Abstract
A composite explosive emission cathode for generating large-diameter e lectron beams has been fabricated from LaB6-TiB2 produced by self-sust aining high-temperature synthesis. Electron microscope studies of the emitting surface indicate that the height of micropoints is 2-13 mu m, their base diameters are 5-13 mu m, and their density is 2 . 10(6) cm (-2) Cathode emission characteristics measured at the OMEGA-350 accele rator are compared to those of a steel emitter.
