    4:00 beam is @ 100 uA. we are in production.
    5:10 beam down. MCC called to say that they are calling in experts.
    some RF problems. could be a quick fix, could be a while,
    6:00 beam back up. 100 uA.
    6:30 go to 5 uA for dithering tests.
    6:47 go to 10 uA for dithering studies.
    7:05 go to 50 uA for dithering studies.
    7:17 on Moller setup. start of Moller measurements.
    10:10 Moller measurements done.
    10:20 Beam back on.
    10:41 MCC having trouble turning energy FFB on, so they would had to send us some tune beam.
    11:24 finally beam is back up. getting about 95/96 uA beam, but no energy FFB lock. Beam trips every time MCC tries to turn the FFB on!
    11:30 tune beam
    11:38 beam back up to 100 uA. FFB issue not resolved yet.
    12:00 lots of trips, cant get up to 100 uA.
