    keyword=beam current correlated with hall-C beam.

    Noticed that the hall-A beam current is correlated with the hall-C beam current.
    when the hall-C beam went off, we got more current.
    called MCC, and they explained that MCC shut hall-C beam off by turning off the
    hall-C laser, the hall-A laser and hall-A beam was not touched in the mean time.

    the attached plot shows the hall-C current, top curve, and hall-A current in the
    last few hours.
