    keyword=BB HV and ROC5 problems

    After around 100k events of run 2165, BB HV tripped. While fixing the problem, the run would not end cleanly due to a problem with ROC5.

    The problem was probably the result of beam instability: the Compton rate in the chicane jumped around the time of the trip.

    HV is now restored. We will attempt to restart with run 2166.
