Resistive wall amplifier

WAVE PROCESSES IN THE ELECTRON BEAM IN CROSSED STATIC ELECTRIC AND MAGNETIC FIELDS AS IT MOVES IN A MEDIUM WITH A COMPLEX CONDUCTIVITY

Resistive wall amplifier is vacuum microwave device. The gain is due to the phase shift between a.c. of electron beam and the alternating field components. The absorbing device walls influence on the alternating field components is considered. It is interesting that there is no need for a slowing system that is important to learn the submillimeter range. Furthermore the feedback is completely absent between the output and the input.

ABOUT CONSIDERATION OF ELECTRON TRANSVERSE MOTIONS IN RESISTIVE WALL AMPLIFIER

Resistive wall amplifier is a vacuum microwave device, which has not been spread, but attracts attention again. Main features – no need to slow-wave structure and almost complete lack of feedback between output and input. The amplification occurs due to the phase shift between the electron beam and field variables that arise due to the presence of absorbing walls.
