AbstractOutgassed molecular contaminants, which are emitted from a spacecraft and which can subsequently deposits on sensitive surfaces, might impart adverse effects on sensor performance and thermal characteristics. We evaluated the contamination environment of the Optical Telescope Assembly (OTA) onboard the SOLAR-B (Solar Physics Satellite: HINODE) spacecraft. Especially, the primary and secondary mirrors were evaluated along with a Collimating Lens Unit (CLU) for elucidation of the contamination environment. The calculated results satisfied the SOLAR-B project's requirements. After the SOLAR-B was launched on September 22, 2006 UT, telemetry data of the OTA became available. As the temperature of the Heat Dump Mirror (HDM) rose above the expected levels, the primary and secondary mirror, and the HDM were evaluated for molecular contaminants accumulation and the solar absorptance. Analytical results of both primary and secondary mirror were roughly corresponding to demand value of SOLAR-B project. For the HDM analytical results of the solar absorptance were less than a result of telemetry data conversion.
