Relativistic backward wave oscillators: Theory and experiment
(IEEE, 1991)
Microwave sources based on backward-wave oscillators
with relativistic electron beams are capable of producing
high power coherent radiation in the cm and mm wavelength
regime. Although there have been a number of ...
Experimental development of a millimeter wave free electron laser
(SPIE, 1990-12)
A 1 MW (cw), millimeter wave FEL (X, « 0.5 mm) is currently under development with an application for heating
fusion plasmas. Two salient features of the FEL are the use of a short-period wiggler £w < 10 mm) electromagnet
and ...

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 ...
Experimental studies of high power plasma filled backward wave oscillators
(IEEE, 1990-05-21)
Summary form only given, as follows. It has previously been demonstrated that a plasma-loaded backward wave oscillator (BWO) powered by a relativistic electron beam can generate hundreds of megawatts of microwave radiation ...

Detailed experimental studies of a collective acceleration experiment in which a time sequenced
laser-generated ionization channel is used to control the propagation of an intense
relativistic electron bearnfront are ...
Shielded-source, short-pulse microwave propagation experiments
(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., 1989-08-01)
The propagation of short-pulse, high-power microwaves through a neutral gas has been studied
and breakdown limits determined in an experimental configuration in which the neutral gas
test cell was carefully shielded from ...
Measurements and simulation of controlled beamfront motion in the laser controlled collective accelerator
(Institute of Electrical and Electronics Engineers, 1989-03)
In the Laser Controlled Collective Accelerator, an intense
electron beam is injected at a current above the vacuum space
charge limit into an initially evacuated drift tube. A plasma
channel, produced by time-sequenced, ...
Free electron laser with small period wiggler and sheet electron beam: A Study of the feasibility of operation at 300 GHz with 1 MW CW output power
(1989)
The use of a small period wiggler (Cw < 1 cm) together with a sheet electron beam
has been proposed as a low cost source of power for electron cyclotron resonance heating
(ECRH) in magnetic fusion plasmas. Other potential ...
Short-pulse high-power microwave propagation in the atmosphere
(American Institute of Physics, 1988-02-12)
The propagation of high-power 00-200 kW/cm2
) short-burst (3-30 ns) microwave pulses in
the atmosphere has been studied experimentally. Microwave power from a large orbit gyrotron
operating at 9.6 GHz is focused by a ...
