[0001] The invention relates to the technical field of single photon detection, and specifically discloses a nuclear imitation pulse generating device and a method thereof. Background technique [0002] The simulated nuclear pulse can simulate the time and amplitude characteristics of nuclear signals, and is widely used in major nuclear signal research laboratories, factories, and geological surveys. The simulated nuclear pulse signal can be used to calibrate various nuclear particle detection and energy spectrum equipment, and provide a signal source for the development of nuclear signal processing systems. The decay of radionuclides is random in time, and the statistical characteristics of the nuclear energy level make the rays produced by the decay also have randomness in energy, which is specifically manifested in the pulse corresponding to the nuclear radiation of a single energy, which basically conforms to the Gaussian distribution in amplitude , which conforms to an ex...
