Detector operation

Operating the detector occurs by providing voltage to the HV-circuit connected to the detector components mentioned in the previous section. A CAEN N470 four channel power supply is used for this purpose, using a channel of the power supply allow to increase the voltage difference between the top and bottom side of the GEM preamplifier reaches up to 350 V as the circuit board is provided with a voltage of 2.8 kV.

Another channel of the power supply is used to increase the voltage of the Cathode, when the cathode voltage is 3.1 kV, it will create a a drift voltage up to 300V.
