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 ...
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 ...

Near-millimeter free electron lasers with small period wigglers and sheet electron beams
(Elsevier, 1988-10)
Electron cyclotron resonance heating (ECRH) of plasmas in magnetic fusion research and space-borne radar systems are both projected to require high power radiation sources at wavelength λ not, vert, similar 1 mm. For ECRH, ...
Observation of a resonant enhancement of microwave radiation from a gas-filled backward wave oscillator
(American Institute of Physics, 1988-08-15)
High-power microwave radiation at 8 GHz from a gas-fined backward wave oscillator driven
by an intense relativistic electron beam has been measured. It has been observed that an order
of magnitude resonant increase in ...
