    Keyword: CCD camera of Hall A target OTR is replaced

    Description:

    1) I replaced the hall A target OTR CCD camera because of the many damaged pixel
    s. The shielding has been slightly improved an the camera should hold longer.
    2) I also rotated 180 degree the camera in order to have the X and Y axis orient
    ed properly.
    3) I set the camera gain potentiometer to its minimum (instead of maximum) in or
    der to reduce the effect of the pixel damage on the MaxVideo measurement abiliti
    es. The effect in MCC is that the sensitivity will be reduced. The sensitivity t
    hreshold may rise to 1 microampere or more.
