Research on Compact, High-Energy, Microwave Sources (MURI '94)
Abstract
The activity at the University of Maryland was primarily devoted to research of the following four topics: 1) frequency-multiplying gyrotron amplifiers; 2) relativistic backward wave oscillators; 3) plasma-filled microwave sources; 4) synthesis of advanced ceramics for microwave tubes. The present state of art has electron beams generated in ferroelectric guns operating at 500 kv and 300 A in 250 ns pulses. Current densities are typically less than or of order 100 A/cm2, although higher current densities have been recorded from localized regions.
