Hope all or some of them will be here next year as well. Underlined who are here. Marcos Correa Martins will stay at CERN until beginning of Februrary

What we have at CERN We got all 1760 PMT’s after they were measured and sorted at Iowa. BB’s 134 out of 216 (needed) at 904 lab. All are populated with PMT’s 79 BB’s housing 632 PMT’s tested so far in a two dark boxes. Test’s are going on 12 BB+PMT assembly is tested in a week LS1 session, December CMS week3 Independent DAQ – CMSHCAL11, Crate with one DCC and two HTR’s FE – 12 HF style QIE’s, CCM, Cbox – enough to connect 3 ROBOX’es – 1/3 of a quadrant. All these will be moved to P5 when time comes

What we have at CERN - PSU CAEN SY4527 mainframe – next generation after SY2527 A1538 for cathode+A1511B for last two dinodes For final installation there will be different A1538D module used, which is a modification of A1538 and provides 10ma per channel LS1 session, December CMS week4 A1538D A1511B SY4527
5
At P5 LS1 session, December CMS week5 Work is based on units of Quadrants (1/4 or 90degrees of one HF). Size of smallest HV “partition” (commissioning unit) Smallest unit that can be cabled independently

ROBOX Rework -Basic concept LS1 session, December CMS week6 Work is pipelined ~4 Weeks/HF quadrant, +3 Days contingency at end of each quadrant ROBOX work is ~3/4 the effort of the assembly team Disassemble boxes Rebuild boxes 1-3 Remove boxes from quadrant (9 boxes) Reinstall quadrant (9 boxes) Rebuild boxes 4-6 Testing contingency Rebuild boxes 7-9 Test boxes 1-3 Test boxes 7-9 Test boxes 1-3 Disassemble boxes Test boxes 4-6 Testing contingency Rebuild boxes 1-3 Assembly team Testing team Installation team 1 week Remove Qn+1 Slide from Ianos Schmidt
7
Cabling work -basic concept LS1 session, December CMS week7 Cabling work ~1/4 the effort of the assembly team. Cabling work in shadow of ROBOX testing, but, Cables should be tested and bundled by the time ROBOXes are ready for installation. Prefer to have cables installed after ROBOX installation. Rebuild boxes 1-3 Rebuild boxes 4-6 Testing contingency Test boxes 7-9 Test boxes 1-3 Disassemble boxes Test boxes 4-6 Testing contingency Rebuild boxes 1-3 Assembly team Testing team Installation team Remove Qn+1 Install Cables Reinstall quadrant (9 boxes) Rebuild boxes 7-9 Remove Cables Cable Prep and testing Install Cables Reinstall quadrant (9 boxes) Remove Cables Commissioning Cable Prep and testing Slide from Ianos Schmidt Test boxes 1-3

LS1 session, December CMS week8 A LS1 Startup scenario Learning curve: Installation team 100% on ROBOX work. No overlap with cable prep. Takes longer to cable first quadrant - Impact is on start of commissioning (Catches up about half way through). Disass emble 1-3 Install 4-6 Cont. 7-9 1-3 Disass emble 4-6 Delay from late cable PO -Assuming Order placed Nov 30,2012, expect cable available ~April 11, 2013. -expect delay to be ~2 Weeks Remove boxes from Q1 HF in garage Feb 26 First cables at CERN DELAY Start of LS1 (Feb.11, 2013) Cable prep. Cable Install Commissioning On detector work: Modify metallic structures, Consolidate services, install cable support… Assembly team Testing team Installation team Central services (cooling, power) Available end of April Local DAQ available ~20 May Slide from Ianos Schmidt

Summary LS1 session, December CMS week9 All PMT’s and more than a half out 216 BB’s are at CERN B904 lab. Rest is expected to be at CERN by end of February All BB’s are populated with PMT’s, around 80 BB’s are tested, others waiting their turn. Testing speed is 12 BB’s per week. Expect to end 904 test by late March. Then setup moves to P5 alcove. By then first set of ROBOXes already could be removed and lifted up to surface. ----------------------------------------------------------------------------------------------------------- HF work is organized around units of “quadrants”, which represent ¼ of one HF. There are three teams working in parallel: Assembly team, responsible for ROBOX rebuilding, and cable preparation Testing team, responsible for ROBOX testing and test data analysis Installation team, responsible for ROBOX and cable installation, as well as cable/service consolidation, and rack/cable support modifications.. Each team spends ~4 weeks on a quadrant. Work is pipelined, so one quadrant takes ~6-7 weeks to complete. Expect first HF to be complete ~Mid August 2013 Expect second HF to be complete ~End December 2013
