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 ...

experiment, positive ions are trapped in the potential
well at the head of ...
A High-power backward-wave oscillator driven by a relativistic electron beam
(IEEE - Transactions on plasma science, 1985-12)
A high-power backward-wave oscillator (BWO) has been constructed that is driven by a relativistic electron beam (REB). A typical electron beam of 2-4 kA is accelerated across a diode potential of 650-800 kV and then guided ...
High power microwave generation from a large orbit gyrotron*
(IEEE - Transactions on Nuclear Science, 1985-10)
A study of the production of high power microwave radiation from a large orbit gyrotron in azimuthally periodic boundary systems has been conducted. Linear growth rates have been calculated for the 2¿ modes of magnetron-like ...
