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 ...
Theoretical and experimental investigations of the cyclotron interaction effect on relativistic backward wave oscillator operation
(SPIE, 1993)
Microwave sources based on backward-wave oscillators (BWOs) driven by relativistic electron beams are capable of producing high power coherent radiation in the cm and mm wavelength region. When the axial magnetic field is ...
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 ...
