Abstract

A digital pulse analysis system is an important diagnostic system in nuclear physics experimental research. In response to the demand for reflecting the particle state in a nuclear physics experiment, we have designed and developed a real-time digital pulse analysis system and applied it to the digital nuclear pulse waveform discrimination of different detectors in the HL- 2M tokamak. The system is based on the peripheral component interconnect extensions for instrumentation (PXI) platform, while its software was written in LABVIEW. The key technologies involved in the system implementation include digital pulse analysis technology, digital discrimination technology, pulse height analysis technology, etc. The system has been applied to the plastic scintillator detector at the Neutron Source Lab of the University of Science and Technology of China. And the experimental results indicate that the system can discriminate between neutron (n) particles and gamma (γ) particles well when used to measure the plastic scintillator detector.
