Description

technical field [0001] The invention relates to the field of nuclear energy spectrum measurement and analysis, in particular to a nuclear energy spectrum processing method and equipment. Background technique [0002] Nuclear radiation refers to radiation with one or more energies emitted by radioactive sources or radiation devices in the form of waves or particles, such as α-rays, β-rays, γ-rays, X-rays or neutrons. Since nuclear radiation has important applications in many fields such as military, industry, agriculture, medical and health, scientific research, environmental protection, public safety, etc., the measurement and analysis of nuclear energy spectrum that can reflect the energy distribution of nuclear radiation is very important. [0003] At present, the key technical indicators affecting the measurement and analysis of nuclear energy spectroscopy include relative energy resolution and pulse passing ability. Among them, the relative energy resolution is defined ...

AI Technical Summary

Problems solved by technology

[0004] The existing nuclear energy spectrum measurement technology mainly adopts the nuclear pulse processing technology with the priority of signal-to-noise ratio, and the pulse passing ability is poor.

Although some nuclear spectrometry analysis techniques use speed-prioritized spectrometry techniques, they do not solve the problem of energy resolution degradation

At present, in the processing of nuclear energy spectrum, the two key technical indicators, the energy resolution representing the accuracy and the pulse passing ability representing the speed, are mutually restricted, which cannot meet the high-performance measurement and analysis of nuclear energy spectrum at a high pulse count rate.
