    Swing Shift Summary

    16:00 - On Kin point 38, finishing up Rate Check with LD2 and radiator out.
    16:41 - VESDA alarm: In zone, Urgent, Air Flow. In Beamway. Called MCC.
    They saw the problem too and came over and reset it.
    16:50 - Asked for 11uA. Put radiator in 5%. Started last part of rate check
    17:25 - MCC took beam for 15min to do tests.
    17:40 - Beam is back...Started Gamma-D production runs
    LD2, 5% radiator, 11uA.
    18:32 - Q1 died. Tried to set to 0amps, turn off, reset, turn on. Did nothing.
    Pressed the green button #9 in the middle room, and tried resetting
    again. Now it works. Took ~10min to fix, all together.
    19:48 - Q1 died again. Reset and used green button. Fixed in 8min.
    20:47 - Q1 had yet another Earth Leakage Failure. Green button 4 times.
    Fixed in 10min.
    MCC called saying we are authorized to run with one ion chamber masked
    because the left and right chambers are redundant.

    22:50 -
    Many Magnet Problems:

    LQ1: Same problems as before. Earth Leakage Failure, Max Current Set, Spare Interlock, and it stopped reading back. Fixed it using green button pushing method, and on gui. Took a few tries for it to work.

    LQ2: This one is fine.

    LD1: This does have power supply on, and it looks fine in the LD1 System GUI (reads back a constant 50.1) but on the Tools GUI there is no readback, Had a Lead A Flow fault and a Dump Mode Fast that was red, but these dissapeared when the reset button in the GUI was pressed.

    LQ2: This one is fine.

    LD1: This does have power supply on, and it looks fine in the LD1 System GUI (reads back a constant 50.1) but on the Tools GUI there is no readback, Had a Lead A Flow fault and a Dump Mode Fast that was red, but these dissapeared when the reset button in the GUI was pressed.

    LQ3: There was an Interlock fault which went away when reset was pressed, but the Quench fault remained. It won't go away just resetting in the GUI.

    RQ1 is fine.

    RQ2: There was an Interlock fault which went away when reset was pressed, but the Quench fault remained. It won't go away just resetting in the GUI.

    RD1: There were faults in the Lead A Flow and Lead B Flow but they went away when reset was pressed in the GUI. There is a Power Supply fault that goes away when you press the "on" button, but then it turns itself off and the fault returns (about 2 seconds later). It is Off and Disengaged.

    RQ3: There was an Interlock fault which went away when reset was pressed, but the Quench fault remained. It won't go away just resetting in the GUI.

    ALSO: The N2 level CLL71Q210 is around 23 or 24, which is under the required 25. The rest of these and the H2 levels look fine.

    Went down to the hall with Rob Feuerbach. Reset magnets and rebooted IOCs. Eventually things looked better.

    1:00 - On the Left HRS, all magnets are now responding as they should. Didn't touch the RHRS magnets...they're not as important right now.
