Abstract : The primary purpose of this conference was to present and critically assess current research on the generation and transmission of intense microwave pulses. The phenomenon of pulse shortening in high-power microwave sources received special attention. Effects were calculated for asymmetric loading of a magnetron cavity on the resonant frequency and quality factor of various cavity modes. Numerical simulations of magnetron phase locking were also presented. In gyrotron research, experiments on long-pulse microwave production by a high-power gyrotron with rectangular cross section were reported. Also presented was work on harmonic multiplication as a possible way to produce high frequency, large bandwidth, and high power in gyrotron oscillators and amplifiers. Also presented were experimental results on a novel design for a cyclotron maser having a periodic waveguide consisting of a two dimensional linear array of metal posts. In addition, research on unwanted-mode suppression in a gyrotron-backward wave oscillator was presented.
