keyword=L-HRS: Reduce HV of PRL2 #15counterThe PRL #15 has much ADC values by comparing with other counters next to it. I checked the HV of it and found that it is about 150V higher than others. Also, the #ADC channles of S.P.E peak is almost double than others. Hence, I decide to reduce its HV from -1020V to -940V by reducing S.P,E from about 600 channles to 300 channles.
