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 ...
Measurements and simulation of controlled beamfront motion in the laser controlled collective accelerator
(Institute of Electrical and Electronics Engineers, 1989-03)
In the Laser Controlled Collective Accelerator, an intense
electron beam is injected at a current above the vacuum space
charge limit into an initially evacuated drift tube. A plasma
channel, produced by time-sequenced, ...
Short-pulse high-power microwave propagation in the atmosphere
(American Institute of Physics, 1988-02-12)
The propagation of high-power 00-200 kW/cm2
) short-burst (3-30 ns) microwave pulses in
the atmosphere has been studied experimentally. Microwave power from a large orbit gyrotron
operating at 9.6 GHz is focused by a ...
Propagation of wiggler focused relativistic sheet electron beams
(American Institute of Physics, 1988-02-09)
A recent design concept for millimeter-wave free-electron lasers [J. Appl, Phys, 60, 521
( 1986)] would require the stable propagation of a sheet electron beam through a narrow
waveguide channel. Experimental results ...
Low-voltage, megawatt free-electron lasers at a frequency near 300 GHz
(SPIE, 1988-01)
Design procedures and beam transport feasibility experiments Il.re discussed for a novel,
millimeter-wave free electron laser (FEL) concept employing short period magnetic
undulators and a sheet electron beam. The ...
Experimental study of propagation of intense relativistic electron beams in nonconducting vacuum drift tubes after passage through a localized plasma source
(American institute of physics - Journal of applied physics, 1987-04-01)
Presents a study which examined the propagation of intense relativistic electron beams into evacuated nonconducting drift tubes after passage through a localized plasma source. Details of the time-integrated photographs ...
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 ...
