Main dAOM Functions
- PMT power supply
- High voltage (HV) for the PMT is generated using a special designed DC-to-HV converter
- Communication with the DAQ system at the surface
- Analog pulse transmission via optical fiber and electrical copper cable
- Slow control functions:
- Setting the HV for the PMT
- Setting the gain for the analog signal transmission to the surface
- Setting the bias current for the laser diode in the optical signal transmission path
- Monitoring:
- the Temperature inside the dAOM
- Actual HV level (anode and last dynode) and status (on/off)
- Supply voltage levels (+5V)
