<- Back to Run Coordination Meetings:Fall2018 Run


Monday, Nov 5 at 08:45

  1. Notes from Friday & weekend:
    • Friday
      • Email from PD that the recovery time on Tuesday will probably only be 4h.
      • Sasha started work on PS field studies at 2pm (from 1pm to 2pm mostly no beam). Will return later or tomorrow to finish these.
      • ComCAL humidity sensor alarmed, Sasha Nick & Vlad made a short access to deal with this, found the sensor was bad.
      • Hovanes found new best collimator x from beam scan.
      • Found Jay's suggested quadrupole change improved focus slightly, keeping with that
      • Overnight: good production running
    • Saturday
      • Smooth running continued until 2pm cryo temp trouble, down for 4h
      • Sasha looked at CCAL trigger during downtime and finished up the PS field studies (with beam)
      • Overnight: mostly smooth production running. Time-travel went without a hitch (transition to DST).
    • Sunday
      • RF issues ~8am, 4h down + some shorter outages
      • Swing shift more steady, overnight MCC quad problem 1.5h, otherwise ok
    • Trigger Spreadsheet
  2. Issues
  3. Reports
  4. Plans
  5. Notes
    • css_new is an option Only now I remember this
    • Low E measurements to go ahead
    • Reminder to extra-check monitoring after work in the hall.

  1. Last 24h
    • active collimator scan done. The intention was to make sure that the beam was centered on the collimator and then decide whether to ask for beam convergence adjustment but the results were confusing and we decided to continue running without changes for now.
    • Mark filled both alcohol bubblers
    • Sasha looked at BCAL LED trigger timing - hopefully this is fixed
    • Production - beam trips quite frequent
    • Cleared up some mysteries from yesterday - a network issue was the cause of the beamline counters switching off. It should have triggered an alarm but didn't. And the TagM mess was indeed when the DAQ config was set to cosmics.
  2. Issues
  3. Reports
  4. Plans
    • Production
    • Monday beam studies 0830, ~ 4h ; Tues recovery ~ 8h
    • Tentative plan for V-wire TAC run on Wed next week at 2 PS settings, nominal & lower Eg. Then follow with low Eg test runs. Maybe a 3rd TAC run after the low E data-taking.
    • Q on whether to go ahead w second set of 7GeV test runs - need collaboration agreement
    • Remember to make a plan for the clocks changing on Sunday
    • Schedule for week 7
    • Acc whiteboard
    • Counting house whiteboard
  5. AOB
  6. Notes from this meeting:
    • Hovanes to try scan in x of beam position on AC today
    • Follow that with Jay's suggestion & harp scan. Checked w Todd & Mike M - ok.
    • Sasha to do test run w PS at lower field today
    • Mon & Tues downtime to be used for CCAL installation. Controlled access should be ok.
    • Discuss 7GeV run plans more on Monday
    • Tim will adjust target compressor cooling water valve on Monday - should be ok until then. Chris & Alexandre see all the alarms.

  1. Last 24h
  2. Issues
  3. Reports
  4. Plans
  5. AOB
    • Notes from today's meeting: Hovanes to scan AC early pm.
    • Shifters to call Sasha if beam goes off for >= 1h during weekend daytime, to check BCAL LED trigger diffs between up & down and long & short modes
    • Sasha said shift crew should not use the cosmic trigger at all. Use production trigger even if only to collect cosmics during a long down-time.
    • Tentative plan for V-wire TAC run on Wed next week at 2 PS settings, nominal & lower Eg. Then follow with low Eg test runs. Maybe a 3rd TAC run after the low E data-taking.
    • Q on whether to go ahead w second set of 7GeV test runs - need collaboration agreement
    • Remember to make a plan for the clocks changing on Sunday
