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 ...

We present the theoretical design of a secondharmonic
small-orbit gyrotron amplifier which utilizes the interaction
between a 35-kV 4-A beam and a TEoll cavity to produce
over 70 kW of amplified power at 9.9 GHz in a ...
A Novel highly accurate synthetic technique for determination of the dispersive characteristics in periodic slow wave circuits
(IEEE, 1992-11)
A novel, highly accurate (0.1-0.5%) synthetic technique
for determining the complete dispersive characteristics
of electromagnetic modes in a spatially periodic structure is
presented. It was successfully applied for ...
A Short-period wiggler millimeter-wave free electron laser for plasma heating and space-borne radar
(1987-12)
We will report on the status of a new mm-wave
FEL research program based on short-period
electromagnet wigglers and a low voltage (500 kV)
sheet electron beam. Recent results of
measurements and theoretical modeling ...
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 ...
A High-average power tapered FEL amplifier at submillimeter frequencies using sheet electron beams and short-period wigglers
(Elsevier, 1990-09-17)
A high-average-power FEL amplifier operating at submillimeter frequencies is under development
at the University of Maryland. Program goals are to produce a CW, ~ 1 MW,
FEL amplifier source at frequencies between 280 GHz ...
Short-period-wiggler free electron lasers with sheet electron beams
(Institute of Electrical and Electronics Engineers, 1988-06)
Experimental studies of overmoded relativistic backward-wave oscillators
(Institute of Electrical and Electronics Engineers, 1998-06)
Internal field-emission breakdown in the electrodynamic
structures of high-power microwave (HPM) devices can
seriously limit the device’s output power and pulse duration.
Increasing the diameter of the electrodynamic ...

We present the design of a 100 kW, J-band, third
harmonic large-orbit gyrotron amplifier which utilizes the interaction
between a 45 kV, 4 A beam and a vane resonator
output cavity operating in the “?r”-mode. An efficiency ...
