ABSTRACT:
An electron generating apparatus for an ion source for example, which is capable of prolonging service life and facilitating the exchange of its filament has been proposed. The electron generating apparatus includes an electron generating chamber having a discharging gas supply hole and electron extracting hole, a pair of conductive filament support members mounted in the chamber through an insulating plate, and a filament detachably fixed on the filament support members. At least one of the filament support members is provided with an overhang to cover at least part of a region between the lower ends of the filament.
