but this is not enough for us and we have to do more and more to improve our project.(see next slide)More goals28/06/114th RPC General Meeting - Pigi Paolucci5Main 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)28/06/114th RPC General Meeting - Pigi Paolucci6

Background position ? News to underline28/06/114th RPC General Meeting - Pigi Paolucci14Detector is running smoothlyP5 and CAF crews are working very wellInstruction have been improved a lot Anna Cimmino, experts and shiftersShift reports at RC/DPG meeting OKHV 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 JuneBackground studies: 2010 and 2011 comparisonPVT: 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

News about RPC organization28/06/114th RPC General Meeting - Pigi Paolucci16RPC 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 Mu20RC: 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 TSDPG:DQM: experts are investigating in the offline DQM to speed-up it. Right now we are using 4MB and we already deleted 4.000 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 studyUpgrade: MB: News about RPC organization28/06/114th RPC General Meeting - Pigi Paolucci17Shared google calendar with meetings and vacation (Pigi and Gabriella) please ask to be included in the listMinutes provided by all the coordinators thanks a lot XEB and XEC minutes circulates in real time MB and FB minutes and news in a week All info sent to Group Leader (we ask to circulate)Action Items28/06/114th RPC General Meeting - Pigi Paolucci18HV setting with P/T correction approved by CMS but in a human versionImprove history plots monitoring (current, noise, efficiency) using WBM and databaseInclude DQM trigger check in CAF duties Spare components procurementLong 2012shut-down plan
