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 ...
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 ...
Experimental and numerical results on a millimeter-wave free electron laser amplifier
(Elsveier - Nuclear instruments and methods in physics research, 1993-07)
Progress in studies of a millimeter-wave free electron laser amplifier based on a small period planar wiggler and a sheet electron beam is reported. Successful propagation of a 15 A sheet electron beam has been accomplished ...
From linearity towards chaos: Basic studies of relativistic backward-wave oscillators
(American Physical Society, 1992-09-14)
Recent experimental studies have revealed for the first time some basic features of pulsed. relativistic (300-600 keY) backward-wave oscillators such as starting current, axial mode locking, and multifrequency
operation. ...
Relativistic plasma microwave electronics: Studies of high-power plasma-filled backward-wave oscillators
(American Institute of Physics, 1992-07)
The area of relativistic plasma microwave electronics has only recently generated renewed
interest. New experimental data are presented demonstrating that the presence of a
low-density background plasma in a relativistic ...
Studies of relativistic backward wave oscillators: Comparison bewteen theory and experiment
(SPIE, 1992)
Microwave sources based on backward-wave oscillators driven by relativistic electron beams are capable
of producing high power coherent radiation in the cm and mm wavelength regime. Although there have
been a number of ...
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 ...
Relativistic backward wave oscillators: Theory and experiment
(IEEE, 1991)
Microwave sources based on backward-wave oscillators
with relativistic electron beams are capable of producing
high power coherent radiation in the cm and mm wavelength
regime. Although there have been a number of ...
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 ...
