RC Summary
Current Status
Near Future Plan
- We will perform a corrector coil beam steering test for the next angle setting with a non-zero corrector coil field.
- Wednesday, November 2, during the beam study, 7:00 beam stops, 7:30 a.m.: sweep the hall open for maintenance; Hall will enter restricted access at 8:00-8:15 a.m., and sweep close when the NPS maintenance work is completed (no time limit).
We will attempt the following maintenance items:
- Put the SHMS to the largest angle possible. Full hall sweep.
- NPS students will remove all PMTs + bases. Hall tech support is needed for this part.
- Two new bases with the low voltage regulator bypassed (verified) with be swapped into the NPS.
- NPS shielding installation: large sheets of borated-polyethylene
- Heidi is looking into adding an additional bandit to ensure SHMS dipole stability.
- Chandan and Dave Mac will access and check the HMS hodoscope patch panel. to address this issue: https://logbooks.jlab.org/entry/4210267
- Aaron will push new code for the NPS chiller controller.
- Joe will guide a walk-through at 1 p.m.
- Sometime in the future, we will invite Vald to give an insight into the high radiation test results.
I am sure the maintenance list will grow as we get closer to Wednesday.
