keyword=BB chamber HV alarm
around 23:30 BB wire chamber HV tripped without any alarm. Later Yi find
the problem from online replay. Then we found the error shown in the gui.
Before it had an alarm to notice shift worker. Now we don't why the alarm
doesn't work. I'm sure the audio was on.
So please look at the HV gui periodly and ask the shift work keep eye on
