It seems that the ChIo is counting at a very low rate, around 100/s instead of 5000/s in previous runs.
Thomas R is called at 20h to fix the problem.
See scalers of Run 343 at 20h09.
Run stopped at 20:32, there is no bias on the cathode of the Chio, Thomas is entering the room.
HV on cathode put on again. CHIO should work better now...
