[0002] In the field of radiation detection and particle screening, selecting different particle detectors according to actual scenarios and using various nuclear instruments with data acquisition to complete particle screening tasks is a common test method in various experiments, but because of different Types have different response principles to neutron gamma signals, the required discrimination algorithms are also different, and the corresponding front-end readout systems are also different, so various customized systems are often required in actual measurement

[0003] Generally speaking, the quality of the particle screening algorithm is very dependent on the selection of the screening parameter value, and repeated testing to find the target screening parameter value matching the detector is a kind of repetitive work, which will consume a lot of time. When it is necessary to change the readout circuit During design, the corresponding target screening parameter values ​​may change, which will bring more energy consumption to the debugger
