    Entry number 272094

    keyword=Summary of events from 10:00 to 11:30

    10;00 Increase Raster to 6 x 6
    10:15 DAQ Crashed again
    Do not know what is wrong with DAQ
    Decide to check to see if it is correlated with beam
    Request MCC to mask target
    Move target to empty position
    Request MCC to move beam y position from 2.9 to 2
    Decrease Raster size to 4 x 4

    DAQ is now working

    Mask target
    Move to 3He
    Take 2 ua beam Raster size 4 x 4 start DAQ Runs 2034 and 20944 DAQ ok
    Take 2 ua beam Raster size 6 x 6 start DAQ Runs 2035 and 20945 DAQ ok

    Request MCC to increase beam from 2 to 5.5 ua and reduce raster
    to 7 x 5

    RASTER Problem Caused by MCC
    Raster vertical accidentally increased dramatically causing
    HAND detector high voltage alarm went off
    Polarized target tempaerature and oven alarm went off.
    Call MCC stop beam
    Raster back to normal 7 x 5
    Target temperature coming back to normal

    Move to empty target position
    decrease beam to 2 ua
    start DAQ ok
    Raster ok
    Move to 3He target

    Check beam 2ua Raster and DAQ ok
    Increase beam to 5.5 ua DAQ still okay

    Back to production running.
