Specific slow wave structures are needed in order
to produce coherent Cherenkov radiation in overmoded relativistic
generators. The electromagnetic characteristics of such
slow wave, resonant, finite length structures ...
Experimental realization of millimeter-wave amplification by a sheet beam free electron laser
(American Institute of Physics, 1994-03-14)
We report an observation of millimeter-wave (94 GHz) amplification in a sheet beam, short period,
planar wiggler: free electron laser amplifier. The observed gain is about 5 dB for a 530 keV, 4 A
beam through a 54 cm ...
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 ...
Propagation of wiggler focused relativistic sheet electron beams
(American Institute of Physics, 1988-02-09)
A recent design concept for millimeter-wave free-electron lasers [J. Appl, Phys, 60, 521
( 1986)] would require the stable propagation of a sheet electron beam through a narrow
waveguide channel. Experimental results ...
Low-voltage, megawatt free-electron lasers at a frequency near 300 GHz
(SPIE, 1988-01)
Design procedures and beam transport feasibility experiments Il.re discussed for a novel,
millimeter-wave free electron laser (FEL) concept employing short period magnetic
undulators and a sheet electron beam. The ...
