neutrinos.
STFC-RAL-CR03: And of course they're also trying to exploit these technologies for additional studies and noble detectors content, and perhaps to implement it in due or other other same sort. What is, I say? The cross section of a gallery. So the flavor you consider all the type of interaction drops quite significantly at low energy.
STFC-RAL-CR03: and again they list what they want to achieve. An excellent energy, resolution, threed detection, and the
STFC-RAL-CR03: tagging, the Nutrino flavors and so on.
STFC-RAL-CR03: So the prototype
STFC-RAL-CR03: they fields.
STFC-RAL-CR03: because that's sending
STFC-RAL-CR03: that one's thick.
STFC-RAL-CR03: Nope on the cable or something.
STFC-RAL-CR03: Think it's one
STFC-RAL-CR03: interesting
STFC-RAL-CR03: to the cable.
STFC-RAL-CR03: But anyway, so
time.
STFC-RAL-CR03: right? Okay, so I'm trying to. Okay. So they built a few prototypes of these structures. So you can see here they they the 3 prototypes, the first one consist of
STFC-RAL-CR03: a series of stack, PCB. Or smaller size. You can see here they had this pixelated PCB. On which they embedded is a UV detectors that are silicon photo multiplied, and the this the first prototype, the second prototype, is slightly bigger, and they want to go for a demonstrator of large scale demonstrator that possibly is going to be used up
STFC-RAL-CR03: so, and it has a well cubic meter sized.
STFC-RAL-CR03: So they did some simulation, you know, to understand there are some issues in terms of uniformity of drift field. When you had this pixelated analytic, and that's also the Cdc. Conformer on it.
STFC-RAL-CR03: and apparently not so. They discussed at length how they needed.
STFC-RAL-CR03: And okay, they described also the the test of the first prototype emerged in a prior seat, or it's well, when is immersing liquid. And here they were showing some results, some tracks
STFC-RAL-CR03: and presumably from cosmic. And that's right. Okay, so say they also showed some tests of the second prototype, which is, say, just scaled up version of the first one
STFC-RAL-CR03: immersed in a cariostat.
STFC-RAL-CR03: Okay? And these are the results. They go from the second prototype. So they were able to do a 3D. Reconstruction of this particle. So the concept of having this pixelated anode and this embedded civic photo multiplier seems to be working.
STFC-RAL-CR03: and, as I said, the idea is obviously to explore these solutions will allow them to do solar ner detection, and perhaps to implement this somewhere in you.
STFC-RAL-CR03: I the last talk. I don't know if I have time. I just wanted to.
STFC-RAL-CR03: Okay. So unless there are questions on this talk, I'll move on to the last one, and which I found very interesting, which is essentially minimum demography for
STFC-RAL-CR03: archaeological applications. And
STFC-RAL-CR03: how does the threshold compare with what's currently planned
STFC-RAL-CR03: threshold of protection and so forth.
STFC-RAL-CR03: I don't recall it. They showed that killed, and
STFC-RAL-CR03: they showed in terms of. They described at length, for example, the simulation here just put a slide.
STFC-RAL-CR03: What they were doing in order to understand. If there were some distortion of the drift field in the structure they proposed.
STFC-RAL-CR03: and they described the length of the day efficiency and the fact. They were no cross talk, but the result they were showing, or mostly cosmic, this one. So this tracks
STFC-RAL-CR03: from the furthest that necessary people to die for.
Okay.
STFC-RAL-CR03: in. I think it's probably would make it if they collected all the time. Probably the first one would be the same.
STFC-RAL-CR03: Yeah, you're right, because I think these, as far as annoying is, is not it's not the 2 old phase, just that kind of canonical. So basically, you and you interacting. And then there are
STFC-RAL-CR03: the UV photos, and then head items that you are able to collect the signal.
STFC-RAL-CR03: So.
STFC-RAL-CR03: anyway.
STFC-RAL-CR03: right as I said, the last talk is related to this new one, tomography, application, and this talk was given by delete.
STFC-RAL-CR03: Well, certainly. yes. from University of Birmingham.
STFC-RAL-CR03: and the idea is to use the concept of new demography to investigate the archeological sites that are plenty. Probably now in Italy, also in that area.
STFC-RAL-CR03: And okay. So here they describe obviously the concept itself that you may know it goes back to Alvaris when seventies, I think they first used this concept to investigate
STFC-RAL-CR03: the possible prices of feedage. And one of the great data meets. And they built this detector. They had this detector, which is actually better show.
STFC-RAL-CR03: And in another slide. First, okay, let's describe what they wanted to do. There are, as I said, a number of archaeological sites in Italy, and especially in the day in Peru, not too far from Sienna, that are still unexplored. So they choose this one, which is a site I never heard of. To be honest, but
STFC-RAL-CR03: any case seems to be interesting. You can see this section here on the left is that on the which is open to the public, and that one here on the right is a
STFC-RAL-CR03: partly unexplored. So there are some tumblers they discovered that they use as a reference, of course, because they are void. So they can basically use that as a reference as of a new on transmission.
STFC-RAL-CR03: And they wanted to investigate that are other possible cavities that could
STFC-RAL-CR03: hide some treasures from the past in this section here.
STFC-RAL-CR03: So okay, so this is like a map of the region. And this is a picture of this that they use as a reference. So they also discuss that the father they took some samples, they the stones inside. They came. In order to use the density, the average density of the material, use it again to compensate for the for the new tomography they did.
STFC-RAL-CR03: and this is a picture of the muon tracker
STFC-RAL-CR03: that they used is essentially a queue of 50, I think, by 50 by 50
STFC-RAL-CR03: is cubic centimeter, and
STFC-RAL-CR03: it's obviously a 3 Xy planes that has arranged the photo multiplier.
STFC-RAL-CR03: I mean scintillator sensor, of course, arranged in an Xy plane with photo multipliers at both ends
STFC-RAL-CR03: in order to make their response to the scintillating line more uniform and is portable so you can move it around. It's a relatively heavy issue or so, and something like 50 to 60 kg. But then you can move it around. You can collect data for a while, and then eventually they do
STFC-RAL-CR03: the offline analysis. And this is the area they investigated in this Etruscan
STFC-RAL-CR03: historical
STFC-RAL-CR03: region. So these are some of the plots they were showing. So I believe that. like difficult to see, but the
STFC-RAL-CR03: alright okay. So the X axis represent the azimuth and the Y axis, presumably the altitude, and they were able to obtain enough that actually showed here in correspondence to these reference thumb.
STFC-RAL-CR03: the expected increase in neuron transmission. And they also described
STFC-RAL-CR03: some optimization they did, taking into account. The
STFC-RAL-CR03: changes in transmission due to the process of vegetation in this region so quite impressive overall and the right. So, using all these offline analysis, they were able to identify, subtracting how the effect potentially due to the vegetation differences in density of the stones in that area
STFC-RAL-CR03: potential area of interest. They could perhaps have these unknown cavities inside the
STFC-RAL-CR03: mount it.
STFC-RAL-CR03: So they also apply the technique that allows you to to basically obtain a 3 dimensional reconstruction from the from the view on tracks.
STFC-RAL-CR03: And
STFC-RAL-CR03: essentially, I think there is a reference here. If the size of the detector is compatible to the actual distance of the device or the
STFC-RAL-CR03: the
STFC-RAL-CR03: object that you want to investigate, you practically apply an algorithm which is similar to a stereoscopic vision. So basically, you look at the same thing from 2 slightly different perspectives, and using that, you are able to do a kind of 3D. Reconstruction of
STFC-RAL-CR03: the object itself, and apparently the concept works, because you can see here they were able from the
STFC-RAL-CR03: from the mule demography.
STFC-RAL-CR03: to reconstruct this reference standard
STFC-RAL-CR03: in 3D.
STFC-RAL-CR03: In the end. As I said, they identify the potential interest regions. In these
STFC-RAL-CR03: you can see, he highlighted in this Etruscan settlement
STFC-RAL-CR03: that are potentially having some
STFC-RAL-CR03: caverns chambers in it, and they assume that if this is the case, there should be some entrances close enough to where this chamber should be. So they started some investigation with the help of some archaeology, and apparently they found some entrances to these cavities, and the the next step is clearly to
STFC-RAL-CR03: to obviously get funding
STFC-RAL-CR03: from the agency that would allow deeper and more thorough investigation of this
STFC-RAL-CR03: of these cavities.
STFC-RAL-CR03: And it's also the the conclusion, essentially what I just said. So they they apply this technique to a number of archaeological sites, and they also develop this back projection technique that allows you to do a 3D. Reconstruction
STFC-RAL-CR03: from the new tomography and the the concept. The approach ceased. Work. As I said, they identified the potential interesting region is a transcan settlement, and they found evidence of some cavities that are now waiting to be explored.
STFC-RAL-CR03: So.
STFC-RAL-CR03: And that's a concludes my last presentation. So these are my personal conclusion on this
STFC-RAL-CR03: idea. 23 conference. And I said overall, it was a very good conference with many interesting talks. As you've seen, they covered a wide range of different topics, so not only related to particle physics, but literally the same new tomography. There were also quite a few talks on the
STFC-RAL-CR03: and medical to symmetry, medical imaging solar neutrinos.
STFC-RAL-CR03: others it was very difficult to classify to be honest, but
STFC-RAL-CR03: in the case quite interesting. So it's a very interdisciplinary approach with the title for different applications.
STFC-RAL-CR03: The location is excellent, I forgot to mention, but I'll do it now, and very super catering so is actually one of the few conferences is not the only one I've been
STFC-RAL-CR03: where they actually said the afternoon sessions
STFC-RAL-CR03: a little difficult to attend. But anyway and finally, the proceeding I actually published in the Journal of Instrumentation. So it's it's a good good journal.
STFC-RAL-CR03: So yeah, thank you.
STFC-RAL-CR03: too good. Other questions.
