    keyword=Day shift summary

    08:00 Start of shift. Q1 is down on R-HRS. Previous shift has been unable to reset and has notified RC. We continue taking data on L-HRS.
    ~9:00 called RC and Tech on call about R-Q1 problem. May need to cycle power supply in hall.
    09:40 RC here. Called MCC to request escorted controlled access for Ed Folts to tryo to reset power supply.
    09:53 Ed makes access. No luck restoring R-Q1. Cryo problem. (Lead outlet pressure too high??)
    10:17 Request that MCC restore beam
    10:29 Beam back
    11:45 RC advises R-Q1 will be down until tomorrow morning.
    13:20 Ask MCC to close slits for Compton test. Moving target out of beam.
    ~13:30 Asked MCC to tune for Moller (with slits closed for Compton tests)
    ~13:30 R-Dipole crashed. Indicating Lead A voltage fault. R-Q3 crashed a few minutes later.
    Will leave both magnets off since R-Q1 is already off preventing us from running.
    14:40 LHe level in R-dipole is beginning to recover from quench
    14:50 LHe level in all magnets is good (~80%).
    16:00 At end of shift, Compton studies are continuing with low current beam with small slit settings on chopper. Efforts at parallel Moller studies have been abandoned.
