[Halla_running] [New Logentry] RC Summary 09/23/2023

We have good production running on polarized He3 cell @35uA beam current until late swing shift yesterday. We collected corrected equivalent charge of ~0.20C during the swing shift. After around 10 pm yesterday, we don't have any production data.

There is ongoing issue with accelerator which is stopping MCC to send beam to the halls https://logbooks.jlab.org/entry/4185800 and https://ace.jlab.org/dtm/open-events?event_id=18122. In the morning meeting with PD, Jay informed that Jerry and MCC are working to fix the issue (but no estimation). Jay mentioned that there aren't enough spare power supplied to replace, so need to fix the issue.

BBCAL group was informed about this downtime in this morning, and they finished taking cosmic data to study some low occupancy channels.

Target polarization with NMR at 8.58 am this morning: 41.5%

I would like to thank Vimukthi for signing up today's swing shift. We still need Shift leader for Tuesday (both owl and day shift), so I request you to sign up for those shifts.

Note: We won't have RC meeting today.
