Integrated radiation effect detector for three-dimensional high-energy particles

Abstract

The invention provides an integrated radiation effect detector for three-dimensional high-energy particles. The detector comprises an LET spectrum detector, a radiation dose detector, a different potential detector, a digital data collection circuit, a data processing unit and a communication module; the LET spectrum detector, the radiation dose detector and the different potential detector measure the particle radiation LET spectrum, the radiation dose and the satellite surface different potential respectively, a generated voltage signal is converted into a digital signal by the digital signal collection circuit, and the digital signal is output to the data processing unit, the data processing unit analyzes the voltage amplitude and trend of the digital signal, data reflecting the LET spectrum, the radiation dose and the satellite surface different potential information is obtained, and the data processing unit makes data interaction with a satellite after being connected to the satellite via the communication module. According to the detector, three independent space detection functions are integrated to detect different indexes of the space environment in an integrated manner, the integrated degree is improved, and the cost and weight are reduced.

Description

technical field [0001] The invention relates to the field of comprehensive measurement of space radiation LET spectrum, radiation dose and surface potential, in particular to a three-dimensional high-energy particle radiation effect comprehensive detector. Background technique [0002] In order to solve the problem of environmental failure of my country's spacecraft in orbit, it is necessary to systematically solve it from the environment-effect-protection research value system. First of all, it is necessary to master the mechanism and characteristic laws of the radiation environment and effects, carry out targeted engineering design, and conduct ground test verification and on-orbit verification, and finally form design specifications and protection design evaluation specifications, so as to ensure high reliability and long life of the spacecraft. in orbit.
