    November 17, 2007 Owl Shift Summary

    Owl Shift Crew:
    V. Sulkosky (SL), Y. Oh (TO)

    Summary
    =======

    00:00 Start shift in Controlled Access to fix fastbus crate
    power supply for the VDCs.
    01:50 Power supply replaced, Alexandre and Bob are swapping out
    the TDC module that was replaced during Swing shift in ROC3 slot 4.
    02:25 Alexandre and Bob are out of the Hall. Hall A is in Beam Permit.
    02:35 Beam back checking beam position and raster.
    02:45 Noticed that left Q2 tripped off at 2:38 due to an overtemp
    fault. Called RC and paged tech-on-call, since fault will not clear.
    03:20 After consulting with Heidi, I requested a controlled access to
    reset the left Q2 power supply to clear the fault.
    05:05 MCC called, they have an RF problem in the injector. Beam will
    be off for a while.
    06:30 Right Q1 has been recovered and the dipole liquid helium level
    is almost normal.
    06:55 Asked for Beam Permit.
    07:00 Began ramping right dipole to set momentum.
    07:33 Mask target to move to Carbon beam Left.
    07:49 Move to Iron beam left target.

    Left HRS
    ========
    momentum at 3.396 GeV/c, theta=15deg
    07:26 Run 2555, 328k, 10uA on 10 cm Dummy
    07:40 Run 2556, 380k, 10uA on Beam Left Carbon
    07:54 Run 2557, 488k, 10uA on Beam Left Iron
