First operation of a 94 GHz, sheet beam, FEL amplifier
(Elsevier, 2002-10-14)
Millimeter wave (94 GHz) amplification has been observed in the sheet beam, planar wiggler, free electron laser. Using a 4 A sheet beam (20 mm × 1.0 mm) at an electron energy of 530 keV, injected wave power of 5 W was ...
Plasma influence on the dispersion properties of finite-length, corrugated waveguides
(The American Physical Society, 1996-03)
We present an experimental study of the electromagnetic properties of transverse magnetic modes in a
corrugated-wall cavity filled with a radially inhomogeneous plasma. The shifts of the .resonant frequencies of
a ...
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 ...
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 ...
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 ...
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 ...
