Av. Batrakov et al., SOURCES OF PULSED LOW-ENERGY-ELECTRON BEAMS AND SOFT X-RAYS BASED ON LIQUID-METAL EXPLOSIVE-EMISSION CATHODES, IEEE transactions on plasma science, 25(4), 1997, pp. 714-717
This paper describes a pulsed electron beam source with a liquid-metal
cathode operating in the explosive-electron-emission mode, The operat
ing voltage range of the source is 10-40 kV, The operating frequency o
f the cathode is up to 1500 Hz. The device can be used as a point elec
tron source in various electronic tubes and as an element of a multi-e
mitter electron source producing a large-cross-section electron flow.
