Monday August 8

Past 72 hours

  • Running on empty target until Friday morning, 7:15am.
  • No beam until Saturday 1am due to RF-recovery (Friday 7:15-11am) and then several accelerator problems (RF-recovery recovery, storm). Then, very good beam (in terms of ABU, trip rate and stability)
  • From Saturday 1am, production on Pb target (30nA)
  • 40.1h of ABU (59% efficiency).

Shift Reports

Reports

Issues

Plans

  • Today's 5 -> 4 pass change for Hall C is postponed to tomorrow. Consequently, 4 -> 3 pass change next Monday will likely be postponed to Tuesday too (So Monday 15th becomes a good day for a TAC run).
    • Malte will change a couple of PMT basis in FCal.
  • Production on Pb target.
    • We are now doing para/para/perp/perp/amo
    • Run event goals are 50% higher (360M for diamond, 90M for amo)
  • Thursday 11th will probably be a maintenance day.

Friday August 5

Past 24 hours

  • Running on empty target (60 nA).
  • Plan to do TAC run Thursday was postponed (Today, or around Aug. 15th).
  • Everything is going well: 15.1h of ABU (63% efficiency). Time loss mostly due to thunderstorm (3h).

Shift Reports

Reports

Issues

Plans

  • RF recovery until ~noon +/- 1h. Hall C planned to be down until 1pm.
  • Access to put back Pb target if no TAC run today?
  • TAC run in the afternoon ? (Thunderstorms forecast), or production on Pb.
  • No RC meetings this week-end (unless some problem occurs).
  • Monday day: 5 -> 4 pass change for Hall C (Around 4h. Mostly invasive).

Thursday August 4
