Variable Power, Short Microwave Pulses Generation using a CW Magnetron

A Fundamental Study on Spectral Purity of a CW Magnetron for Microwave Power Transmission

The objective of the present study is to investigate spectral purity of a CW magnetron for a microwave power transmission system of Solar Power Satellites, or other radio applications. Oscillation spectra of a 2.45GHz oven magnetron were measured and the purity of the spectra is discussed. A filament-off magnetron has narrow bandwidth. In some conditions, however, the oscillation spectrum has F...

High-Power Microwave Generation Using A Ferroelectric Cathode Electron Gun

A two-stage 500 kV 200-A ferroelectric electron gun has been designed, fabricated, tested, and used in a high power microwave amplifier experiment. We report on the operational characteristics of the gun including measurements of the beam dynamics. The optimum conditions for application of the trigger and its timing are also reported. Faraday cup measurement shows that the beam radius is 4.1 mm...

Photoconductive generation of short electrical pulses of variable duration using a coplanar waveguide with capacitively coupled ground termination

Generation of High Peak and High Average Power Subnanosecond-Width 10-GHz Microwave Pulses

Excitation of 10-GHz gigawatt-range radiation pulses ~ 1 ns long in relativistic backward-wave oscillators with an elongated periodic slow-wave system has been studied. Accelerators based on a compact pulsed-periodic high-voltage generator type SINUS-160 and a generator employing an inductive energy storage, a semiconductor opening switch and a peaking hydrogen-filled spark gap have been develo...
