First operation of a 94 GHz, sheet beam, FEL amplifier
(Elsevier, 2002-10-14)
Millimeter wave (94 GHz) amplification has been observed in the sheet beam, planar wiggler, free electron laser. Using a 4 A sheet beam (20 mm × 1.0 mm) at an electron energy of 530 keV, injected wave power of 5 W was ...
Microwave generation in a high voltage triggered pseudospark discharge experiment
(American Institute of Physics, 1998-04-01)
A set of five experiments to study the microwave emission accompanying the high voltage pseudospark discharge are reported. The generation of the microwaves in all cases but one is attributed to electron beam-plasma ...
Intense charged particle beam propagation into vacuum
(SPIE, 1998-01)
The propagation of intense charged particle beams into vacuum without the aid of
externally applied confining magnetic fields is under investigation both theoretically and
experimentally. In the configuration under study ...
A High-voltage triggered pseudospark discharge experiment
(American Institute of Physics, 1996-11-01)
The design and execution of a pulsed high-voltage (350–400 keV) triggered pseudospark discharge
experiment is reported. Experimental studies were carried out to obtain an optimal design for stable
and reliable pseudospark ...

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 ...
Design of an efficient, low voltage, third harmonic, large-orbit gyrotron amplifier with a vane-resonator output cavity

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 ...
Plasma influence on the dispersion properties of finite-length, corrugated waveguides
(The American Physical Society, 1996-03)
We present an experimental study of the electromagnetic properties of transverse magnetic modes in a
corrugated-wall cavity filled with a radially inhomogeneous plasma. The shifts of the .resonant frequencies of
a ...
Electromagentic properties of corrugated and smooth waveguides filled with radially inhomogeneous plasma

Specific slow wave structures are needed in order
to produce coherent Cherenkov radiation in overmoded relativistic
generators. The electromagnetic characteristics of such
slow wave, resonant, finite length structures ...
Characterization of electron beams generated in a high-voltage pulse-line-driven pseudospark discharge
(American Institute of Physics, 1994-05-01)
Emittance and energy measurements have been performed on a high-brightness electron beam
(>1010Nm2 rad2
) with diameter in the range 1-3 mm and energy in the range 150-170 keY. This
electron beam is generated by the ...
