A High-average power tapered FEL amplifier at submillimeter frequencies using sheet electron beams and short-period wigglers
A high-average-power FEL amplifier operating at submillimeter frequencies is under development at the University of Maryland. Program goals are to produce a CW, ~ 1 MW, FEL amplifier source at frequencies between 280 GHz ...
Near-millimeter free electron lasers with small period wigglers and sheet electron beams
Electron cyclotron resonance heating (ECRH) of plasmas in magnetic fusion research and space-borne radar systems are both projected to require high power radiation sources at wavelength λ not, vert, similar 1 mm. For ECRH, ...
Periodic magnetic focusing of sheet electron beams
(American Institute of Physics, 1994-05)
Sheet electron beams focused by periodically cusped magnetic (PCM ) fields are stable against low-frequency velocity-shear instabilities (such as the diocotron mode). This is in contrast to the more familiar unstable ...
Progress in high power millimeter-wave FELs with short period wigglers and sheet electron beams

A Short-period wiggler millimeter-wave free electron laser for plasma heating and space-borne radar
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 ...
High-average-power CW FELs for application to plasma heating designs and experiments
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 ...

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 ...
