1 Сессия Ученого Совета ОФВЭ, 29 декабря 2005 Проект CMS в 2005 Ю.М.Иванов

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 Направления работы в 2005 Тестирование мюонных камер в CERN (ISR, SX5) Cборка Торцевой Мюонной Системы в CERN (SX5) Тестирование электроники (ISR, bld. 904) Участие в работе физической группы RDMS

4 End-Cap Muon System 468 CSCs, not counting ME4/2 144 Large CSCs (3.4x1.5 m 2 ): 72 ME2/2 chambers 72 ME3/2 chambers Small CSCs (1.8x1.1 m 2 ): 72 ME1/2 chambers 72 ME1/3 chambers 72 ME1/1 chambers 20 o CSCs (1.9x1.5 m 2 ): 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 CSC production CSC production is finished All CSCs are at CERN CSC type Built FAST site CERN ME23/2 (US) 150/ ME2/1 (PNPI) 40/ ME3/1 (PNPI) 40/ ME4/1 (PNPI) 40/ ME1/1 (Dubna) 76/ ME1/2 (Beijing) 75/ ME1/3 (Beijing) 75/ totals 496/ / /468 (106%) (104%) (106%)

6 EMU Project Status, November 2005 CSC chamber production 496/ % On-chamber electronics 110% FAST sites (testing w electronics) 487/ % CSCs shipped to CERN 495/ % CSCs installed 360/468 77% CSCs commissioned 352 /468 75% Most of off-chamber electronics & HV production done To be finished in beginning 2006 System integration in progress, including integration with Trigger, DAQ, DCS, DQM… Recent slice test results: CSCs self-triggering working, calibration and synchronization procedures developed, data sent to global DAQ, muon tracks going through two stations registered Preparations for Cosmic Challenge in progress

7 CSC Installation (Nov 05) Installed chambers and services (w/o ME1/1) Mounting posts 720/792 91% CSC chambers 288/396 73% Skewclear cables 3672/ % LVMB (LV monitor) cables 306/396 77% HV cables (1 per CSC) 288/396 73% LV cables (1 per CSC) 279/396 71% Grounding braids (1 per CSC) 270/396 68% Gas laterals (per CSC) 216/396 59% Water laterals (per CSC) 216/396 55% All 72 ME1/1 chambers installed and tested CSC installation is ~77% complete

14 Completed ME+1/2 Station

15 YE-1 completed 15 August, 2005 YE+1 completed 3 October, 2005 Installation of ME1/1 chambers 72 chambers installed and tested

16 CSC Commissioning Use the same equipment and software (FAST-DAQ) as in production FAST sites CSC commissioning closely follows installation 288 CSC installed, 280 CSCs commissioned Frequent retests: At least every 3 months Takes care of infant mortality Long term stability Only minor problems detected

17 Future CSC Installation plans Plan to instal 18 Back ME-1/2 in Dec 05 Install 18 front ME -1/2 Jan 06 Install 36 +1/3 CSCs in February 2006 Install 36 -1/3 CSCs after the magnet test Note: All ME1/3 CSC can be installed only after corresponding RPCs are installed. CSC installation is in good shape, will be finished on schedule

18 RDMS CMS Task Force: PNPI group MC event generator HARDPING: BFKL-evolution Diffraction physics Heavy-ion physics

19 RDMS CMS Task Force: PNPI group BFKL-evolution: jets/dijets, b-quark production SM/QCD background New Physics: Quantum Gravity (Graviton/Pomeron) Diffraction physics: dijets, b-jets in DPE- and SPE-processes SM/QCD background New Physics: Higgs, SUSY Higgs Heavy-ion physics: hadron-nucleus, nucleus-nucleus collisions jets, lepton-pair production Physics: multiple rescattering, color stopping, screening, etc.
