2 CSN1 25-06-07M. Diemoz Outline PROGRESSI DA APRILE AD OGGI SCHEDULA

3 CSN1 25-06-07M. Diemoz Progressi di CMS UX: Commissioning di 4 settori DT in YB0 con cosmici completato. Installazione di EB- (18 SM ECAL su 36) completata il 22 Maggio. Installazione dei servizi di YB0 procede (ma 4 settimane di ritardo). Commissioning di HF+ completato. Primo “global run” (Lvl-1 Trigger, HF, DAQ, data transf. to T1/T2 fine Maggio). SX: Commissioning delle ruote YB- con cosmici (usando facility MTCC). YB-1 completato Tracker: acquisizione cosmici in atto. Run a T ambiente ok. Run freddo in corso (-10  C). La qualità del rivelatore si conferma eccellente. ECAL: EB- installato, ultimo SM per EB+ pronto inizio luglio. Installazione EB+ anticipata a metà luglio. 20 SuperCristalli montati su ‘Dee4’. 3500 cristalli EE consegnati (su 14750). In via di finalizzazione la schedula di consegna per l’ordine finale: ultimo xl EE a fine marzo 08. DAQ e TRIGGER: installazione in progress

4 CSN1 25-06-07M. Diemoz (NUOVA) Schedula LHC Vacuum chambers installed and baked out by end of March 2008

5 CSN1 25-06-07M. Diemoz Installazione del Magnete All magnet systems transferred to the caverns: control, vacuum, cryogenics, powering and protection. Only re-connection work between subsystems is needed. July-October: Commissioning Nov 07: Low current testing (about 400A) in the coil at 4.5K March 08: Final commissioning of the magnet ( ~ 1 week) Progressive current ramps : 3kA, 7kA, 10kA, 14kA, 17.5kA, and nominal, One slow dump at 14kA.

6 CSN1 25-06-07M. Diemoz DT Commissioning

7 CSN1 25-06-07M. Diemoz SX: DT Commissioning YB-1 SX5: YB-1 DTs commissioned using cosmics

8 CSN1 25-06-07M. Diemoz UX: DT Commissioning YB0 Sector 12 Availability of LV supplies DT: prevents simultaneous testing/ commissioning of more than two sectors at once (in different quadrants!) Prime particelle rivelate in UX

9 CSN1 25-06-07M. Diemoz DT Commissioning

10 CSN1 25-06-07M. Diemoz DT Commissioning

11 CSN1 25-06-07M. Diemoz UX: DT Commissioning YB0

12 CSN1 25-06-07M. Diemoz SX: DT Commissioning YB-1 Comunità mu in shift continuo da Aprile

13 CSN1 25-06-07M. Diemoz RPC Commissioning il pre-commissioning del rivelatore è terminato. le torri delle ruote W+1 e W+2 sono complete (cablaggio ed elettronica). le torri della ruota W0 saranno pronte in giugno. il commissioning (dopo il cablaggio) è in corso – test dei cavi e degli alimentatori di LV – test dei cavi/distributori/alimentatori HV la torre W+2 near è pronta per un test combinato RPC-trigger – il software è in fase di test. cablaggio UXC-USC è quasi finito (80%). il commissioning del sistema finale del gas inizierà a giugno. sistema centrale di LV di CMS sarà pronto per luglio 2007  solo allora sarà possibile testare il sistema finale di potenza degli RPC

14 CSN1 25-06-07M. Diemoz RPC: Problemi e novità LV-HV: circa 20 schede su 120 sono state mandate in riparazione. Statistica in fase di sviluppo. Rate uguale a tutti gli altri sottorivelatori (se non è un problema infantile ha impatto sui MOF-B). In maggio è stato scoperto un inversione sistematica dei conduttori (massa, potenza) di tutti i 480 cavi di HV (camera – PP). Errore occulto rilevabile solo con l’apertura del cavo. La ditta ha ammesso l’errore e rifarà parte dei cavi (3 ruote). Nuova schedula in atto: –2 ruote sono già state completate ed una terza sarà pronta per giugno. –Le ultime 2 ruote (W+1 e W+2) saranno aperte ad agosto e pronte per settembre. La nuova schedula comporta un grosso impegno da parte dei nostri tecnici (2 ruote rifatte da noi) e qualche spesa aggiuntiva in costi di installazione dei cavi e nei consumi. CMS sta aiutando in tutti i modi (personale) Little impact on the schedule, but additional manpower and resources needed

15 CSN1 25-06-07M. Diemoz EB- Installazione Completa 22 Maggio Test di funzionalità prima e dopo l’inserimento: difficoltà hanno rallentato le operazioni e richiesto maggiore impegno

16 CSN1 25-06-07M. Diemoz EB intercalibrazione  = 1.5%  0 in test beam 140  0 / crys  50 GeV e Cosmics Intercalibration Cross-checked in beam Tutti I SM sono stati calibrati con I cosmici

17 CSN1 25-06-07M. Diemoz EB Commissioning Services –Cooling unit in operation (was used for EB- installation on few SMs). Needs commissioning with large number of SMs and final stability. –DC- DC and AC-DC Low voltage supplies available. –Large fraction of HV supplies already in USC5. The others are still used in H4/867. Will be moved asap. –Two lasers (1 blue, 1 red) installed and commissioned at point 5 in March. Finalize cooling connections early August. Main cabling will start mid August. Each SM will be powered and tested after cabling, connected to its final VME electronics. From then on, we intend to run Barrel ECAL as continuously as possible and to join CMS global runs and cosmic runs. Will organize operation shifts: opportunity to increase the circle of specialists and train physicists to ECAL operation and DQM.

18 CSN1 25-06-07M. Diemoz ECAL EE Crystals Production: last crystals to be delivered end-Mar08 Assembly Progress 20 supercrystals mounted on Dee4  Bat 186  test beam 29 s.c. assembled for Dee1 ( ~140/Dee), 1400 VPTs glued to crystals Critical path components: HV boards, cooling bars, etc, Start mounting s.c. on Dee1 2nd week of July Schedule is very tight Ist Dee ready only at the end of 2007 (Retrofit of motherborads in SMs has had an effect on progress in EE project.) Issues Adequate manpower (to speed up assembly and for management) Work on the back of the Dee is complicated (LV cabling & looming) Concerns Limited experience so far. Much work still ahead. Will not know the exact time needed to get the last Dee until the first one has been completed and tested.

36 CSN1 25-06-07M. Diemoz CMS Commissioning Two areas : hardware/online and offline Plan to commission hardware at pit: DONE: Off-detector electronics and connection to central trigger and DAQ Full chain (front-end to data logging) tested for HCAL, planned this month for detectors connected to USC: CSC and DT LV1 trigger: all hardware components available at Pt. 5. Check of trigger functionality and connectivity ongoing and so far successful. Schedule of Detector commissioning: start commissioning slices of systems and debug functionality of all ‘components’ (front-end firmware, data-links, trigger-links, online software, databases, DQM etc) Plan of regular monthly global runs: First one end of May. Each “run” period will test increasing functionality and complexity. Also serve as milestones and synchronization points for software and computing milestones.

40 CSN1 25-06-07M. Diemoz CMS Schedule v36 Beam-pipe Closed and Baked-out by End March 2008. In v36 this point will be reached in mid-Feb 08. Major Features of v36. By end-September 07: Tracker insertion started In December 07: recording cosmics with Tracker/EB/HB etc. (Expt open) By end-March 08, CMS is closed (including pixels and one ECAL endcap) and taking cosmics with Field-ON The main uses/consequences of the new guidance: - commission the entire detector/data flow and analysis systems with cosmics data - reduce risks (e.g. by separating tracker cabling from beam-pipe installation that was previously in parallel. -Time to carry out untried operations (HF riser system in UX, pixel comm. sys.. -Open +end to allow commissioning to proceed -Repair/replace defective parts (RPC HV cables, DT fibres,… -Accommodate delay in YB0 services Tutto si sistema, basta aspettare…

41 CSN1 25-06-07M. Diemoz CMS Cosmic Runs (CCR) CMS COSMIC RUNS (CCR) meant to be stepping stones on the way to run CMS at LHC. They are meant to test for extended period of runs the consolidation of (major parts of) CMS First run (End October): Plus SIDE run. YB+1,+2 against endcap. Possibly Last chance before february/march 08 to see cosmic tracks correlated between endcaps and barrel muon chambers Second run (End November): focus on YB0 (and open +endcaps) GREM 24/30 may GREJ 25/29 June GREJ’ 23/27 July GREA 20/24 Aug GRES 24/28 Sep CCR 1 29 Oct CCR 2 26 Nov GREJ’’ 28/31 Jan GREF 25/28 Feb CCR 3 31 Mar Third run (End March 08): all CMS with magnet on Una sequenza di commissioning impegnativa che pagherà al momento di fare fisica
