Looked at the raw output of both HpGe detectors setup in the LDS.
Their names are Zyad and Tareq.
Zyad is a 90+% efficiency HpGe detector.
The HV on both was set to 2200 by slowing increasing the voltage from zero while keeping the detector output DC offset from exceeding 100 mV. Zyad's DC output is very sensitive in the first 500 Volts or so. Ortec's suggested operating voltage for Zyad +3500 Volts and for Tareq +3000 Volts.
HV=0
Noise level increases on Zyad when HV is zero
