Back to:
4:00PM Run Meeting, Counting house meeting room (200C)
RC: Carlos Ayerbe
Summary of past 72h:
Accelerator
- 7:30 - ARC magnet issues causes the beam to be off. Same problem was reported last Wednesday. ---> https://cebaf.jlab.org/dtm/open-events?event_id=3456
Friday March 2nd
Swing shift
- data production
Saturday March 3rd
Owl shift
- data production
- 00:50 beam off ~1.5h due HPA water problem
- Due to a misunderstanding in the crew, two runs with H2 were taken instead of He3.
Day shift
- data production
- 09:27 Beam to the Hall off ~1.5h due to Beamstopper A-chain dropped ---> https://logbooks.jlab.org/entry/3541990
Swing shift
- data production
- 19:50 Raster X power off ---> https://logbooks.jlab.org/entry/3542196
- 20:40 Bill Gunning enter under control access to repair. 24V power supply replaced ---> https://logbooks.jlab.org/entry/3542226
- ~2h without production.
Sunday March 4th
This day we dedicated to take H3 and He3 data in exclusive until obtain ~30k good electrons at each target.
Owl shift
- data production
Day shift
- data production
Swing shift
- data production
- Beam quality degrading along the shift.
- 21:40 1L24 SEL Quenches and 2L09 dropped HV. Beam off for 3h.
Monday March 5th
Owl shift
- 9:00 Beam Studies
- Parasitic data
- 11:00 Controlled Access
- LHRS Polarity changed
- Vacuum minor inspection
- Walk-through
Day shift
- LHRS positrons data
- RHRS data production
DATA Status
Round IX. Column 25/(24+4).
Plan:
- -Changing LHRS polarity
- -measuring positrons (LHRS)
- -Normal running RHRS
Total: two shifts.
