The Resistive-Wall Amplifier

Circuitless electron beam amplifier (CEBA)

“…In general, the dielectric constant of the plasma in a longitudinal magnetic field is not isotropic, and Gr in alt transverse directions is given by Equation (3) and is given by Equation (2) in the propagation direction. However, under specialized conditions, the authors were able to characterize an electron beam as having an isotropic permittivityO, and permeabilitywhere4 andeo are both given by Equation (3).…”

“…Over past years, attempts have been made to build microwave oscillators and amplifiers which did not require an RF slow wave circuit, i.e., such devices as the scalloping beam amplifier, 1 the double stream amplifier, 2 and the resistive wall amplifier. 3 These devices were abandoned because the conventional devices such as the klystron, magnetron, and TWT demonstrated superior performance characteristics. Perhaps, however, it is time to reconsider the circuitless devices for mm wave operation because of their inherent simplicity.…”

<title>Influence of dissipation on overlimiting electron beam instability in microwave sources</title>

“…Dissipative instability of electron beam underlies on the operation of so-called amplifier on dissipation. The idea of such a type of amplifier was proposed comparatively long ego [15] and was developed further. Dissipative instability of overlimiting electron beams has not been considered yet.…”

Dissipative instability of overlimiting electron beam

“…Physical instabilities of electron beam underly on the operation character of their instability is due either to aperiodical of so-called amplifier on dissipation. The idea of such a modulation of the beam density in medium with type of amplifier was proposed comparatively long ego negative dielectric constant [1,3] or to excitation of and was developed further [9]. It has some characteristic beam pace charge wave with negative energy.…”
