    9:28: bigBite HV trip (in the same time the machine tripped). Stop run 5612
    9:38: started run 5613. We could have restarted early but the General Accelerator Parameter Guy is displaying (wrongly) that we don't have beam. I called MCC for an update and they told us we have beam. We wasted about 5 min because of this.
