标题: Protection of materials and structures from space radiation environments on spacecraft
摘要: 

Spacecraft in orbit will encounter space radiation environments such as electron, proton, heavy ions, gamma ray, etc, and results in space radiation effects such as single event effects, total ionizing dose effects, displacement damage effects, surface charging and discharging or electrostatic discharging, internal charging effects, so protection from space radiation should be given to the spacecraft. The protection principle and validity from space radiation environments on spacecraft is introduced firstly, and then from three dimensions such as material, subsystem and spacecraft, protection materials and structures such as mass shielding material, ESD protection material, radiation hardening functional material, local protection structure, whole-spacecraft protection structure, are discussed. At last, some development directions on protection material and structure from space radiation environments are proposed.
Keywords: space radiation environment; protective material; protective structure; spacecraft
