** Evening temperatures impacted cooling in building #38 (South Linac - east end). Supplementary cooling was added and stabilized the situation, but facilities may need to help with additional cooling. The are indicators of challenges of running through the summer.
+
−
** Thunderstorms affect operation; root causes are not known. Possible causes (Jay): 1. u-phonics induced by the thunderstorms, C-100 cryomodules not adequately damped for 10-80 Hz vibrations, coupled to waveguides to upstairs. 2. Imperfect grounding. 3. micros electrical discharges affecting low level RF. 4. Long helix master RF cable running to south linac in water-filled trough.

Spreadsheet with list of runs

Wednesday July 27

Past 24 hours

  • The accelerator went offline at 5:30 PM Tuesday due to a power glitch to CEBAF. The Tagger and PS magnets tripped off. Waiting for issues with a RF zone and a bulk power supply to be resolved
  • Data taking on Pb target, approx 1.0 B triggers in the past 24 hours

Shift Reports

Reports

Plans

  • When beam returns take harp scans, then resume data taking on Pb full target
  • Thursday day shift is scheduled for beam studies, beam in the accelerator but not to the halls. This would be a good time to work on the CTOF PMT#3

Tuesday July 26

Past 24 hours

  • Switched to Pb target around 10:30 AM Monday
  • Data taking on Pb target, approx 2.8 B triggers in the past 24 hours

Shift Reports

Reports

Plans

  • Continue taking data on full target
  • Next opportunity to repair CTOF PMT #3 is probably Thursday, tentative RF recovery day

Monday July 25

Past 24 hours

  • Data taking on empty target, approx 2.7 B triggers in the past 24 hours

Shift Reports

Reports

Plans

  • Switch to full target running after the RC meeting
