[Halla_running] Status update

[Sanghwa Park]

Hello all,

We had overall smooth running throughout swing and owl with some
interruptions due to problems with cryomodules. Around the end of owl
shift, beam was down for an hour because of 1L17 comm error. It was
restored around 7 am and we restarted data taking. Thanks to our owl shift
crew Junhao and Nathaniel for the extra hour of shift. :-)

>From around 8:30 in the morning, there was no beam for 4 hours due to 1L17
tuner issue (related entries can be found from:
https://logbooks.jlab.org/entry/3620823). Repairs and machine restoration
completed around 12:30. Since then, we are back to production mode.

Plan for today is to continue data taking with Tritium target. No
target/kinematics changes.

Tomorrow, the beam will be taken away at 8:30 for the scheduled beam study.
The first 1 hour will be for the injector study (no beam to the hall).
After that, MCC needs Hall A to do 1C12 calibration. While we will keep the
hall locked up throughout the beam studies, we plan take BPM pedestal runs,
raster calibration and dummy data.

No access tomorrow. Any work to be done in the hall should plan for
Tuesday. Let RC know if anyone need an access on Tuesday.

Enjoy the rest of the weekend,
Sanghwa (Hall A RC)
