ABSTRACT:
An ion beam apparatus with an ion gun in which a gas to be ionized is supplied to the periphery of an emitter and a high voltage is applied between the emitter and an extractor so that the gas introduced to the vicinity of the emitter tip is ionized to generate an ion beam. The structure of the ion gun is formed so as to achieve a high ion current density of the ion beam as well as to prevent short-circuiting that may otherwise be caused by atmospheric electric discharge between the emitter and the extractor.
