Paper Abstract

High power microwave (11PM) experiments with Aurora reflex diodes (ARDs) are analyzed. In particular the multi-wave guide logistics 11PM peak envelope power (PEP) and waveform consistency problems associated with multi-guide radial extraction are reviewed. A novel design involving an outer coaxial cavity to extract power from the ARD cavity via 2535 appropriately placed ports or an equivalently loaded peripheral opening (sideshoot aperture) is described. Tmproved extraction mode selection phase locking frequency stabilization and waveform smoothing via this coaxial ARD (or CARD) is predicted. Staged physics studies and scaling experiments to validate the 11PM operation of a full-scale CARD on a Pocobeam and Aurora are recommended. 1.
