This GUI is used to enable/set particular voltage channels remotely.
- Start jmenu on the compton
- Type hv in the search bar
- Select card 3 - the first channel in this card is the photon detector. Nominal voltage 1750 V.
- For the scintillators on the laser table, select card 1.
The information below is for historical reference.
These Photon Detector channels are for PREX/CREX running conditions:
| Slot | Cha | HV | |
|---|---|---|---|
| Side (V) Finger | SL-6 | CH-10 | -950 V |
| Top (H) Finger | SL-6 | CH-11 | -1000 V |
| GSO (PhDetector) | SL-12 | CH-11 | See note 1 |
Note 1: For PRex the GSO is in an independent HV supply, set to -2340 V.
In addition, there are four scintillators in the laser table, two upstream and two downstream of the interaction point. Note: The following voltages are all positive.
| Slot | Channel | HV | |
|---|---|---|---|
| DS Top | SL-9 | CH-0 | +1800 V |
| DS Bottom | SL-9 | CH-1 | +1800 V |
| US BR | SL-9 | CH-2 | +1800 V |
| US BL | SL-9 | CH-3 | +1800 V |
