Instruction for RCs
- Half-wave plate change
- Follow the instructions in the link above whenever the HWP is changed flipped.
Past 24 hours
- Work in Hall yesterday all completed
- Well done and thanks to all involved!
- Beam back around 18:30.
- Swiftly followed by PSS issues that kept us down until the end of swing.
- By the time beam was back, NPS temperatures stable, skipped test for setting KinC_x60_4 in the run plan
- In switching back to KinC_x50_4' kinematic, ran into issues with the magnet GUI
- GUI was VERY slow and unresponsive, problems from earlier in the day then came back to haunt us
- HMS Q3 did not seem to display at all
- Contacted engineer on call, Ellen, who killed a process that improved things.
- The GUI then became, charitably, usable. We struggled through and got the kinematic set up though (with the added fun of a HMS dipole interlock)
- Luckily, no further kin changes in the near future, but we should look into this issue further.
- After that, very little drama. Beam was good overnight and data taking has been ok, with one exception.
- VME2 and VME3 seemed to die for runs 2524 and 2525. The shift crew only noticed this when they observed that the rates were lower than expected.
- Please check carefully for issues like this.
- Hopefully the crew can clarify how they resolved this if they're in the meeting
- Since then, smooth sailing.
Issues:
- Magnet GUI very slow/unresponsive
- VME2/3 not running/dying for some reason
- Please watch out for this!
RC Summary
https://logbooks.jlab.org/entry/4213959
Current Status
- Running production on KinC_x50_4'
Near Future Plan
In the near term future:
- Sometime in the future, we will invite Vlad to give an insight into the high radiation test results.
- We will perform a corrector coil beam steering test for the next angle setting with a non-zero corrector coil field.
- Is this still going ahead?
- Keep running the current setting
Special Studies
- Moeller run on Monday? (06/11/23)
- Try to fit in the KinC_x60_4 test?
- How high priority is this?
Standing Issues
- Implementing checks for charge asymmetry in alarm handler and online analysis: https://logbooks.jlab.org/entry/4213566
Planned Accesses to the Hall Today
- None
Planned Accelerator Configuration Changes
- Pass change is not next Tuesday, it's on the 13th of November (13/11/23). So we have ~10 days of 5 pass beam left.
Special Requests
- Peter took a look at the resolution degradation over time, a topic it might be worth discussing further.
