  1. Muon Piquet Report week 26 Oleg Maev, 04.07.2011

  2. 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

  3. 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

  4. MD: Oleg Maev, 04.07.2011

  5. 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

  6. 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

  7. 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

  8. Electronics: Oleg Maev, 04.07.2011

  9. HV status: Oleg Maev, 04.07.2011

  10. Some statistics on new tripped gaps Oleg Maev, 04.07.2011
