    keyword=Charge Asym Sign Test


    Charge Asymmetry Sign Test: a large Aq is induced by turning off the positive
    Pockels cell setpoint.

    Initial PC setpoints:
    .......setpoint...readback
    Pos=7.690........3.24
    Neg=7.752.......3.17

    Pos taken to zero, readback = 0.19
    IA feedback was disabled, and the IA setpoint was left at 4.93 V.

    Approx. 15 minutes of data was taken at each setpoint.
    Beam current was just over 12 uA

    HWP OUT (RWP 6435)
    Parity Run 1552.
    L-HRS run 20617.
    R-HRS run 1617. (DAQ trouble during this run may junk the data.)
    Injector Parity run 5187 (DAQ trouble ended this run).

    HWP IN (RWP 6650)
    Parity Run 1553.
    L-HRS run 20619. (20618 is a good run, taken before these runs, while fighting the R-HRS DAQ.)
    R-HRS run 1618.

    At end of test, HWP left IN, POS voltage setpoint returned to 7.690.
    IA feedback remains disabled for the following PZT tests.
