Description

technical field [0001] The invention relates to the technical field of space radiation detection, in particular to a space radiation detection device and method. Background technique [0002] In the space station, the astronauts are inevitably exposed to the space radiation environment in the cabin. The space radiation environment will cause damage to the spacecraft and astronauts in the space mission, and even lead to the failure of the space mission. With the development of space missions towards long-term deep space exploration, more and more attention has been paid to the cumulative radiation damage of space charged particles and neutrons, so the detection of space protons and other charged particles and neutrons is particularly important. Space radiation contains a variety of radiation particles, and the composition, effect and damage characteristics of different radiation particles are different. Therefore, traditional space radiation detectors need separate systems fo...

AI Technical Summary

Problems solved by technology

Space radiation contains a variety of radiation particles, and the composition, effect and damage characteristics of different radiation particles are different. Therefore, traditional space radiation detectors need separate systems for the detection of charged particles, fast neutrons, thermal neutrons and gamma rays. It is impossible to perform composite measurements on charged particles, fast neutrons, thermal neutrons, and gamma rays, and the detection efficiency is low; moreover, the energy resolution of traditional radiation detectors is poor, and energy resolution is a very critical parameter for identifying charged particles , so the particle discrimination ability of traditional radiation detectors is poor, and it cannot meet the detection requirements of different particles
