1 00:00:00,000 --> 00:00:01,580 start when you want 2 00:00:03,440 --> 00:00:03,950 okay 3 00:00:05,990 --> 00:00:11,450 so good afternoon. Thank you for allowing me to make this presentation. I will 4 00:00:11,450 --> 00:00:14,690 present the Atlas upgrade for next years. 5 00:00:16,820 --> 00:00:17,360 Can I 6 00:00:19,250 --> 00:00:25,130 okay, I need to change the slides. So let's go on slide two. Let's start with 7 00:00:25,130 --> 00:00:32,630 the LHC and High luminosity LHC plans. At the moment we are in long shutdown two there 8 00:00:32,630 --> 00:00:37,460 are some changes on LHC essentially regarding the magnets and the injection 9 00:00:37,460 --> 00:00:42,350 system and we will have also some upgrades in ATLAS as well that will discuss Run three 10 00:00:42,350 --> 00:00:48,230 is also known as ATLAS phase one. Another long shutdown will be after run three that 11 00:00:48,230 --> 00:00:53,930 will bring us in the so called high luminosity LHC era that will see more 12 00:00:53,930 --> 00:00:59,570 improvements on injectors more protons per bunch better focusing, and an instantaneous 13 00:00:59,570 --> 00:01:07,850 luminosity up to 7.5 times 10 to the 34. We expect to collect around 3,000 inverse 14 00:01:07,850 --> 00:01:12,500 femtobarns of data. And of course, there will be some ATLAS upgrades as well. In this case, 15 00:01:12,980 --> 00:01:15,650 this upgrade um this phase is called phase two. 16 00:01:17,810 --> 00:01:19,790 So let's move on slide three. 17 00:01:21,050 --> 00:01:25,730 Let's see what is what is the impact of luminosity on the experiment essentially, for 18 00:01:25,730 --> 00:01:30,500 phase two, the requirements are that all the parts of the experiment have to stand 19 00:01:31,040 --> 00:01:36,740 at the peak luminosity of 7.5 times 10 to the 34, and to keep good performances 20 00:01:36,740 --> 00:01:42,500 at least at least as good as a run two and run three. This means to keep an 21 00:01:42,500 --> 00:01:46,700 acceptable trigger rate to keep low PT thresholds and also to mitigate the pile-up. 22 00:01:48,230 --> 00:01:53,750 We expect an average pile-up of 200 collisions per bunch. Which means 23 00:01:53,750 --> 00:01:58,820 larger event sizes higher trigger rates, higher detector occupancy readout 24 00:01:58,820 --> 00:02:05,240 limitation and reconstruction complexity. But also the detector has to stand with 25 00:02:05,240 --> 00:02:10,910 high radiation levels, which means increased radiation damage and increased activation 26 00:02:10,910 --> 00:02:19,010 of materials. Let me now show a very short summary on the main physical motivation 27 00:02:19,010 --> 00:02:23,510 for the upgrades. This is not representative of the entire Atlas physics 28 00:02:23,510 --> 00:02:28,610 program for the next year for the next phases. There are a lot of presentations 29 00:02:28,670 --> 00:02:32,510 on the Atlas physics program on the upgrades in this conference, I just noted 30 00:02:32,840 --> 00:02:40,400 some here and here. Essentially, I want to mention just that there'll be many studies 31 00:02:40,400 --> 00:02:45,560 on the precision measurements and rare decay searches on the Higgs boson. And also on 32 00:02:45,560 --> 00:02:49,580 the Standard Model processes the study of rare decays like the search for the Higgs in two 33 00:02:49,610 --> 00:02:54,800 muons, and also the search beyond Standard Model that may be concentrated for 34 00:02:54,800 --> 00:03:00,380 example on exotics and susy programs and also dark sectors. Let's move on slide five. 35 00:03:02,300 --> 00:03:06,830 And so, we start talking about ATLAS phase one upgrades these are the upgrades 36 00:03:07,730 --> 00:03:11,870 that I will discuss and this is also the these are also the locations in the 37 00:03:11,930 --> 00:03:18,080 detector. Let's move with the new small wheel detector on slide six. The new small wheel 38 00:03:18,080 --> 00:03:24,470 is a made of two five meter radius wheels in the Endcap region covering the 39 00:03:24,950 --> 00:03:32,270 region of eta between 1.3 and 2.7. Each wheel is formed by two external small thin gap 40 00:03:32,300 --> 00:03:36,050 chambers TGC wedges that are used mainly for trigger for bunch crossing 41 00:03:36,050 --> 00:03:41,360 identification and for vector tracking. And internally they have two micro megas 42 00:03:41,360 --> 00:03:45,830 wedges, which are used mainly for tracking with a spatial resolution less 43 00:03:45,830 --> 00:03:53,000 than 100 microns. On the right top you see the layout of the two wheels uh the 44 00:03:53,000 --> 00:03:58,280 For the large and small sectors, the chambers are built in Institutes in four different 45 00:03:58,280 --> 00:04:02,540 continents. This gives you an idea of the huge effort that the experiment has put in 46 00:04:02,540 --> 00:04:06,500 this project. And which is the aim of the new small wheel, the aim is to reduce the 47 00:04:06,500 --> 00:04:10,700 fake muon triggers in the Endcap region by making a coincidence between the existing 48 00:04:10,700 --> 00:04:15,920 detector, which is the big wheel. And the new small wheel. You can see it here in this 49 00:04:15,920 --> 00:04:20,810 plot in the right middle, where you see some tracks and some particles that are that can be 50 00:04:20,810 --> 00:04:24,500 rejected by using the new small wheel system. Essentially, if you have these three 51 00:04:24,500 --> 00:04:28,670 tracks, you can trigger only on the A track while you can take out the 52 00:04:28,670 --> 00:04:34,250 tracks like B which produces only hits in the in the big wheel. And also tracks like 53 00:04:34,250 --> 00:04:38,930 the C where you have hits in the big wheel and new small wheel but with the, with 54 00:04:38,930 --> 00:04:43,460 the track, it's not pointing in the to the interaction point towards the interaction 55 00:04:43,460 --> 00:04:48,380 point. So maybe that's been produced by some other kind of direction. On left 56 00:04:48,380 --> 00:04:52,850 bottom, you also see the trigger readout schema for the new small wheel system. It's a 57 00:04:52,850 --> 00:04:57,770 very complicated schema. Electronics is also based on many custom boards custom 58 00:04:57,770 --> 00:05:03,560 elements. The schema goes from the front end here. On the on the left to the off 59 00:05:03,560 --> 00:05:08,270 detector right. There are four custom asics developed for the system for the 60 00:05:08,270 --> 00:05:11,720 front end. There are many front end boards. There are boards sitting on the 61 00:05:11,720 --> 00:05:16,760 rim of the wheel this one reported in the pink box. And there is also off detector 62 00:05:16,760 --> 00:05:23,870 electronics which is essentially based on ATCA modules. On slide seven, let's move 63 00:05:23,870 --> 00:05:29,330 on the new small wheel status. The, about chambers and electronics for the first 64 00:05:29,330 --> 00:05:35,030 wheel, on Side A. They’re already produced and are on track also for the second. And 65 00:05:35,060 --> 00:05:39,470 indeed, many electronics parts have already completed their production the integration 66 00:05:39,470 --> 00:05:45,080 activities are in full swing for both for Micromegas and for sTGC. As you can see 67 00:05:45,080 --> 00:05:51,560 in the pictures on the left. When I say integration I mean assembly installation 68 00:05:51,560 --> 00:05:57,740 connections but also software for DAQ and triggers as well they’re being developed 69 00:05:58,190 --> 00:06:03,890 prior to COVID break it was on track for installing the first wheel before the 70 00:06:03,890 --> 00:06:11,900 end of the year. And but you may see here in the bottom right that the two sectors are 71 00:06:11,930 --> 00:06:17,030 already installed on the wheel since March. Let's move on the other on another 72 00:06:17,030 --> 00:06:20,240 upgrade on slide eight, the BIS seven eight upgrade. 73 00:06:21,590 --> 00:06:26,810 We just saw that new small wheel will cover a region in eta between 1.3 and 2.7 74 00:06:28,460 --> 00:06:32,990 while the big wheel covers a region between one and 2.7. So, there is an intermediate 75 00:06:32,990 --> 00:06:37,970 region between one and 1.3 that is not covered by the new small wheel. And 76 00:06:37,970 --> 00:06:42,710 this region is only partially covered in the large sectors by the existing so called 77 00:06:42,740 --> 00:06:49,550 EIL4 TGC endcap chambers. So the idea of the experiment was to install the 78 00:06:49,550 --> 00:06:54,530 decision was to install new detectors in the BIS region. So only in the small sectors in 79 00:06:54,530 --> 00:07:01,760 order to reduce the foreseen fake rate. This upgrade is made of 16 RPC chambers with 80 00:07:01,760 --> 00:07:07,400 that are thin gap RPC triplets with one millimeter of gas gap instead of two and new 81 00:07:07,400 --> 00:07:17,330 front end electronics and also, the existing 16 MDT detectors will be replaced 82 00:07:17,330 --> 00:07:22,910 with small MDTs that are drift tubes with diameter of 15 millimeters instead of 83 00:07:22,910 --> 00:07:29,450 30. And the detector production is ongoing As you may see on right picture photo, the 84 00:07:29,450 --> 00:07:37,880 this is an RPC triplet in BB5 site and also the installation of the A side in principle 85 00:07:38,180 --> 00:07:43,760 was scheduled to be done by summer maybe this is still the case while the C side is 86 00:07:43,760 --> 00:07:47,510 postponed uhm Yes, the C side installation is postponed until long 87 00:07:47,510 --> 00:07:51,980 shutdown three. This is also an important project, which is a pilot project for 88 00:07:51,980 --> 00:07:58,010 phase two because the same MDT and RPC detector technology will be used when the 89 00:07:58,040 --> 00:08:04,430 barrel inner layer will be equipped. Let's move on slide nine, the upgrades on the 90 00:08:04,460 --> 00:08:09,320 liquid argon calorimeter and level one calo trigger system, there will be new front 91 00:08:09,320 --> 00:08:14,990 end and back end boards for the calorimeter. These will allow to increase 92 00:08:15,020 --> 00:08:19,130 the trigger tower granularity and have a good trigger performances even at the high pileup. 93 00:08:19,130 --> 00:08:23,930 So this is the granularity for run one and run two and this is the new granularity for run 94 00:08:24,440 --> 00:08:30,050 three. The aim of course is to keep a low trigger rate thanks to the background 95 00:08:30,050 --> 00:08:35,240 rejection and low thresholds thanks to the high geometrical resolution which is 96 00:08:35,240 --> 00:08:40,700 increased about the level one calo trigger and readout system. You can see the full 97 00:08:40,700 --> 00:08:49,220 schema here on the bottom right. There are three posters on these on these items on 98 00:08:49,220 --> 00:08:53,990 next Thursday and essentially the main feature are the new feature extractor 99 00:08:53,990 --> 00:08:59,330 boards, the electron jet and global that process the data from the 100 00:09:00,290 --> 00:09:06,020 electromagnetic calorimeter at a higher granularity. And in this case they will 101 00:09:06,020 --> 00:09:10,550 perform more refined processing with respect to the previous runs, and also to 102 00:09:10,550 --> 00:09:16,250 have a better discrimination between photons, the electrons taus and jets. Of 103 00:09:16,250 --> 00:09:22,820 course, you can find many more details on these three projects about slide 9 ehm 10. 104 00:09:24,230 --> 00:09:28,550 About the full TDAQ phase one upgrade. As I said, there will be an upgrade on the 105 00:09:28,550 --> 00:09:29,480 level one calo. 106 00:09:31,030 --> 00:09:34,750 There will be also an upgrade on level one topo, which is a new board that performs 107 00:09:34,750 --> 00:09:39,610 topological algorithms on data coming from calorimeters and muons in the end cap 108 00:09:39,610 --> 00:09:45,580 region. There will be the new sector logic board endcap sector logic board it will 109 00:09:45,580 --> 00:09:49,360 receive inputs from the new muon detectors. That's why we need a new board. 110 00:09:50,380 --> 00:09:55,300 New detectors are the new small wheel muon system and the RPC BIS and also inputs 111 00:09:55,300 --> 00:10:01,480 from the outer layer of the tile calorimeter the extended barrel of tile calorimeter there will 112 00:10:01,480 --> 00:10:07,420 be also poster on this on next Thursday and all these inputs will be used in order 113 00:10:07,420 --> 00:10:11,260 to reduce the fate rate in the endcap as I already said about the central trigger 114 00:10:11,260 --> 00:10:16,660 processor new muon to central trigger processor interface boards will be built. 115 00:10:17,080 --> 00:10:20,530 These will manage the data transfer from the new boards. So essentially from 116 00:10:20,530 --> 00:10:26,800 Level one Topo and new endcap sector logic I already discussed and also will have more 117 00:10:26,800 --> 00:10:33,430 resources in order to process data and higher bandwidth to be tran uhm by using 118 00:10:33,460 --> 00:10:38,350 optical links essentially about readout system. There will be the new Felix 119 00:10:38,350 --> 00:10:42,820 readout system it acts like a router between the custom front end links and 120 00:10:42,820 --> 00:10:47,200 commercial, multi gigabit network technology. In order to transfer data to 121 00:10:47,200 --> 00:10:51,730 the appropriate destination. It interfaces with the timing trigger control TTC system and 122 00:10:51,730 --> 00:10:56,200 the busy system. It will be used in phase one for the upgrades I already described. 123 00:10:56,440 --> 00:11:01,450 The new small wheel BIS seven, eight and the liquid argon upgrades but we’ll be also the 124 00:11:01,450 --> 00:11:07,570 standard system for the phase two for run four, okay. So, we are ready to move 125 00:11:07,570 --> 00:11:15,100 to phase two. These are the items I will discuss, and their position in the experiment. 126 00:11:15,370 --> 00:11:22,780 The first is new all silicon inner tracker also called ITK. The current ATLAS inner 127 00:11:22,810 --> 00:11:28,210 detector was designed to operate for 10 years at the luminosity of 10 to 34 at an 128 00:11:28,210 --> 00:11:34,840 average pile up of 23 and the level one rate of 100 kilohertz Of course using it at the 129 00:11:34,840 --> 00:11:38,860 high luminosity LHC era will bring increased occupancies and bandwidth saturation 130 00:11:38,920 --> 00:11:44,740 and also radiation damage. And so for this reason, a new all silicon tracking system 131 00:11:44,740 --> 00:11:51,100 has been designed. It's made of two subsystems the strips which cover a region 132 00:11:51,130 --> 00:11:58,150 in eta up to 2.7 which is made of four barrel layers and six endcap discs and the pixel subsystem 133 00:11:58,180 --> 00:12:03,580 which covers a region up to eta four and is made of five barrel layers plus 134 00:12:03,580 --> 00:12:09,820 inclined modules plus barrel and endcap rings the aim of ITK is to reach equal or better 135 00:12:09,820 --> 00:12:13,300 performance than the existing detector in a much more difficult tracking 136 00:12:13,300 --> 00:12:18,220 environment. And for example, to keep a high track reconstruction efficiency 137 00:12:18,280 --> 00:12:24,880 and low rates of fake tracks. Just to give you some numbers on slide 13, I want to 138 00:12:24,880 --> 00:12:29,470 give you some numbers and photos. To give you an idea about the huge ITK project the pixel 139 00:12:29,470 --> 00:12:35,470 have more than 10,000 modules more than 33,000 front end chips more than 10 to 140 00:12:35,470 --> 00:12:43,240 nine channels, and also strips have roughly 10 18 Ks modules and almost 60 millions of 141 00:12:43,240 --> 00:12:49,990 channels. These are some photos or some designs of how the project is evolving. 142 00:12:51,130 --> 00:12:57,550 Let's move on slide 14. About liquid argon calorimeter. The current electronic is not 143 00:12:57,550 --> 00:13:01,690 compatible with phase two requests essentially for latency and trigger rates 144 00:13:01,690 --> 00:13:06,100 as we will see later. And also the radiation requirement for Phase Two are 145 00:13:06,100 --> 00:13:12,070 above the original design. So the idea is to keep the phase one upgrade boards, but 146 00:13:12,070 --> 00:13:18,760 also build the new front end and back end electronics. In order to read the detector 147 00:13:18,760 --> 00:13:24,580 at full granularity, and send the data off detector to the back end at 40 megahertz. 148 00:13:26,110 --> 00:13:29,440 There's a poster on this. There was also a presentation today about the 149 00:13:29,440 --> 00:13:36,190 high granularity timing detector HGTD it will be used to mitigate the pileup. And so, to 150 00:13:36,220 --> 00:13:41,080 use high precision timing information to distinguish between collisions, it will be 151 00:13:41,080 --> 00:13:46,060 installed in a space between the inner detector and the calorimeter endcap so 152 00:13:46,060 --> 00:13:52,270 essentially in this zone and it will be based on silicon low gain avalanche 153 00:13:52,300 --> 00:13:56,920 detector technology that will be used also by CMS. And with the timing 154 00:13:56,920 --> 00:14:02,050 resolution less than 50 Pico seconds it will improve the forward object reconstruction 155 00:14:02,050 --> 00:14:06,910 by complementing and helping the tracking capabilities of ITK in the forward 156 00:14:06,910 --> 00:14:10,810 region essentially, but we’ll be also used for online and offline luminosity. 157 00:14:12,470 --> 00:14:18,380 Let's move on slide 15. Another calorimeter the tile cal It's made of steel plates 158 00:14:18,380 --> 00:14:23,090 and plastic scintillator tiles for the phase two upgrades a complete replacement 159 00:14:23,090 --> 00:14:27,260 of on detector and off detector electronics is foreseen because of mainly two 160 00:14:27,260 --> 00:14:34,880 reasons radiation damage and aging and but also to be compatible with the TDAQ 161 00:14:35,750 --> 00:14:39,350 requirements, new architecture requirements and transfer the full data off 162 00:14:39,350 --> 00:14:46,550 detector optically at 40 megahertz. Moreover, the roughly 10% of the photo 163 00:14:46,580 --> 00:14:52,970 multipliers, the ones reading out the most exposed cells will be replaced the uhm 164 00:14:53,000 --> 00:14:57,980 is foreseen an upgrade of low voltage power supply and also the high voltage distribution 165 00:14:57,980 --> 00:15:04,550 system. And this is the full acquisition schema for the tile cal and the project is in 166 00:15:04,550 --> 00:15:08,570 a very mature state and preproduction is expected already this year for several 167 00:15:08,570 --> 00:15:16,940 subsystem. Thanks. Let's move on the muon detectors on slide 16. Just to 168 00:15:16,940 --> 00:15:20,270 give you an overview of the system the upgrades foreseen for the muons have two 169 00:15:20,270 --> 00:15:24,680 main objectives to reduce the trigger fake rate in the barrel and the end cap region 170 00:15:24,710 --> 00:15:28,880 and to increase the geometry coverage in the barrel. In order to do this new 171 00:15:28,880 --> 00:15:35,870 detectors will be installed in the barrel the RPCs plus sMDTs so if you look 172 00:15:35,870 --> 00:15:42,830 at two pictures on the bottom, on the left for the small sectors, the old BIS MDTs 173 00:15:42,830 --> 00:15:47,870 will be replaced with the new small MDTs plus RPCs exactly like the BIS 78 174 00:15:47,870 --> 00:15:53,930 project while in the large sectors. The new RPC detectors will be mounted on top 175 00:15:53,960 --> 00:15:59,780 of the existing BIL MDTs, because here we have a much more space also in 176 00:15:59,780 --> 00:16:07,580 the end cap region, the TGC EIL four detector will be replaced. At the moment 177 00:16:07,580 --> 00:16:11,870 there is a doublet there will be a triplet in order to allow more robust coincidence 178 00:16:11,870 --> 00:16:19,100 algorithm. Please note also that for the small sectors there are the coil support 179 00:16:19,100 --> 00:16:24,020 structures here that create coverage holes in the barrel middle layers as it 180 00:16:24,020 --> 00:16:28,130 has been for run one and run two and it will be also in run three. And so these coverage holes 181 00:16:28,130 --> 00:16:35,300 will be covered by these new layer of RPCs. Let's move on slide 17. For the level zero 182 00:16:35,300 --> 00:16:41,240 muon trigger. So, the data from the RPCs TGC and the new small wheel detector 183 00:16:41,240 --> 00:16:46,580 used in Phase One will be complemented with the new detectors with BI RPCs with 184 00:16:46,580 --> 00:16:49,310 the EIL4 TGCs with the tile cal 185 00:16:50,960 --> 00:16:53,000 tile calorimeter outer cells and with the small MDTS 186 00:16:54,280 --> 00:16:58,240 By looking at the top left plots, we obtained two objectives essentially we are 187 00:16:58,240 --> 00:17:02,170 covering all the regions in eta. So, essentially we are increasing the 188 00:17:02,170 --> 00:17:10,120 geometrical acceptance on the barrel from 78% to 95%. And we can also reach an increased 189 00:17:10,120 --> 00:17:15,880 selection efficiency in in reducing the fake triggers by making more robust 190 00:17:15,880 --> 00:17:20,980 coincidences. In order to do this also the muon detectors boards will be designed 191 00:17:20,980 --> 00:17:25,780 and installed they will allow full digital detector readout. So the data will be sent 192 00:17:25,780 --> 00:17:30,310 off at 40 megahertz sent off detector. The bottom block shows the trigger readout 193 00:17:30,310 --> 00:17:34,900 schema for the muon spectrometer, the barrel and endcap new off detector sector 194 00:17:34,900 --> 00:17:40,240 logic. Will perform the trigger algorithm as usual. But now the system takes the 195 00:17:40,240 --> 00:17:44,980 advantage from the higher latency and so also the MDT trigger processor is used will 196 00:17:44,980 --> 00:17:49,330 be designed and used in order to help in mu identification and fake trigger rejection and 197 00:17:49,330 --> 00:17:54,790 as I said that readout data are then sent to Felix Once the event is accepted and 198 00:17:54,790 --> 00:17:55,180 validated 199 00:17:57,020 --> 00:17:59,900 let's move on slide 18, the TDAQ system in phase two. 200 00:18:01,340 --> 00:18:02,270 This is a very 201 00:18:03,950 --> 00:18:08,810 short overview. In the picture, you see what is called the baseline schema for the 202 00:18:08,810 --> 00:18:12,350 TDAQ. It's a two level architecture. The first level is the level zero where the 203 00:18:12,350 --> 00:18:17,390 central trigger processor receives two minutes thanks receives data from the muon 204 00:18:17,390 --> 00:18:23,030 system and calorimeters for Level zero level zero muon. It issues a level zero accept signal 205 00:18:23,060 --> 00:18:27,650 which is the pink arrow which is sent back to the detectors and then data are read out 206 00:18:28,100 --> 00:18:33,260 by the inner tracker the calorimeter and the muon system to Felix. The second level is 207 00:18:33,260 --> 00:18:39,260 an high level trigger HLT. And here It is made of processor farms, a custom hardware called 208 00:18:39,260 --> 00:18:45,890 HTT that uses the tracking data to refine the trigger algorithm. The trigger rate has to be at 209 00:18:45,890 --> 00:18:52,070 one megahertz It was 100 kilohertz in run 1 and run 2 the latency has to be less than than 10 210 00:18:52,070 --> 00:18:56,300 microseconds. it was 2.5 microseconds in run one and run two and the permanent storage has to be 211 00:18:56,300 --> 00:19:00,380 performed at 10 kilohertz, under consideration is also level zero level one 212 00:19:00,380 --> 00:19:05,450 architecture which will allow to scale system later if it is required by the physics 213 00:19:05,690 --> 00:19:12,230 requirements or by the LHC hm HL-LHC performances, but the system has to be 214 00:19:12,230 --> 00:19:17,150 designed Now, in order to allow also an evolution. Let's just focus on the level 215 00:19:17,150 --> 00:19:22,220 zero architecture. there will be additional data from calorimeters and from 216 00:19:22,220 --> 00:19:27,020 muons for the level zero calo together with the new phase one upgrades these three 217 00:19:27,170 --> 00:19:30,980 there will be also another which is called the fFEX or forward features 218 00:19:30,980 --> 00:19:35,960 extractors. For the muons The data from new small wheel will be also complemented with 219 00:19:35,960 --> 00:19:42,290 the data from the MDTs and also for the rpcs to improve the trigger coverage 220 00:19:42,290 --> 00:19:47,240 and efficiency. A new system will be the global trigger that will perform offline 221 00:19:47,240 --> 00:19:53,510 like algorithms on full granularity on calorimeter data. It will make use of 222 00:19:53,540 --> 00:19:57,500 topological criteria such as clustering, or photon and electron identification and 223 00:19:57,770 --> 00:20:02,540 isolation, for the central trigger the muons to Central trigger interface designed 224 00:20:02,540 --> 00:20:07,490 for phase one will be used also for phase two only the firmware will be upgraded while 225 00:20:07,490 --> 00:20:10,760 the new central trigger processor will be developed and designed for phase two 226 00:20:12,430 --> 00:20:16,660 about the DAQ and high level trigger the detector readout will be done at 1 megahertz 227 00:20:16,750 --> 00:20:17,230 which is ten times 228 00:20:18,920 --> 00:20:21,590 time is over this is my last This is my last slide 229 00:20:23,180 --> 00:20:28,130 the readout throughput will be to be 5.2 terabytes per second which is 20 times more than today's 230 00:20:28,640 --> 00:20:33,920 the DAQ system will be based on Felix the data flow will make buffering event building 231 00:20:34,280 --> 00:20:38,540 and recording data and also the event filter as I said is based on hardware track trigger, 232 00:20:38,930 --> 00:20:43,970 which is based on the associative memories or FPGAs. And these are my conclusions So, 233 00:20:43,970 --> 00:20:48,080 essentially the large data set that can be collected will allow to perform a lot of precision 234 00:20:48,440 --> 00:20:54,020 measurements both in the exploration of standard model and rare standard model processes 235 00:20:54,020 --> 00:20:59,810 and for new phenomena, the phase one upgrades and phase two are Well ongoing phase one is 236 00:20:59,810 --> 00:21:03,950 already almost completed and ready for installation while phase two upgrade is in 237 00:21:03,950 --> 00:21:10,100 the prototype state design state. If you want more details here, I put a link with 238 00:21:10,100 --> 00:21:14,030 all the published TDRs. Thanks. Sorry for being late. 239 00:21:14,720 --> 00:21:20,210 Okay, thank you Vincenzo. Thank you for this rather extensive talk. I'm sure there must be 240 00:21:20,210 --> 00:21:20,930 questions. 241 00:21:23,000 --> 00:21:24,260 Remember to raise your hands 242 00:21:34,460 --> 00:21:38,930 there are no question. I want to ask you one thing I didn't get. Yes. So what is the status 243 00:21:38,930 --> 00:21:42,770 now for the new small wheels of the micro mega detectors, what is the status of the 244 00:21:42,800 --> 00:21:43,490 installation? 245 00:21:44,930 --> 00:21:50,120 Okay, the micro megas and also the TGC, the full new small wheel system, was a high 246 00:21:50,120 --> 00:21:59,630 priority task. So even during the CERN COVID crisis say there was a task force 247 00:21:59,630 --> 00:22:05,780 that was still working on the assembly and installation and connections, even when 248 00:22:05,780 --> 00:22:10,400 the number of people allowed to enter CERN was very low. Then since last 249 00:22:10,400 --> 00:22:13,400 week I think much more people entered. 250 00:22:15,560 --> 00:22:16,850 I'm not sure 251 00:22:18,290 --> 00:22:25,400 if the ehm if another sector was installed, so the idea is to install more uhm first the small sectors 252 00:22:25,790 --> 00:22:33,080 like these two and then the largest. But of course if you want if you ask about micro 253 00:22:33,080 --> 00:22:39,170 megas, micro megas has to be sandwiched with the TGCs. So it's a 254 00:22:39,170 --> 00:22:45,350 matter of having everything at CERN and then to put everything back together to 255 00:22:45,350 --> 00:22:50,930 make the all this stuff that I tried to put pictures here and then install on the 256 00:22:50,930 --> 00:22:58,280 wheel. I think that there was not too much delay on the new small wheel because it was 257 00:22:58,280 --> 00:23:04,460 a high priority task. I don't know much more details in reality. Okay, thanks. 258 00:23:05,870 --> 00:23:07,130 So time for one question.
