Muon Piquet Report week 26 Oleg Maev, 04.07.2011
Monday, 27.06.2011Fill 1900:Number of bunches per beam = 1237Number of colliding per beam = 1152Integrated Delivered Lumi (1/pb) = 21.20Integrated Recorded Lumi (1/pb) = 19.42Peak Inst Lumi (10^30/cm^2/s) = 379.85Average Inst Lumi (10^30/cm^2/s) = 295.71Average Mu = 1.35Average Pileup = 1.83Average L0 Physics Rate (kHz) = 539.58Average HLT Physics Rate (kHz) = 2.33Efficiency Per Fill (percent) = 90.63Annual Cumulative Efficiency (percent) = 89.44Longest fill and a new record on Integrated LumiRichard played a bit with high Lumi . Random throttling on MUTELL1s has been observed. In General Muon was fine. Only two new tripped Gaps. Oleg Maev, 04.07.2011
Tuesday, 28.06.2011Fill 1901:Number of bunches per beam = 1380Number of colliding per beam = 1296Dumped at ~16:00. == > MD started.Unfortunately, online services (operation plots and Fill summaries) are unavailable still, so I can’t present the numbers.Muon was Ok. Two new tripped Gaps. Oleg Maev, 04.07.2011
MD: Oleg Maev, 04.07.2011
MD: Set of noisy thresholds have been tuned and implemented in the DAQ recipe. Tested without beam. After every physics fill we’ve got more noisy channels. Oleg Maev, 04.07.2011
Technical Stop • OPEN : Monday 4th • UX85B: Survey done by LHCb RP team • expected supervised area: green light to access probably at ~11h00 • END OF DETECTOR WORK: Thur 07 pm • UX85 CLOSURE : From Friday 8 am • Magnet power converter tests at nominal current
Plan and status : 1. RDBs replacement – done 2. MWPC conditioning with negative polarity – prepared 3. Studying of electronic problems – started 4. Global threshold scan - ? TS: Oleg Maev, 04.07.2011
