    June 2 Shift Summary

    Right Dipole is down so normal Pentaquark running is not possible. Default running condition is now through the Compton. Energy and position feedback are off for the beam.

    0:00 HAPPEX running tests beam studies.

    0:45 Right Q2 tripped due to liquid level.

    1:30 HAPPEX tests over, switching left HRS to 0.55 GeV and 28.0 A on the left septum.

    1:47 Start changing target parameters.

    1:50 Finished cycling Q2 and Q3 on the left HRS.

    1:55 Moving to 4cm H2 target.

    2:00 Finished switching the left HRS settings.

    2:04 Finished changing the target to 4cm H2 target

    2:07 Request 3 uA of beam. (T3 = 3khz, vdcs<4uA)
    2;15 Request 10 uA of beam. (Deadtime = 60%)
    2:25 Request 3 uA of beam.

    2:30 Start 2 hours of ABU with 3uA and only left HRS on 4cm H2.

    Run 1617 2:28-2:52 1M
    Run 1618 2:55-3:17 1M

    3:20 Switching to 10 cm C optics target.

    Run 1620 3:28-4:02 0.77M

    3:47 Changed the onlana cuts file for one arm running

    4:02 Asked to go to 6 uA

    Run 1621 4:03-4:35 0.78M

    4:37 Changing to the 15cm H target
    4:37 Changing the left HRS momentum to 3Gev.

    4:46 Cycled Q2 and Q3

    5:45 Finished ramping up left HRS and Septum magnets
    5:45 Asked for 3 uA of beam.

    5:58 MCC is having problems getting the beam through the Compton with enough angle to correct for the septum stearing

    6:05 MCC called they lost four zones in the South LINAC.

    7:20 Talked with MCC and requested an access.

    8:00 Shift over waiting for Techs
