    keyword=Procedure: to change Beam Halfwave Plate


    When changing the beam halfwave plate (HWP), we request that you also
    instruct MCC to change the Rotating wave plate (RWP) and Pockels cell
    high voltages (POS and NEG) as well.

    HWP.....RWP......POS.....NEG
    ...IN.......6250.....7.704.....7.538
    ..OUT...6200......7.673.....7.569

    These changes are negligible for spin duality, but they are important for the
    continuing HAPPEX efforts.
