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 ...
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 ...
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 ...
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 ...
