    摘要： A charged particle beam column assembly for mounting to an evacuated charged particle beam source chamber. The assembly has a sequence of controlled pressure chambers (55-57), each having inlet and outlet apertures (51A-54A) through which a charged particle beam can pass and an evacuation port (59) for connection to a pump to enable the pressure in the chamber to be controlled. The pressure in successive chambers (55-57) increases in use. An evacuation port (59) is connected to a downstream chamber via a conduit (145,146) which extends within the assembly past at least one upstream chamber.

    摘要： A charged particle emitting assembly comprises an emitter member (5) for emitting charged particles of one polarity. A tubular shield electrode (6) circumferentially surrounds the emitter member and is held in use at the same polarity as the charged particles. A tubular accelerating electrode (7) is positioned substantially coaxially with the shield electrode (6) and is held in use at the opposite polarity to the shield electrode. The arrangement is such that charged particles from the emitter member (5) initially spread laterally outwardly and then are focused into a beam which passes through the tubular accelerating electrode (7).

    摘要： An electron gun cathode (104) is column shaped, and emits electrons by being heated. A holder (103), which covers the bottom and sides of the electron gun cathode, has electrical conductivity and holds the electron gun cathode, and is composed of a material that does not easily react with the electron gun cathode when in a heated state, is provided. The tip of the electron gun cathode (104) protrudes from the holder (103) so as to be exposed, and electrons are emitted from the tip toward the front by applying an electric field to the tip.
