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 ...

High power RF amplifiers for accelerator applications: The Large orbit Gyrotron and the high current, space charge enhanced relativistic klystron
Los Alamos is investigating a number of high power microwave (RPM) sources for their potential to power advanced accelerators. Included in this investigation are the large orbit gyrotron amplifier• and oscillator (LOG) ...
Studies of relativistic backward wave oscillators: Comparison bewteen theory and experiment
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
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 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 ...
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 ...
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 ...
Design of a low-voltage, axially modulated, cusp-injected, third harmonic, x-band gyrotron amplifier experiment
(Institute of Electrical and Electronics Engineers, 1997-11)
We present the design of a prebunched, third harmonic small-orbit gyrotron experiment that utilizes a 45 kV, 8 A beam to produce over 185 kW of amplified power at 9.9 GHz in a 1.23 kG magnetic field. We detail the design ...
