    keyword=04/03/10 Day Shift Summary

    07:30 AM have beam back
    08:00 AM Run Plan for Lead integrating mode is still going on...
    We just get the fast feedback going for a minimal current =
    2.5 uA
    08:20 AM Luis is coming in, and he works on A_T scanning...
    move A_T detector around, to see where the optimal position
    is
    09:00 AM Q1 L-arm magnet quench
    09:15 AM Mark and Sasha get access to the hall; Mark checks spectrometer magnets, and Sasha refills Moller magnet
    09:30 AM Mark requests for a tech on-call (Howard Smith)
    09:40 AM I page the tech 0n-call
    09:45 AM Mark finds two L-arm magnets quench; two R-arm magnets quench
    10:08 AM move the target to the empty position
    10:32 AM wait for MCC to turn Moller Dipole/Quadropole on
    10:55 AM Tech (Howard Smith) is coming to fix the quadropoles...
    11:05 AM Escourted Access; page tech (Howard Smith)
    11:30 AM Mark and tech (Howard Smith) come out of the hall
    11:40 AM MCC plans to send the beam back
    11:55 AM Sasha asks MCC to move Moller target (#1)
    12:15 PM Moller Commissioning starts...
    12:24 PM Moller is still being tuning; no Moller electron peaking in
    the energy spectrum, but the output result looks much better
    after switching the cable (supposed to be)
    12:45 PM get good Moller asymmetry result from old DAQ; Moller run
    good number is from 14238
    01:00 PM adjust HV to change PMT signal pulsar's height in Moller
    FADC
    01:26 PM Sasha calls MCC to change the beam position in order to get
    a more stable beam currrent
