MIPROWAVE EMISSION FROM PULSED, RELATIVISTIC e-BEAM DIODES II. THE MULTIRESONATOR MAGNETRON

نویسنده

  • G.
چکیده

The design and operating characteristics of relativistic, electron beam magnetrons are described. The magnetrons are comprised of a pulsed field-emission cathode (-360kV, ~15kA, -30nsec) and several coupled resonators embedded in the anode block. The tubes are designed to work at fixed frequency, in range from 2.3 to 5GHz. The peak powers generated are typically 500 to 1000MW. *This work was supported by the Air Force Office of Scientific Research (Grant AFOSR77-3143).

The experimental effect of encouraging transparent-cathode in relativistic magnetron with "ETIGO-IV"

The Magnetron is one of the efficiency high-power microwave source, although the energy conversion efficiency decreases with pulsed-power relativistic electron beam. We study the capability to increase energy conversion efficiency of Relativistic Magnetron by using Transparent Cathode. The Transparent-Cathode consists of independent cathode strips. Each cathode strip caused azimuthal magnetic f...

MOCVD growth and characterization of AlGaInN multiple quantum well heterostructures and laser diodes

We demonstrate room temperature, pulsed, current-injected operation of InGaAlN heterostructure laser diodes with mirrors fabricated by chemically assisted ion beam etching. The multiple quantum well devices were grown by organo–metallic vapor phase epitaxy on c-face sapphire substrates. The emission wavelengths of the gain-guided laser diodes were 400 nm. The lowest threshold current density ob...

The Target Material Influence on the Current Pulse during High Power Pulsed Magnetron Sputtering

The current-time characteristic during high power pulsed magnetron sputtering is measured under identical conditions for seventeen different target materials. Based on physical processes such as gas rarefaction, ion-induced electron emission, and electron impact ionization, two test parameters were derived that significantly correlate with specific features of the current-time characteristic: (...
