[clas_members] [Rgc] [Revised Logentry] RC Daily Summary

[Sebastian Kuhn]

Just to add:

1) Thank you SO much Carlos for your heroic jumping in as temporary shift expert
2) To give Carlos some time to recover, please call ME (Sebastian) at (757) 639-6640 instead of the RC cell phone if you need to talk to the RC, until this evening.
3) Due to the ongoing CLAS collaboration meeting, we will delay our daily RC meeting once again to 3:00 p.m. (not 2 p.m.)

- Sebastian

RC Report 23 June 2022

General Summary

- In general the day has been with ups and downs with respect to the beam behaviour.
- We started to get Moller runs since early the day unsuscesfully due to issues with a quad magnet. After severl attempts it was decided to postpone the Moller run and focus in production on NH3.
- Small modifications to the target were made by Maxwell https://logbooks.jlab.org/entry/4005916.
- It was changed the raster configuration to Vpp=2.2 for both X/Y, Xoffset=0.1, Yoffset=-0.1. It is not clear that these changes achieve the desidered position of the raster beam. Before ---> https://logbooks.jlab.org/entry/4005948 After ---> https://logbooks.jlab.org/entry/4006131
- Maxime reported some issues with the raster monitos and has been in communication with Maurik and Sergey --> two rastermon sessions were running in the same machine. Killing one of the processes solved.
- Rafaella worked in the hodoscope callibration HV.
- The shift leader during Owl shift felt suddenly ill. Stuart called RC and safey guards, It was called an Ambulance which took him. The RC replaced the Shift leader.
