| Abstract: | The contaminant collection and component identification tests were performed during the thermal vacuum tests.The witness plate was used to collect deposits,which was solved by acetone.The solution was analyzed by using GC/MS to identify compositions of the contaminants.Phthalate and siloxane were identified as the main contaminants in satellite thermal vacuum tests and solar array thermal vacuum tests.Possible source of methylphenylsiloxane in solar array thermal vacuum test may come from solar cell adhesive. |
