Friday, September 30
Past 24 hours
- Long maintenance day dedicated to RF recovery and injector setup in preparation for Hall A coming online
- Tagger NMR Probe Meter (Scot)
- Calorimeter modules replace in PS (Sasha)
- We collected 43.6M raw-mode cosmics events since yesterday morning.
- Beam was restored to Hall D at 11PM last night. We completed the accelerator harp scans on 5C11/B and our radiator wire scan.
- While we were setting up for production after the harp scans, there was an issue with RF dropping out of HV. Beam has been down since then.
- Alex A. added back the standard physics monitoring histograms to the rootspy GUI [1]
- Shift summaries
Issues
Plan
- Once beam is back, re-do harp scans.
- Continue taking production data on LHe at 200nA today and over the weekend.
- PS Triggers collected since He target cell inserted:
- With target filled: 5.58B
- With target empty: 1.63B
- Empty/Full = 0.29, Percentage of flux spent on empty: 22.6%
Thursday, September 29
Past 24 hours
- Helium target was filled around 1:15PM yesterday.
- 2.5B triggers collected on helium target so far.
- Last run group: Empty Target PS triggers accounted for 33% of Empty+Full data set.
- Currently taking cosmics.
- Shift summaries
Issues
- 1.5hr downtime overnight from CPS breaker trip.
- FCAL Base lockup reset
Plan
- Maintenance Day
- Hall in controlled access.
- Walkthrough training at 10AM.
- When beam is back, we will continue taking production data on LHe at 200nA.
