High-average-power CW FELs for application to plasma heating designs and experiments
(IEEE, 1990)
A short-period-wiggler (period - 1 cm), sheet-beam FEL has been proposed as a low-cost source of high-average-power (1 MW)
millimeter-wave radiation for plasma heating and space-based radar applications. Recent calculations ...
Wiggler focused relativistic sheet beam propagation in a planar free-electron laser configuration
(Copyright 1989 American Institute of Physics. This article may be downloaded for personal use only. Any other use requires prior permission of the author and the American Institute of Physics., 1989-11-13)
The propagation of a relativistic sheet electron beam through a spatially periodic magnetic
field (wiggler) has been studied experimentally. The wiggler serves two purposes; it provides
beam focusing as well as the ...
Demonstration of efficiency enhancement in a high-power backward-wave oscillator by plasma injection
(American Physical Society, 1989-05-15)
An experimental demonstration of a strong enhancement of the interaction efficiency in a high-power
relativistic backward-wave oscillator when plasma is injected is presented. Controlled plasma injection
enhances the ...

Observation of a resonant enhancement of microwave radiation from a gas-filled backward wave oscillator
(American Institute of Physics, 1988-08-15)
High-power microwave radiation at 8 GHz from a gas-fined backward wave oscillator driven
by an intense relativistic electron beam has been measured. It has been observed that an order
of magnitude resonant increase in ...
Experimental high power plasma-filled backward wave oscillator results
(Institute of Electrical and Electronics Engineers, 1988-06)
High power plasma filled backward wave oscillators
(SPIE, 1988-01)
Relativistic backward wave oscillators (BWOs) have proven to be relatively efficient,
high-power microwave sources in the centimeter wavelength range. Recent Soviet results
have indicated that the use of a background ...
Experimental demonstration of an electromagnetically pumped free-electron laser with a cyclotron-harmonic idler
(American Physical Society, 1988)
A three-wave, free-electron laser was operated with a powerful 8.4-GHz electromagnetic "pump"
wave replacing the usual magnetostatic wiggler. The presence of a uniform axial magnetic field Bo produced
cyclotron-harmonic ...
