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.
