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.
The power supply is connected to a spark protection circuit. CAEN N470 has a signal Lemo 00 input to activate a kill option automatically when a discharge signal is created through the detector operation, the kill input is connected to the the detector readout plate, as a discharge happens and it is wider than 15 us, Kill option state turns true, so it will trip all the power supply channels.
