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 ...
A High-average power tapered FEL amplifier at submillimeter frequencies using sheet electron beams and short-period wigglers
(Elsevier, 1990-09-17)
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 ...
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 ...
Free electron laser with small period wiggler and sheet electron beam: A Study of the feasibility of operation at 300 GHz with 1 MW CW output power
(1989)
The use of a small period wiggler (Cw < 1 cm) together with a sheet electron beam
has been proposed as a low cost source of power for electron cyclotron resonance heating
(ECRH) in magnetic fusion plasmas. Other potential ...
Near-millimeter free electron lasers with small period wigglers and sheet electron beams
(Elsevier, 1988-10)
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, ...
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 ...
