DSG HPGe Maintenance Check Sheet

Maintenance check / pretest

Ge detectors may operate at bias voltages of 5000 V DC or more.
Always be sure that detectors are properly grounded (through the SHV
coaxial cable ground to a properly grounded Power Supply/NIM Bin).
Also use extreme caution when adjusting internal preamplifier controls to
avoid contact with the high voltage circuit.
Connect the Oscilloscope with a BNC cable or BNC T-fitting (picture 1)
on the main amplifier OUT (picture 2 - picture 4).
