    keyword=Pockels Cell Voltage



    We are seeing a stable 680. ppm asymmetry in beam current in Hall A.
    I have corrected the high voltage settings on the Pockels cell to zero it.
    Given that the correction is ~-75 ppm / HV unit that's a 9 units correction:

    Old value New value
    Left 639 ->648
    Rigth 623 ->614

    After that change, the asymmetry has been measured to be A=-37+/-24 ppm.
