    keyword=Day Shift Summary

    08:00-09:30 Survey and raster repairs in progress.
    09:30 Raster repairs finished.
    10:00 Survey finished.
    10:25 Hall inspection finished and ready for beam.
    10:25-11:25 Tuning raster size, doing harp scan, investigating beam spot size.
    Runs 1752-1760 are raster checks. Beam spot area is too small by about a factor
    of 3, but we decide to run with it since fixing it would take 1+ hours, and we're late
    already.
    11:25 Carbon pointing run 1761. 70uA, no raster.
    11:35 End pointing run. Moving to LH2 target for production running.
    11:48 Start production running, run 1762, 70uA, raster on.
    11:55 Asking for 50uA instead of 70 to reduce deadtime.
    11:57 Asking for 35uA as 50uA still gives too much deadtime.
    12:01 Asking for 50uA after realizing that T1 prescaling can be much increased.
    12:05 Major DAQ problems. ROC14 stopped responding, afterwards very difficult
    recovery. Runcontrol would not record ANY events and not open ANY run
    files, not even empty ones. Finally rebooting adaql2 cured the problem. Meanwhile,
    the VDC HVs on the right arm tripped because the control crate was mistakenly
    rebooted too during DAQ recovery attempts.
    12:50 Back up running. Start run 1771, first good production run at these kinematics.
    13:27 Asking for 60uA before run 1773. T2/T4 prescales adjusted.
    15:27 End run 1778. Moving to 4cm dummy target.
    15:40 Start run 1779 with 4cm dummy target. 30uA. Rates actually slightly higher
    than with production target.
    16:00 Run 1780 on 4cm dummy in progress at end of shift.
