Nuclear pulse signal generating method and nuclear pulse signal generating device

Abstract

The invention provides a nuclear pulse signal generating method and a nuclear pulse signal generating device. The nuclear pulse signal generating method is characterized in that a nuclear pulse signal amplitude random distribution function can be acquired; a waveform function of a single nuclear pulse signal can be acquired; a nuclear pulse signal time interval random distribution function can be acquired; digital nuclear pulse signals can be generated by the waveform function of the single nuclear pulse signal and the nuclear pulse signal time interval random distribution function; the digital nuclear pulse signals can be converted into the simulation nuclear pulse signal, which can be output. The method is advantageous in that by adopting the nuclear pulse signals generated by the radioactive source and the detector in a combined manner by adopting the electronic way, the time characteristic, the amplitude characteristic, and the pulse shape characteristic of the nuclear pulse signals can be guaranteed, and then the real nuclear pulse signals can be simulated in the scientific research and teaching process, and therefore the radioactive harm caused by the generating of the nuclear pulse signals by the radioactive source can be prevented.

Description

technical field [0001] The invention relates to the technical field of signal generation, in particular to a method and device for generating a nuclear pulse signal. Background technique [0002] Since Becquerel discovered the natural radioactivity of uranium in 1896, human beings have started to study nuclear science and technology. Nuclear technology and its application have developed rapidly in the past 100 years, especially in recent decades. Extended, it has been used in various fields such as physics, medicine and life sciences, environmental sciences, energy, industry, agriculture and social security. [0003] Particle accelerators, nuclear detection and nuclear electronics, radiation and particle beam technology, radionuclide technology, etc., are usually collectively referred to as nuclear technology. [0004] Because nuclear applications require radioactive sources, and radioactive sources contain radiation, improper protective measures or violations of operating ...

AI Technical Summary

Problems solved by technology

[0006] Only the pulse shape can be output, and the physical characteristics of the radioactive source cannot be simulated, such as energy distribution information, particle type information, detector response information, etc.

In addition, only pulse signals with consistent amplitude can be given, and pulse signals with randomness in amplitude cannot be given. Only periodic pulse signals can be output, and pulse signals with randomness in time cannot be given.

[0007] In short, the nuclear pulse signal output by the nuclear pulse signal source in the prior art cannot truly reflect the physical characteristics of the nuclear pulse signal output by the radioactive source, and it is difficult to meet the needs of nuclear technology research
