Current Status
- SHMS: 8 degrees, -9.2 GeV, 1x, 2x 1-7 off
- HMS: 20 degrees, -5.878 GeV (setting 9)
- Spectrometer magnets ramped down
- Controlled access during RF recovery
- 5pass beam, 30 to 60uA this afternoon
Run Plan
- Continue data taking.
- Hall A pass change next week ( Monday through Wednesday)
- Short RF recovery today
- before RF recovery:
- Take positron data until Monday for boiling/rates studies ( need stable beam up to 60uA)
Issues
- CODA crash was monitored overnight as suggested by Bob https://logbooks.jlab.org/entry/4069728
Notes
- watch beam stability
- need more shift workers (always)
To do
- Install Q1 SHMS vacuum gauge (~3hr)
- calibrate SHMS Dipole LN2 valve during next access (Amy Comer, Steven Lassiter; Heidi Fansler) https://logbooks.jlab.org/entry/4064490. For now, monitor the ice accumulation if any https://logbooks.jlab.org/entry/4064528
- reboot or replace the SHMS angle camera (Dave Gaskell?) https://logbooks.jlab.org/entry/4067528
- replace GEM gas bottle (Jixie)
- check UNSER control box (Dave Mack) https://logbooks.jlab.org/entry/4068738
- reboot NCG readback (Ellen Becker) https://logbooks.jlab.org/entry/4069438
