    keyword=Moller target masking incident

    When the Moller target was removed the MCC left the beam on and masked
    the target motion. This was a wrong thing to do. The Moller target can
    be rotated with the beam on and no masking is needed. However,
    the vertical target motion is connected to FSD since thick structure
    elements would be moved through the beam and the beam has to be OFF
    when the motion is masked! We noticed too late what was happening
    and the target was moved through the beam. The current was 0.3µA
    and no trip due to radiation occured. The induced radiation of the Moller
    target should be measured during the next radiation check.
