O-atoms were generated by injecting molecular oxygen into a preionized argon plasma. A mixture of argon plasma and oxygen was expanded through a sonic orifice into a low pressure chamber as a free jet. To confirm the generation of O-atoms and to examine the possibility of forming a molecular beam from the supersonic free jet, population densities of the electronic excitation levels 3p3P and 3p5P of atomic oxygen were measured along the free jet centerline. The results show that the population densities satisfied the flux condition of low earth orbit., 資料番号: NALTR0989000, レポート番号: NAL TR-989}, title = {An Atomic Oxygen Generation Facility for Space Environmental Testings}, year = {1988} }
