Abstract:
The invention relates to the field of fabrication of new materials and coatings and may be used in plants designed for electron-beam heating, melting and evaporating of materials in vacuum or reactive gas atmosphere. The disclosed axial electron gun that comprises, in particular, the primary and secondary cathodes and features the figure-shaped holder used for maintaining a stable position of the secondary cathode relative to the electron-beam axis of the axial gun and the pulsed voltage that is applied between the cathodes for electron bombardment of the secondary cathode. The invention ensures an improved stability of process parameters and operation of the electron gun.

Claim (Index 1):
An axial electron gun comprising a primary cathode, a secondary cathode, an accelerating anode, a beam guide, a focusing coil, a deflecting system, a power supply system and a vacuum system characterized in that a figure-shaped holder of the secondary cathode is made of polycrystalline tungsten wire in the form of a plane regular triangle, quadrangle, pentagon or hexagon that put in an ring groove on the cathode's cylindrical side surface.
