    Abstract: 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.

    Abstract: The invention relates to a device for producing an electron beam, comprising a housing (12), which delimits a space (13) that can be evacuated and has an electron beam outlet opening; an inlet (16) for feeding a process gas into the space (13) that can be evacuated; a planar cathode (14) and an anode (15), which are arranged in the space (13) that can be evacuated and between which a glow-discharge plasma can be produced by means of an applied electrical voltage, wherein ions can be accelerated from the glow-discharge plasma onto the surface of the cathode (14). The cathode has a first part (14a) made of a first material, which forms a centrally arranged first surface region of the cathode (14), and a second part (14b) made of a second material, which forms a second surface region of the cathode (14) that encloses the first surface region. The first material can be heated by the impingement with accelerated ions to a temperature at which electrons escape the first material predominantly due to thermionic emission.

    Abstract: A voltage regulator circuit for an electron microscope incorporates step-down and step-up transformers connected between the filament supply and the filament of a regulator triode. The triode has a cathode separate from the filament, the cathode being connected to the center-tapped primary of the step-up transformer. A magnification-reducing resistor may be connected across the grid and cathode of the triode.
