A hyperthermal atomic oxygen beam was generated by a laser detonation-type atomic oxygen beam source. In-situ mass loss measurement was made during the atomic oxygen exposure using a quartz crystal microbalance. It was observed that the erosion rate of polymers was followed cosine function with respect to the incident angle of atomic oxygen. This experimental finding clearly indicates that the reaction yield of atomic oxygen with polymers is independent of the incident angle. As for the fluence monitoring material, erosion depth or mass loss of polyimide simply reflects the effective atomic oxygen fluence which is calculated by multiplying normal flux and cosine of the incident angle., 資料番号: AA0063585016, レポート番号: JAXA-SP-06-035}, pages = {91--94}, publisher = {宇宙航空研究開発機構, Japan Aerospace Exploration Agency (JAXA)}, title = {Erosion characteristics of polyimide used as a material for measuring oxygen atom environments}, volume = {JAXA-SP-06-035}, year = {2007} }
