An on-orbit particle detection and single event effect monitoring system

Abstract

The invention discloses an on-orbit particle detection and single-event effect monitoring system, which integrates the space radiation environment detection and radiation effect monitoring modules into the same system, and can monitor single-event effects while on-orbit Particle information of particle effects (including energy, type and LET value, etc.), which is of great significance for the study of the mechanism of single event effects; the multi-functional integrated design not only meets the needs of multi-type particle detection, but also can detect radiation effects Monitoring is helpful for spacecraft light and miniaturized design requirements.

Description

technical field [0001] The invention belongs to the technical field of space radiation environment detection, in particular to an on-orbit particle detection and single particle effect monitoring system. Background technique [0002] The space radiation environment is the main environmental factor that causes the performance degradation or even failure of spacecraft materials and components. Among them, high-energy charged particles generate a large number of charged particles in the sensitive area of ​​the device, which induces the single-event effect, which causes the phenomenon of single-event overturning, single-event transient, single-event locking and even single-event burnout, threatening the spacecraft on-orbit. Safe and reliable operation. [0003] The study of the space environment is the foundation of the study of radiation effects. At present, the basic principle of space charged particle detection is indirect detection based on the ionization or excitation of ...
