  1. Piquet Report 29.08.2011 E. Furfaro

  2. Luminosity summary Not luminosity this week… …just finished to collect luminosity by FILL 2040 started on Monday: about 21/pb acquired. LHC sent to MD state at the very beginning of the week. It was decided no more collisions for physics in LHCb.

  3. LHCb details 22 Aug: Beam dump about 18:00 (Fill 2040) , Fill is back in the evening; 23 Aug: Lost our Twiki pages, logbook etc.: back at noon with the message on logbook “After few attempts to inject over the night, the machine switched to MD”; 24 Aug: During last night we took runs in TAE mode, LHC in MD; 25 Aug: As the plan was less than clear from LHC, HV were switched OFF, LHC in MD; 26 Aug: We are Still OFF, LHC in MD; 27 Aug: We are Still OFF, LHC in MD; 28 Aug: Still OFF till 17:00: turned ON and went to READY for TAE runs. TAE runs started about 20:00 and finished about 22:30 then HV OFF again, LHC in MD; 29 Aug: LHC technical stop, accesses for interventions plan from today;

  4. TAE runs overview FILL 2047, Runs: 100387 to 100403 About 9x10^6 events

  5. TAE runs overview FILL 2058, Runs: 100668 to 100675 About 20x10^6 events

  6. HV tripped gaps 13 gaps now under training (4 A-side and 9 C-side) + 5 permanently OFF. 3 less respect to last week.

  7. Station selection Monitoring Panel Single chamber can be selected or deselected by left mouse click Just debug text box By these buttons you can select/deselect regions you want or the whole station

  8. Monitoring Panel • Color list: • Green: all FEBs reachable • - Red: at least 1 FEB not reachable Right mouse click opens the corresponding chamber panel This chamber has one FEB not reachable By clicking this button you can check if FEBs are present or not.

  9. Monitoring Panel Color list: - Green: no FEB, no channel noisy - Orange: at least 1 channel noisy - Red: at least 1 FEB noisy and in case noisy channels New rate counter added by Davide Shows the results of rate count by coloring the chambers A tooltip with FEB or channel noisy appears by positioning the mouse over a chamber
