  1. Muon Piquet Report week 38 Oleg Maev, 26.09.2011

  2. LHC performance Oleg Maev, 26.09.2011 Good week for LHCb: Delivered Lumi - ~87 pb-1, Recorded Lumi - ~ 82 pb-1 And no serious problem in MUON!

  3. Summary of calibration test of Dialog signals width. Oleg Maev, 26.09.2011 1. Width in M5R4 ~ 21.5 ns: FILL 2140 - 6,89 pb-1 (Threshold tuned a bit on C-side) https://lblogbook.cern.ch/MUON/2747 2. Width in M5R4 ~ 18 ns: FILLs 2144 and 2147 - 7,44 pb-1 (Threshold tuned a bit on C-side) https://lblogbook.cern.ch/MUON/2752 https://lblogbook.cern.ch/MUON/2760 3. Width in M5R4 ~ 15 ns: FILLs 2150 and 2152 - 8,02 pb-1 last run in fill 2152 with width=3 r.u. was 102324 (Threshold tuned a bit on C-side in fill 2150 only) https://lblogbook.cern.ch/MUON/2769 https://lblogbook.cern.ch/MUON/2772 Finally we took 5 fills (22,35 pb-1). Always we had several very noisy channels in M5CR4

  4. MWPC’s status from HV-side Oleg Maev, 26.09.2011 Only one new Gap affected during last week

  5. DQ issue: https://lblogbook.cern.ch/Data+Quality/5428 Oleg Maev, 26.09.2011 I couldn’t find any problem in M4R1, but M4Q3R4 was out of time during this fill probably due to huge noise on CMB M4C1C. All runs affected! Finally, it seems we can flag this run as OK. FILL 2103 - M1 removed from data taking

  6. New low efficient region in M5Q4 Oleg Maev, 26.09.2011 Visible since 17.09.11
