不同带电情况下介质材料二次电子发射特性研究
Study of Characteristic for Secondary Electron Emission of Dielectric with Different Surface Chargings
摘要
Abstract
The secondary electron emission (SEE) process is very important for space‐craft surface charged rate and balanced potential .The SEE coefficients (δ) of kapton , cover glass and optical solar reflector (OSR) materials were measured with 1‐5 keV pulsed electron irradiation ,and the SEE yield of dielectric material with different surface charges was investigated .The results indicate that the SEE yield is observed to be lar‐ger at lower projectile energy in the region of 1‐5 keV .The SEE coefficients decrease with positive charging of dielectric when δ is more than 1 and increase with negative charging of dielectric when δ is lower than 1 .关键词
