    Abstract: An ion source device includes an electron generating chamber detachably combined with an electron attraction electrode and an ion generating chamber through insulating members. Hooks are projected from both sides of the electron generating chamber. A holder plate is arranged under the ion generating chamber with an insulating member interposed between them. A fixing member is arranged under the holder plate. The fixing member includes a pusher supported by coned disc springs and this pusher of the fixing member is fitted into a recess on the underside of the holder plate and struck against the top of the recess. A pair of holder members are arranged along both sides of the device. The holder members are detachably engaged with the hooks of the electron generating chamber at the upper portion thereof and also detachably engaged with the fixing member at the lower portion thereof. The components ranging from the electron generating chamber to the holder plate are held and fixed between the hooks of the electron generating chamber and the pusher of the fixing member through the holder members.

    Abstract: An electron gun for use in electron irradiation equipment. The gun comprises a cartridge including a Wehnelt electrode and a filament with two plug electrodes mounted on an insulating plate. The filament is mounted between the Wehnelt electrode and a conductive plate by two fasteners and can be adjustably aligned with respect to the Wehnelt electrode by moving the electrode with respect to the filament before the mounting is made fast. The electrical potential supply terminal has two jacks which receive the plug electrodes thereby mechanically and electrically coupling the cartridge to the potential supply and the Wehnelt electrode receives its potential through a resilient contact on the potential supply terminal.

    Abstract: Examples of an electron gun with a moving cathode station and a moving anode station are described. The moving cathode has a driver that moves the station and comprises a plurality of cathodes with a plurality of bias cups to control a thermal electron emission region by applying a bias voltage to the bias cup. The moving anode station comprises a plurality of anodes and has driver to move the anode station such that a position of each anode is synchronized with a positioned of a respective matching pair of cathode and bias cup. A controller that is in communication with the anode and cathode moving stations controls the bias voltage and the drivers to control the amount of thermal electrons and to synchronize and align a predetermined cathode with a predetermined anode thus controlling the size and parameters of the generated electron beam.
