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
Change of plans!!!
All the time schedule is moved one hour late in order to allow Hall C finish a kinematic point before change polarity with control access.
Hall A and B entered in controlled access early (9:00) so we didn't run parasitic runs.
- 9:00 Beam Studies (+1h)
- Parasitic data (No Hall A)
- 11:00 Controlled Access ((RadCon requested at 9:00)
- 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.
EXTRA:
- Tuesday RF Recovery
- Start 8:30
- Ends 12:30
