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 ...
Beam conditioning for electron energy recovery systems in devices employing axis-encircling beams
(Taylor & Francis, 1988)
Depressed collectors are extensively used in linear-beam devices. In spiraling
beam devices, the motion of the spent beam needs to be converted into axial
motion before it can deliver energy to the retarding axial ...
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 ...
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 ...
Depressed collectors for a large orbit gyrotron
(1987-12)
An auxiliary magnetic cusp transforms
rotational motion in the spent beam of a Large-Orbit
Gyrotron into axial motion. Results
regarding the interfacing of this cusp with a
depressed collector region and the effects ...
A Short-period wiggler millimeter-wave free electron laser for plasma heating and space-borne radar
(1987-12)
We will report on the status of a new mm-wave
FEL research program based on short-period
electromagnet wigglers and a low voltage (500 kV)
sheet electron beam. Recent results of
measurements and theoretical modeling ...
Efficiency enhancement by using depressed collector techniques in devices employing gyrating electron beams
(Institute of Electrical and Electronics Engineers, 1987-06)
Design of a short-period-wiggler free electron laser experiment
(Institute of Electrical and Electronics Engineers, 1987-06)
