Studies of relativistic backward wave oscillators: Comparison bewteen theory and experiment
(SPIE, 1992)
Microwave sources based on backward-wave oscillators driven by 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 ...
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 ...
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 ...
Novel method for determining the elctromagnetic dispersion relation of periodic slow wave structures
(©1990 American Institute of Physics, 1990-09-24)
A novel method for calculating the dispersion relation of electromagnetic modes in an arbitrary periodic slow wave structure is reported. In this method it is sufficient to know the frequencies corresponding to three special ...

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 ...
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 ...
