Abstract: A nonthermionic cathode glow discharge device comprising an enclosure and means to maintain gas in the enclosure at a predetermined pressure. An anode is mounted in the enclosure or forms a part of a wall of the enclosure. A cathode having a surface directed at a treatment zone is suspended in the enclosure and has an aperture therein in which is positioned a control electrode. The said surface of the cathode may extend longitudinally or may be shaped as a segment of a sphere. By varying the potential applied to the control electrode with respect to the cathode, the focal point of the electron or ion beam and the current of the output beam can be controlled. A third electrode may be provided to surround part of the cathode to act as a screen to minimize unwanted electron emission from the cathode.

The first electron gun consists of a concave cathode and a convex anode, and for the gun with the cathode radius of Rc (mm) the emission current Ie (A) which give the brightness larger than Langmuir limit is in the range as, 0.733Rc−0.5≦Ie≦0.159Rc3+0.35. Rc≦2.5 mm, or 0.733Rc−0.5≦Ie≦0.255Rc3−1.17. Rc>2.5 mm. The second electron gun consist of a flat cathode and a convex anode, and for the gun with a distance between the cathode and the anode of Dac (mm) the emission current Ie (mA) which give the brightness larger than Langmuir limit or the very high Emittance is in the range as, 0.388/Dac−0.046≦Ie≦92.8/Dac+9.28, Dac≧3 mm, or 0.388/Dac−0.046≦Ie≦22/Dac+32.7, Dac 120 μm).
