  1. Сессия Ученого Совета ОФВЭ27 декабря 2006 Проект CMS в 2006 Ю.М.Иванов В.В.Сулимов

  2. ПИЯФ в CMS В проект вовлечены • Лаборатория физики элементарных частиц ОФВЭ • Лаборатория мезоатомов ОФВЭ • Группа экзотических ядер ОФВЭ • Отдел мюонных камер ОФВЭ • Отдел радиоэлектроники ОФВЭ • Отдел вычислительных систем ОФВЭ

  3. CMS

  4. End-Cap Muon System • 468 CSCs, not counting ME4/2 • 144 Large CSCs (3.4x1.5 m2): • 72 ME2/2 chambers • 72 ME3/2 chambers • Small CSCs (1.8x1.1 m2): • 72 ME1/2 chambers • 72 ME1/3 chambers • 72 ME1/1 chambers • 20o CSCs (1.9x1.5 m2): • 36 ME2/1 chambers • 36 ME3/1 chambers • 36 ME4/1 chambers • Frontend Electronics: • 170K Cathode channels • 140K Anode channels • Trigger&DAQ • (on-chamber part) • Alignment&Services

  5. CMS

  6. PC commissioning on + Side MTCC

  7. Statistics of electronics boards on installed chambers Board type/on_US_CSCs/total/replaced CFEB/1764/2124/22 LVDB/360/432/6 LVMB/360/432/7 CSC/360/432/4 AFEB/10152/11448/2 ALCT /360/432/5

  8. Summary of replacements • 5 boards had mechanical damages: • LVDB – broken input connector • LVMB – broken switch • ALCT – broken input connector • CFEB – broken latch, input connectors • 20 CFEBs were replaced: • 14 CFEBs – dead channels, low response to the test pulse, no comparators, no data, … • 6 CFEBs - by mistakes • 5 LVMB – read wrong currents • 5 ALCT: • four boards had 1.8 V fuse burnt out • one board couldn’t been readout • 9 cables: • one DMB-LVDB was damaged • eight skew clear cables • 4 CSCs: • two chambers couldn’t hold HV > 2.7 kV • two chambers had unacceptable level of noise

  9. HV long term test stand at ISR

  10. CSC: MTCC  START-UP

  11. ME+4 ME+3 ME+2 ME+1 CSC Scope at MTCC

  12. Online Event Display CSC/DT–GMT–GT trigger integration, with Global DAQ readout CSC–CSC/TF–GMT–GT triggered event Run 4593#52618 Ilaria Segoni, Dan Holmes, et al. CSC+DT triggered event (using GMT+GT)

  13. More Event Displays … • 3 CSCs: strip digis (yellow), wire digis (magenta), Segments point correctly but are a bit small to actually see • Barrel DT segment (red) and digis (green) • Barrel RPC digis (cyan)

  14. MTCC  START-UP: Event Display

  15. Missing dowel pins on YE+3 (back, blue arrows) and YE+2 (front, yellow arrows)

  16. Missing dowel pins on YE+3 Damaged CFEB cover on ME+3/2/27 due to falling pin

  17. Missing dowel pins on YE+2 Damaged CSC ME+2/1/13 (top) and ME+2/2/27 (bottom) due to falling pin

  18. MTCC  START-UP: Mechanical installation and cabling Need UXC55 schedule!

  19. YE+3 prep

  20. YE+3 lowering 30th November Tower to shaft distance ~7cm Overall lowering time ~10h

  21. YE+3 landing in UXC55

  22. YE+2 lowering12th December

  23. YE+2 landing in UXC55
