Plasma wind tunnel for collisionless shock wave
Demonstration of efficiency enhancement in a high-power backward-wave oscillator by plasma injection
(American Physical Society, 1989-05-15)
An experimental demonstration of a strong enhancement of the interaction efficiency in a high-power relativistic backward-wave oscillator when plasma is injected is presented. Controlled plasma injection enhances the ...
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 ...
Intense relativistic electron beam propagation in evacuated drift tubes
(American Institute of Physics, 1984-06)
The propagation ofa magnetically confined intense relativistic electron beam (IREB) (I MeV, 27 kA, 20 ns FWHM) in vacuum drift tubes has been studied experimentally and theoretically. Experimental results for current ...
