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 ...
Experimental and numerical studies of sheet electron beam propagation through a planar wiggler magnet
(IEEE, 1993-12)
Detailed experimental studies on sheet relativistic
electron beam propagation through a long planar wiggler are
reported and compared with numerical simulations. The planar
wiggler has 56 periods with a period of 9.6 ...
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 ...
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 ...
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 ...
Wiggler focused relativistic sheet beam propagation in a planar free-electron laser configuration
(Copyright 1989 American Institute of Physics. This article may be downloaded for personal use only. Any other use requires prior permission of the author and the American Institute of Physics., 1989-11-13)
The propagation of a relativistic sheet electron beam through a spatially periodic magnetic
field (wiggler) has been studied experimentally. The wiggler serves two purposes; it provides
beam focusing as well as the ...
Progress in high power millimeter-wave FELs with short period wigglers and sheet electron beams
(Institute of Electrical and Electronics Engineers, 1989-05)
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 ...
Short-period-wiggler free electron lasers with sheet electron beams
(Institute of Electrical and Electronics Engineers, 1988-06)
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 ...
