Friday January 20
Past 24 hours
- Ran on amorphous radiator (250 nA) until 10am. Then, beam was taken away for RF work (high current push for Halls A and C) and [repairs]. Beam came back around 5:30pm. We did harp scans and ran on various amorphous radiators during the night. ABU= **h for the day
- Several accesses done during the day:
- Sasha (FADC replacement for TOF)
- Sergey
Shift Reports
- Day shift summary
- Swing shift summary
- [ Owl shift summary]
- [ Early Riser shift summary]
Reports
- [ Harp scans]
- TOF calibration (Beni), FADC replacement for TOF (A. Somov)
Issues
- Beam energy oscillation investigation (M. Tiefenback)
- 30% increase in transmission compared to Summer 2020 run.
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(?).
- Hall access:
- Sergey F.
- Diamond alignment: ?
- Until then production on amorphous.

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:
- Scott
- Sergey
- David Lawrence
- Cody
- Took amorphous data, starting around 1:10am after aborted attempt to check diamond alignment.
Shift Reports
Reports
- Harp scans (just our harp)
- Hovanes attempted to start diamond alignment between 10:50pm-1am. Not able to start due to lack of good beam.
Issues
- TOF rate issues (Beni)
- beam energy oscillation
- 30% increase in transmission compared to Summer 2020 run.
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?
