Simulation and Realization of Nuclear Instrument System

For the special nature of the nuclear physics experiment, a NIM-standard nuclear instrumentation system is simulated based on LabVIEW, including plug-ins simulation and integrated devices such as a nuclear random signal generator, a linear amplifier, a single channel analyzer, a scaler and a data-processing module. In order to verify the system, some undergraduate nuclear physics experiments were done. The results show that the simulation signals of the nuclear random signal generator accord with the rule of statistical nature of the nuclear random pulse, the GUI of simulation system is verisimilar, simulation operation is basically the same as real experimental operation. Application of the simulation system has practical significance in mastering conventional nuclear radiation detection methods and avoiding radiation damage of the experiments.
