Enhancement of overall efficiency in large-orbit gyrotrons
(Taylor and Francis, 1990)
Energy recovery from the spent beam in gyrotrons can enhance their overall
efficiency. A technique for converting the rotational motion in the spent beam of
a large-orbit gyrotron into axial motion, before leading it ...
High-average-power CW FELs for application to plasma heating designs and experiments
(IEEE, 1990)
A short-period-wiggler (period - 1 cm), sheet-beam FEL has been proposed as a low-cost source of high-average-power (1 MW)
millimeter-wave radiation for plasma heating and space-based radar applications. Recent calculations ...

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 ...
Experimental studies of the laser controlled collective ion accelerator
(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., 1989-10-01)
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 ...
Numerical simulation of collective ion acceleration in the laser controlled collective accelerator
(Institute of Electrical and Electronics Engineers, 1989-05)
Progress in high power millimeter-wave FELs with short period wigglers and sheet electron beams
(Institute of Electrical and Electronics Engineers, 1989-05)
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, ...
