Ik. Kurkan et al., A POSSIBLE METHOD OF REDUCING THE MAGNETIC-FIELD IN A RELATIVISTIC BACKWARD-WAVE TUBE, Technical physics letters, 24(5), 1998, pp. 388-389
A new configuration is proposed and implemented for a relativistic bac
kward-wave tube using the symmetric TM01 mode which can appreciably en
hance, by a factor of 2-3, the generation efficiency of high-power 3 c
m radiation pulses using low magnetic fields. (C) 1998 American Instit
ute of Physics. [S1063-7850(98)02505-1].
