[Halla_running] [New Logentry] RC Report 2-5-23

Hi All,

Yesterday during Day and Swing we had smooth production data running at 45uA on polhe3 target. Beam was less stable during the night as ops had issues sustaining current to Hall C, so we had beam down several times and did not collect as much data as we would have liked.

Currently we are now back running production with 45uA on polhe3 target.

We are sitting at 23.8C of uncorrected charge for this kinematic  (26.1C of corrected charge). At this moment in time, as we start to take data again, the target polarisation is 54.4%. The polarisation has been looking really great these past few days throughout mostly consistent production running!

For shifters running the DAQ, please note that during swing shift yesterday we changed ps1 to 2 (previous setting was -1).

With many thanks indeed to Mark, it looks like our swing shift is now covered today.

The expected RF recovery will go ahead on Tuesday. I am aware of two outstanding access requests (listed below in special requests), but if there is anything else let me know.

Again, let's skip the meeting today, but please contact me as needed via phone/email.

Thanks - as always - to everyone for your continued efforts in helping us run smoothly.


Run Plan:
Continue running on polhe3 with NMRs every 4hours.

Special requests:
If the chance for opportunistic escorted accesses arise, the following requests are in place. But we still prioritise polhe3 running.
	- SBS GEM cable fix
	- Target oven heater check.

Shift schedule:
We are in very good shape until Feb 16th, except Fri 10th Feb Swing, which needs an SL and TO. There are plenty of chances to sign up after Feb 16th!

Meeting:
We are skipping the meeting today. But I am available 24/7 on the RC phone or email. Please get in touch with me about anything you need.
