Abstract
The inf1ere of simulated space environment on the prcpert ies of the satel 1 i te temperature-control coat ing --- Optical Sol ar Ref1etor (OSR) is discussed. I kinds of CSR sample are tested in the simu1at1 space environment . The simulat ion i tens include vacuum US? irradi at on, electron and proton i rradiat ion . The surface charge/discharge test is carried out tcx . After the ecron, proton and UV accelerat ive irradiat ion of total dosage equivalent to 7 years at the south or north pale of geosyixthrcrx,us satellite, the solar aI:sorptaire increases from 0 .068 to 0 . 078 for cczxkt ive C , and from 0 . 066 to 0 . 085 for ncn-oonduct ive OSR; the normal ni ttance decreases from 0 .83 to 0.72 for conditive OSR, and from 0.82 to 0.76 for non-conductive OSR. Also, it is shown from the charge/discharge test that the surface charge potential is only I5--40 V for conduct ive CSR, and about 1 --1 0 Ky for non-conduct ive CSR.
