    Shift Summary

    16:00 Continue g2p production with momentum = 0.6200 GeV.
    16:40 Changed HRS momenta to 0.5828 GeV.
    17:00 Beam is off due to MCC RF problem.
    18:10 MCC fixed the RF problem, tuning beam back to the hall.
    18:55 Back to production.
    23:20 Adjusted target offset to +70000 to prevent beam scrapping on the C12_40 target.
    23:30 Changed HRS momenta to 0.5478 GeV.
    24:00 Shift ends with production at 0.5478 GeV.
