 Fri Nov 10 10:46:54 2017, SL, Investigation of E detector thickness
|
While changing HI degrader foil to 10um Al, the E detector was investigated, due to previously observed alpha punch-through.
On visual inspection, the E detector appeared to be 1mm in thickness, leading us to believe that instead we were not fully depleting the detector.
The bias supply was investigated, and was found to be supplying a lower voltage (on all channels) than was shown on the display (14V -> 2V |

Fri Nov 10 08:31:06 2017, TD, CAEN V767 TDC trigger/channel 0 logic change
|
Approximately 5-10% of events overnight were 'bad' i.e. missing TDC data
Checked the CAEN V767 trigger/channel 0 logic (without beam) this morning
