Abstract
A source of atomic oxygen and halogen negative ions is described. The ions are generated by secondary ion emission from a target made of met al oxide or a halogen salt. The cathode target is bombarded by positiv ely charged ions produced in a gas discharge. For O-, Cl-, and F- ions the current of a beam 1 mm in diameter was approximately 0.1 muA. The ion energy dispersion was no more than several electronvolts, and the content of other ion impurities was a few percent.
