    New Crew on shift : Yi Zhang, Eric Voutier
    -----------------

    12:00 Waiting for beam

    12:37 MCC is ready to send low energy duty cycle beam in the hall,
    Paging JP ... plans are fixed for Harp scan, Raster check and
    spectrometer commissionning with optics and carbon targets

    12:50 MCC is sending 2uA CW to check things

    01:23 MCC goes up to 8 uA to do CW checking of the beam line

    02:40 beam is going through the Compton chicane, going for raster
    check; moving to carbon target

    Run # 20112 check with empty target
    Run # 20113 carbon in place... spot++ is not working

    03:15 Analyzing run 20113 for detector check
    Notice some possible timing problems on the scintillators and
    some gain matching to adjust in every detector components

    04:00 Many issues on the accelerator side : fast feedback, 1H03B BPM,
    too large beam spot

    04:20 Beam spot was adjusted and is within spec at 1H03B
    (elog 1395490)
    MCC is proceeding to further tuning

    Run # 20114 Detector check-out with optics target

    05:30 Calling for controlled access to set HV on NaI detector & S1

    06:15 Alexandre is in, checking detectors and DAQ
