摘      要：Photomultiplier tube(PMT)has been an essential instrument for low background experiments,and the accuracy of single photoelectron(SPE)calibration will directly affect the energy reconstruction of the *** SPE spectrum can be acquired from the charge distribution of dark-noise pulses or the low-intensity light signal triggered by ***,there are arguments on whether the two methods are *** this paper,the Hamamatsu R5912-20mod PMT and the EMID642KNFL PMT have been tested adopting the two methods with signal waveform recording *** comparison,traditional charge-to-digital conversion system is also used to test SPE *** results show that they are consistent when the PMTs are working at typical recommended high voltage(HV).
