    total charge for thetacm = 135 degrees is 8.65 Coulomb

    switching kinematics to thetacm = 155 degrees

    3634 20:02 0.14M sieve slit in electron arm
    3635 20:11 0.37M sieve slit in electron arm

    Hadron Q2 quenched. Access needed to reset power supply.

    3636 21:09 0.31M sieve slit in electron arm

    many trips - gone to pulsed beam

    3637 21:31 1.2 M sieve slit in electron arm
    3638 21:41 1.2 M sieve slit in electron arm
    3639 21:50 1.2 M sieve slit in electron arm
    3640 22:02 0.32M sieve slit in electron arm

    22:15 Hadron arm finally set. arm at 34.073 degrees, mom. is 0.7418
    Sieve slit now out of electron arm. Will take pointing data.
