In order to overcome the problem of large volume and poor portability of traditional high-voltage power supply equipment, we used the internal integrated miniaturized high-voltage module to provide high-voltage for PMT in the development of portable pulsed neutron detector. According to the experimental results, the maximum output voltage of the selected high-voltage module can reach 2.5 kV and has good output consistency. It can adapt to 16-36 V working voltage, and has excellent continuous working stability and temperature stability. It can meet the requirements of the development of pulsed neutron detectors.
