    keyword=[Target] Rate momentarily returned to 5 kHz, probably due to beam crash

    The rate reached 5 kHz for a few minutes. We tried closing the run valve but this had little effect. In retrospect the problem was most likely related to the beam position rather than helium levels. Rate is back to 700 Hz again.
