Friday June 24

  1. Last 24h:
    • Accelerator went down at 6:20 as planned.
    • RF recovery coupled with trying to get more beam to Hall C did not go well. We were promised beam after 5pm, then 7, then 1030.
  2. Shift Summaries
  3. Reports
  4. Issues
  5. Plans
    • Sasha - check straight target configuration
    • Sasha - make new CPP configuration as requested by email
    • Richard (if not done during owl) - repeat 2 rows in microscope scan
    • Return to production. Cycle through 240M events for each of 45perp, 45perp, 135para, 135para, then 60M events on the AMO on the goniometer.
    • Production as above should be our default for 6d, with 1d on empty target.
    • Try again for the TAC run on Friday
  6. Commissioning steps temporarily postponed:
    • Flux optimization/Act .Col. calibration
    • Bleed-through test: measure bleed-through with A slit as usual and A slit completely closed to see whether using B slit would help.


Thursday June 23

  1. Last 24h:
  2. Shift Summaries
  3. Reports
    • From MCC: Reminder that 911 from lab phone is forwarded to normal 911 and also automatically informs the crew chief, guard shack, etc that there's an emergency, crew are CPR qualified & have AED. This doesn't happen from RC phones (or cellphones). No problem w 911 from other phone; if there's a lab phone handy it saves some time.
    • Power shed 3-4pm today, beam restoration likely 5pm+.
    • MCC planning to raise the current to Hall C.
  4. Issues
  5. Plans
    • No beam until swing.
    • Walk-through at 11am
    • Site exit opposite Tech Center closed most of the day - need to exit by resfac or Lidl.
    • Put the target back (done).
    • Sasha - check straight target configuration.
    • Sasha - make new CPP configuration as requested by email
    • Richard - repeat 2 rows in microscope scan
    • Return to production. Cycle through 240M events for each of 45perp, 45perp, 135para, 135para, then 60M events on the AMO on the goniometer.
    • Production as above should be our default for 6d, with 1d on empty target.
    • Try again for the TAC run on Friday evening
  6. Commissioning steps temporarily postponed:
    • Flux optimization/Act .Col. calibration
    • Bleed-through test: measure bleed-through with A slit as usual and A slit completely closed to see whether using B slit would help.
