摘要

航天器表面材料的二次电子发射(SEE)、光电子发射(PE)等介电特性对航天器的高可靠性发电是有要求的。这些材料由于轨道上的放射性射线照射而变质。这些值可能会随情况而改变。为了准确估计卫星寿命终止时的地表变化,需要给出卫星寿命终止时的PE和SEE值。在本报告中,我们将质子束照射到绝缘材料上,并测量了老化样品的PE。我们研究了辐照剂量与PE之间的关系。

Photoelectron Emission on Polyimide Films Irradiated by Proton
The dielectric characteristics of the surface material of the spacecraft, such as secondary electron emission (SEE) and photoelectron emission (PE), are required for high reliability of spacecraft generation. Those materials are deteriorated due to radioactive rays irradiation on orbit. Those values may be changed from the situation. When we want to estimate surface changing at the end of life (EOL) of satellite with accuracy, we need to give values of PE and SEE at EOL situation. In this report, we irradiated the proton beam to insulating materials and measured PE on the aged sample. We examined the relationship between the irradiation dose and PE.
