Main goals – /06/11 4th RPC General Meeting - Pigi Paolucci 4 In priority order 1. High efficiency of the RPC data takingTC/RC 2. Assure an high quality of the dataDPG/RC 3. Clear set of results (performance and studies)DPG 4. Build the RE4 upgrade systemTC/Up 5. Enlarge the collaborationMB/IB 6. Manpower balance & budget consolidationMB/IB but this is not enough for us and we have to do more and more to improve our project….(see next slide)

More goals…… 28/06/11 4th RPC General Meeting - Pigi Paolucci 5 Main performance results: HV scan results (approved by CMS) Background (approved by CMS) System stability monitor (on-going) Study and underline all the aspects in which the RPC could play a central role in CMS: RPC use in present Muon Reco (Hyunkwan Seo) Alternative reconstruction algorithms (Min Suk Kim) Trigger studies (Warsaw and Filip)

News to underline 28/06/11 4th RPC General Meeting - Pigi Paolucci 14 Detector is running smoothly P5 and CAF crews are working very well Instruction have been improved a lot – Anna Cimmino, experts and shifters Shift reports at RC/DPG meeting OK HV P correction – ready to be tested at TS (central DCS team) # of DQM plots to be reduced in few weeks (Task forces with Anna, Anna, Alaa & Cesare) 2011 results: many approved in June Background studies: 2010 and 2011 comparison PVT: noise and DQM stored in database – ready to be used (WBM too) Simulation: improved with 2010 efficiency table Construction DB: improvements thanks to Anton and Daniela Upgrade: HLP production has been defined Gap production MoU is almost ready

What we have to improve 28/06/11 4th RPC General Meeting - Pigi Paolucci 15 Communication between TC-RC-DPG Participating to the main meetings Use the hyper-news more and more Following the official path for any new request Communication between MB and 80 colleagues People should participate to the meeting (only to the RPC RC/DPG meeting) Improve the communication between present project and upgrade Results in a public web page Put all the approved and not approved results in a common web page Improve DQM performance (reducing memory usage)

News about RPC organization 28/06/11 4th RPC General Meeting - Pigi Paolucci 16 RPC MB, coordinators and experts have access to a shared google documents used to prepare the weekly report to the XEB meeting: Very good way to share info ! June 14th: TC: Everything was perfectly stable before the gas kill on 31th May. Then after a power-cut in SG5 and a gas kill we had 5 trips in the barrel and 1 in the endcap. All have been recovered. One chamber temporarily in SG mode till next access. Trigger: Muon Trigger rate variations observed (~9%) in last weeks, the most probable reason is variation of the RPC chamber efficiency (by 2-3%) with the pressure variation (impacting the trigger efficiency in the endcaps by 3-4%, and thus the rate). Still not clear is the variation of the cluster size could impact the probability of promoting the low pt muons to high pt (impacting the rate on given threshold). Variation is not present with low PT cut (Mu0 and Mu7) and increase from Mu16 to Mu20 RC: stable since the HV scan - no problem with the new set of WP and efficiency very stable in time (2-3% of variation due to the pressure) P/T correction in PVSS has been discussed and defined and will be tested during the next TS DPG:DQM: experts are investigating in the offline DQM to speed-up it. Right now we are using 4MB and we already deleted histograms. Work is on going. MC: Comparison of number of RPC hits in Muon Reco of 2011 data with summer2011 MC, show nice agreement in barrel and endcap. Some small discrepancy in overlap region under study Upgrade: MB:

Action Items 28/06/11 4th RPC General Meeting - Pigi Paolucci HV setting with P/T correction – approved by CMS but in a human version 2. Improve history plots monitoring (current, noise, efficiency) using WBM and database 3. Include DQM trigger check in CAF duties 4. Spare components procurement 5. Long 2012shut-down plan 6. Bakelite and gap production 7. Link and Control board prototype tests at 904 (Oct-Dec)

2011 Agenda 28/06/11 4th RPC General Meeting - Pigi Paolucci 19 General Meeting:Thursday at 9:30(1 per month) DPG/RC:Thursday at 9:30(3 per month) Tech coordination:Monday at 9:00(weekly) Upgrade: Tuesday at 9:00(weekly) Management:Wed at 10:00(weekly) restricted ISR meeting:Monday 14:00(weekly) technical 904 meeting:Wed 10:00(weekly) technical GEM meeting: Tuesday 14:00(weekly) technical Upgrade RE4 Workshopto be decided Upgrade High Eta Workshopto be decided Let me ask the 4 coordinators and deputies to actively participate to the 3 weekly meetings. Unique project

Conclusions 28/06/11 4th RPC General Meeting - Pigi Paolucci 20 RPC system is running smoothly Many many nice 2011 results approved by CSM WBM is now used at CAF (noise to be included) PVT ready to use DQM and noise data Bakelite production ready to start Gap production MoU ready in few weeks
