A high-power vircator that is based on the Korvet ironless linear induction
electron accelerator built around radial pulse-forming lines is implemente
d for the first time. Results on the computer simulation and experimental o
ptimization of the vircator are discussed. The experimentally found paramet
ers of the vircator are the following: cathode current 35 kA (at a limit cu
rrent of 19 kA), microwave pulse base widths 40 and 18 ns, and peak microwa
ve power more than 500 MW. (C) 2001 MAIK "Nauka/Interperiodica".
