✦ Synopsis

In describing various types of plasma-cathode electron sources, we distinguish them mainly by the shape (configuration) of the generated electron beam, which is responsible in many respects for the functional capabilities of the beam. We distinguish between axially symmetric electron beams, such as cylindrical, including focused, and hollow or tubular beams, and also large-cross-section and ribbon electron beams. To produce an electron beam of one or the other configuration, various kinds of discharges or their combinations are used. Depending on the desired electron-beam parameters, the discharge system can be designed to operate in either pulsed or continuous mode.
