    keyword=Swing Shift Run Summary

    16:21 Run #3766 ended. Tim Ngo is performing NMR measurement
    16:25 Started Run #3767. Polarization from NMR measurement is 50.8%
    17:26 Started Production Run #3768. Heater temperature to He3 target was raised by 10 degrees by Aidan Keheller
    18:10 New polarimeter constant was changed to c= 0.426%/mV for NMR measurements
    18:27 Started Production Run #3769.Replay ok
    19:25 Started Production Run #3770. Replay ok
    20:26 Production Run #3770 ended. Hall B changed Half-wave plate to IN
    20:28 Started Production Run #3771. Replay ok
    21:00 Noticed Charge Asymmetry Problem on the Happex Feedback Monitor (asymmetry was observed at -2374 ppm) Ran Qasy an noticed an extra peak.
    21:15 Feedback was on standby. Called MCC to turn FB on Also the MCC was asked to decrease BPMA y from 1.626 to 1.4
    21:31 Started Production Run #3772. Replay ok. Called MCC to change beam position parameters to accepted values (BMPA x=0.428 y=1.446 BMPB x =-0.078,y =-0.042)
    22:11 Stopped Run#3772 run early to reboot genslo1 (problems with reading shower and preshower thresholds)
    22:19 Tim Ngo took NMR run (polarization 51.4%)
    22:21 Started Production run #3773. Replay ok
    23:04 Noticed BMPA and BMPB were not in the right range on production run 3773. MCC said the problem was caused by a mismatched magnet.
    23:24 Started Production Run #3774. Replay ok
    23:59 Noticed Happex analyzer stopped running during production run 3774. The RC (Tim) rebooted the Happex DAQ
