利用空间电荷测量系统对航天器太阳光学反射镜用氟化材料进行了电子束辐照后的直流高应力下的空间电荷测量。结果表明，在直流高应力下，经电子束辐照的乙烯-丁二烯和氟化乙烯-丙烯共聚物中积累了大量的空间电荷，而未辐照的乙烯-丁二烯和氟化乙烯-丙烯共聚物中未观察到空间电荷。在该报告中，还研究了照射后的弛豫时间对空间电荷累积特性的依赖性。
Electron beam irradiated fluorinated materials, which are used for an optical solar reflector of spacecraft, have been investigated using a space charge measurement system under dc high stress. It was found that a large amount of space charge accumulated in the electron beam irradiated ethylene‐tetrafluoroethylene and fluorinated ethylene‐propylene copolymer under dc high stress, while it was not observed in nonirradiated them. In this report, a dependence of relaxation time after the irradiation on the space charge accumulation characteristics was also studied.
