Optical measurement of contaminant concentrations for precision cleaning applications
Abstract
The goal of this research was to develop methods of measuring concentrations of contaminants present in spacecraft processing environments. Two projects were directed at measuring amounts of nonvolatile residue (NVR) present in precision cleaning solvents, where NVR is material which remains after evaporation of the sol vent. These sol vents are used to clean components of spacecraft hardware. A measure of NVR is necessary to determine if the components have been sufficiently cleaned. A third project was directed at developing infrared laser photoacoustic to determine airborne contaminant concentrations. The contaminants studied, if present inside the spacecraft, can damage payload optical systems when deposited on their surfaces. contaminant detection method is necessary to measure the concentrations when the exposure occurs in order to prevent damage which otherwise may not be known until after the payload has been launched.
