Abstract Feasibility of atomic oxygen concentration using reflecting mirrors was studied. Pyrex was selected as a material of reflecting surface due to its low recombination yield of atomic oxygen. Efficiency of reflection at Pyrex surfacewas measured to be 87.1%. The focal point of atomic oxygen reflected by a concave mirror was predicted by a computer simulation based on Hard-Cube model. It was estimated from the computer-simulated results that the difference between incident and exit angles of atomic oxygen due to energy loss during inelastic scattering event was evaluated to be at most 5 degrees depending on the incident angle. The computational results on trajectories of atoms scattered at the Pyrex concave mirror were compared to experimental results, and good correlation was observed. A high-efficiency atomic oxygen concentrator is designed based on the experimental results reported herein.
