Millimeter wave free electron laser amplifiers: Experiments and designs
(1991-08)
Free electron laser amplifiers are investigated as sources of high average-power (1 MW) millimeter to submillimeter wave radiation (200-600 GHz) for application to electron cyclotron resonance heating of magnetically ...
Experimental studies of high-power microwave reflection, transmission, and absorption from a plasma-covered plane conducting boundary
(The American Institute of Physics, 1991-05-01)
Experimental studies of the reflection, transmission, and absorption of high-power microwave
pulses from a plasma-covered plane conducting boundary are presented. Under optimum
conditions, backscattered rf power is ...
Second generation, high-power, fundamental mode large-orbit gyrotron experiments
(American Institute of Physics, 1991-01-15)
Experimental studies of a large-orbit gyrotron device operating at the fundamental of the
cyclotron frequency have been conducted. Based on results of initial investigations at the
University of Maryland a linear beam ...
Studies of ion acceleration in a one meter laser controlled collective accelerator
(Institute of Electrical and Electronics Engineers, 1991)
The basic concept behind the Laser Controlled Beamfront
Experiment has been described in detail in previous
reports(1,2) In the experiment, control over the propagation
of a virtual cathode at the front of an intense ...
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 ...
