Microwave generation from rotating electron beams in magnetron-type waveguides
(American Institute of Physics, 1983-07)
The production of high power microwave radiation at high harmonics of the electron cyclotron frequency by the interaction of a rotating electron beam with a magnetron-type conducting boundary has been studied theoretically ...
Collective acceleration of laser produced ions
(Institute of Electrical and Electronics Engineers, 1983-08)
Experimental studies of the collective acceleration of laser produced ions have been conducted. An intense relativistic electron beam (1 MeV, 30 kA, 30 ns) is emitted from a 4 mm diameter tungsten cathode and passes ...
Collective acceleration of light and heavy ions
(Institute of Electrical and Electronics Engineers, 1981-06)
The collective acceleration of ions (H, D, He, C, N, Ne, Al, Ar, Fe, Cu, Xe) from a well localized plasma immediately downstream of a relativistic electron beam diode is experimentally investigated. The ions are produced ...

Detailed experimental studies of a collective acceleration experiment in which a time sequenced laser-generated ionization channel is used to control the propagation of an intense relativistic electron bearnfront are ...
Shielded-source, short-pulse microwave propagation experiments
(Copyright 1989 American Institute of Physics. This article may be downloaded for personal use only. Any other use requires prior permission of the author and the American Institute of Physics., 1989-08-01)
The propagation of short-pulse, high-power microwaves through a neutral gas has been studied and breakdown limits determined in an experimental configuration in which the neutral gas test cell was carefully shielded from ...
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 ...
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 ...

Wiggler focused relativistic sheet beam propagation in a planar free-electron laser configuration
(Copyright 1989 American Institute of Physics. This article may be downloaded for personal use only. Any other use requires prior permission of the author and the American Institute of Physics., 1989-11-13)
The propagation of a relativistic sheet electron beam through a spatially periodic magnetic field (wiggler) has been studied experimentally. The wiggler serves two purposes; it provides beam focusing as well as the ...
Collective ion acceleration via laser controlled ionization channel
(Institute of Electrical and Electronics Engineers, 1987)
Initial results from a successful laser-controlled collective ion acceleration experiment at the University of Maryland are presented. In the experiment, positive ions are trapped in the potential well at the head of ...
