Monday January 23

Past 72 hours

  • Beam was off from Friday 7:30am to Saturday 2am due to vacuum issue in south linac. Friday ABU: 4.0h
  • Saturday: Ran on amorphous (goni), 300 nA. Until Sunday 9am when Hovanes started diamond alignment. Saturday ABU: 18.6h
  • Sunday 9am-5:30pm: diamond alignment. Sunday 8:30pm - Monday 7:30am: First production 0/90/45/135/amo cycle (see CBrem peak). Then did Harp scans. Sunday ABU: 14.3h

Shift Reports

Reports

Issues

Plans

  • Production on amorphous (Goni, 300 nA) until the diamond is aligned.
  • Diamond alignment: Sunday morning, ~9am. (Hovanes)
  • Then production on diamond radiator, 4 orientations + amo. 300 nA. Presently, we do each orientation once (not twice) and each run is nominally 2h, including the amo run.
  • Tomorrow (Tuesday, 24th: 4h of beam studies + 2h beam restoration):
    •  ?Safety Walkthrough (M. Dalton + trainee(s))?
    • Scot to access to take out Vlad's chiller
    •  ?Investigate the faulty pressure sensor?
    •  ?Chris Carlin to fix the target controls?

Past 24 hours

Shift Reports

Reports

Issues

Plans

  • Thursday evening and Friday night:
    • Once beam come back, do Harp scans.
    • FCup test of our beam dump BCM.
    • Run 1h on the amo radiator of the goni (baseline for next runs below). 250 nA
    • Run 2h on 0.19E-4 RL amo radiator on radiator ladder (250 nA).
    • Run 2h on 1.12E-4 RL amo radiator on radiator ladder (250 nA).
    • Run (until the beam is taken away in the morning) on 3.4E-4 RL amo radiator on radiator ladder (250 nA).
  • Beam off starting Friday morning around 7:30am to fix vacuum issue in south linac, until 4pm(?).
  • When the beam comes back:
    • Harp scans
    • Production on goni amo radiator at 300 nA until Sunday morning.
  • Hall access:
    • Sergey F.
  • Diamond alignment: Sunday morning, ~9am.
  • Until then production on amorphous.
  • Link to runplan

Thursday January 19

Past 24 hours

  • Ran on empty target until 7:20am. Then, beam was taken away for beam and RF study and acceptable beam came back only Thursday at 1:10am. ABU= 4h for the day
  • refilled the target around 4:15pm.
  • Several accesses done during the day:
    • Scot
    • Sergey
    • David Lawrence
    • Cody
  • Took amorphous data, starting around 1:10am after aborted attempt to check diamond alignment.

Plans

  • Beam off starting around 10am for RF study, nominally until 4pm+/-4h.
  • Hall in controlled access?
  • Diamond alignment: Friday day ? (Hovanes unavailable today)
  • Until Friday day, production on amorphous?
