Compton Calorimeter
The compton calorimeter (CompCal) is an array of 12x12 PWO modules. Light from each module is detected using Hamamatsu R4125 photomultiplier tube, which is operated at the typical HV of 800 V.
Routine operation
The shift workers will need to monitor the CompCal performance using the CSS monitoring GUIs described below. The following parameters have to be checked during routine operation of the CompCal detector: temperature, high voltages, and occupancy plots.
The following instructions are for non-experts during routine operation. Operations beyond what is specified here shall only be performed by the system expert or under his/her direction. If the expert directs an operation outside the ones described here, a specific note must be entered into the log book.
Expert personnel
The individuals responsible for checking that the CCAL is ready to take data and setting its operating parameters are shown in following table. Problems with normal operation of the CCAL should be referred to those individuals and any changes to their settings must be approved by them. Additional experts may be trained by the system owner and their name and date added to this table.
