The Application of Jet Spray and Ion Beam Contamination Removal Techniques to Samples From the LDEF Spacecraft

Abstract

Two samples from LDEF experiment M10003-4 were analyzed for molecular and particulate contamination prior to and following treatment with advanced satellite contamination removal techniques (CO2 Gas/Solid Jet Spray and Oxygen Ion Beam). The pre- and post-cleaning measurements and analyses will be presented. The Jet Spray removed particulates in seconds. The low energy reactive oxygen ion beam removed 5000 angstroms of photo polymerized organic hydrocarbon contamination in less than 1 hour. Spectroscopic analytical techniques were applied to the analysis of cleaning efficiency including: Fourier Transform Infrared, Auger, X-ray Photo emission, Energy Dispersive X- ray, and Ultraviolet/Visible. The results of this work suggest that the contamination was due to spacecraft self contamination enhanced by atomic oxygen plasma dynamics and solar UV radiation. These results also suggest the efficacy for the Jet Spray and Ion Beam contamination control technologies for spacecraft optical surfaces.
