Much research is being performed in order to characterize the charging of spacecraft materials. The importance and applications of this research is numerous and especially useful to the development of satellites1. The USU Materials Physics group is currently performing research in this field related to electron emission for spacecraft materials1. This includes testing sample material in an ultra high vacuum chamber. A problem encountered in this testing is that negative charge can build up on the sample material and modify the electron emission measurements2. To remedy this problem, my senior project was to develop, install and test a pulsed system for the optical discharge of thin-film insulating samples. The project included testing the wavelength, intensity and percent transmission of multiple LED’s and coating LED’s with a vacuum safe epoxy.
