Abstract
A multisectional explosion-emission cathode is described for generation of electron beams with large cross-sections. The cathode sections are fabricated on the base of chemical compound LaB6-TiB6, obtained by the method of self-propagating high-temperature synthesis. Results of electron microscopy of an emitting section surface show that the micropoint height is 2-13 μm, the base diameter is 5-6 μm, the surface density of micropoints is >2·106 cm-2. Experimental results on determination of the cathode emission characteristics are presented in comparison with a steel emitter.
