Inordertostudytheatomicoxygencorrosionofspacecraftmaterialsinlowearthorbitenvironment,anatomicoxygensimulatorwasestablished.Inthesimulator,a2.45GHzmicrowavesourcewithmaximumpowerof600WwaslaunchedintothecircularcavitytogenerateECR(electroncyclotronresonance)plasma.TheoxygenionbeammovedontoanegativelybiasedMoplateundertheconditionofsymmetrymagneticmirrorfieldconfine,thenwasneutralizedandreflectedtoformoxygenatombeam.Thepropertiesofplasmadensity,electrontemperature,plasmaspacepotentialandionincidentenergywerecharacterized.TheatomicoxygenbeamfluxwascalibratedbymeasuringthemasslossrateofKaptonduringtheatomic5～30eVandacrosssectionofφ80mmcouldbeobtainedundertheoperatingpressureof10-1～10-3Pa.Suchahighfluxsourcecanprovideacceleratedsimulationtestsofmaterialsandcoatingsforspaceapplications.
