Intense microwave pulses III

The goal of the Intense Microwave Pulses III conference was to present and critically assess new and innovative ideas, together with recent advances, in the generation and transmission of intense microwave pulses. Significant advances were reported on Super-Reltron source development. Also presented were numerous results of research on high-power klystron oscillators and amplifiers. Results of preliminary experimental studies were presented on an L-band Pasotron amplifier. Research was also reported on: vircators; the development of a family of frequency-agile relativistic magnetrons covering the bands from 1 to 3 GHz continuously; the status and challenges of powerful ultrawideband rf sources, including hydrogen spark gap pursers, hydrogen gas switches in combination with high-gain ultrawideband antennas; possible applications of high-power millimeter waves; development of simple, compact, efficient, and robust Hertzian EMP generators using oil spark switches that are capable of producing highly directive impulsive radiation fields with 100-ps rise times at gigawatt power levels; radiative instability theory; high-gain antenna design; antenna-induced parasitic current and backlobe reduction; high-power microwave sources based on photoconductive switching; analysis of ultrawideband pulses; generation of high-power microwave self-similar pulses from a free-electron laser, sheet-electron beam production and transport; theory of helical Cerenkov radiation; cyclotron resonance maser phenomenology; theory and experiments on mode locking in gyrotron oscillators; theory of wideband dielectric Cerenkov maser amplifiers; theory of plasma-filled backward-wave oscillators; high-repetition-rate tunable gyrotrons; field emission array cathodes for millimeter-wave gyrotrons; and high-power gyrotron development for electron cyclotron wave applications in magnetic confinement fusion
