High power high brightness electron beam generation in a pulse-line driven pseudospark discharge
(IEEE, 1993-05-17)
High brightness (~3×1010 A/m2rad2 ), high power density (~1010 W/cm2) electron beams have been generated by the mating of a hollow-cathode discharge device operating in the pseudospark regime to the output of a high power ...
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 ...
High power, high brightness electron beam generation in a pulse-line driven pseudospark discharge
(IEEE Institute of Electrical and Electronics, 1993)
High brightness (m 3 x 10" A/m2rad2), high
power density (- 1O1O W/cm2) electron beams have
been generated by the mating of a hollow-cathode
discharge device operating in the pseudospark regime
to the output of a high ...
A Novel highly accurate synthetic technique for determination of the dispersive characteristics in periodic slow wave circuits
(IEEE, 1992-11)
A novel, highly accurate (0.1-0.5%) synthetic technique
for determining the complete dispersive characteristics
of electromagnetic modes in a spatially periodic structure is
presented. It was successfully applied for ...
Experiemental study of interaction of microwaves with a nonmagnetized pulsed-plasma column
(American Institute of Physics, 1992-09-01)
The time evolution of backscattered and sidescattered microwaves from a plane conductor
covered by a pulsed-plasma column has been studied; transmitted signals along the axial and
transverse directions of the column have ...
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 ...
Linear analysis of a finite length plasma-filled backward wave oscillator
(American Institute of Physics, 1992-04)
Absolute instability in a plasma-filled backward wave oscillator with sinusoidally corrugated
slow wave structure driven by an intense relativistic electron beam has been analyzed
numerically. The maximum spatial growth ...
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 ...
