Self-propagating high-temperature synthesis of the high- current emission lanthanum and niobium contained ceramics

Preserved Fulltext
The paper describes the production of metal-ceramic high-current emitters containing lanthanum hexaboride LaB 6 by self-propagating high-temperature synthesis. Tests of emitters as explosive-emission cathodes in an OMEGA-350 microsecond accelerator are presented. Experiments show that when a metal-ceramic cathode is used, the emitted energy was 12-17 % higher than that produced by tungsten and graphite cathodes and the beam "signature" is a circle with a small (~ 15 %) variation in radius.
