Increasing Pulse Length and Repetition Rate of Relativistic Magnetrons and MILO

Abstract

The relativistic magnetron is the most compact and efficient high power microwave (HPM) source. The MILO (Magnetically Insulated Line Oscillator) is an HPM source that is more efficient from a systems standpoint - it does not require an external magnetic field. Two main ideas are being pursued in computation and experiments: 1) A relativistic magnetron with diffraction output (MDO) powered by a split cathode (we moved away from using a magnetic mirror to the split cathode as it offers tremendous advantages and is simpler). 2) The use of carbon nanotube cathode woven carpets in relativistic magnetrons and the MILO. This topic is an on-going collaboration with Dr. Steven Fairchild (AFRL/RX) who spent time at UNM for this collaboration and Drexel University and a spin-off company Dexmat. This final report presents the results of theory, particle-in-cell simulations, experiments, and plasma diagnostics that advanced our understanding of the MDO and MILO. It also summarizes our interactions with other performers, provides a management summary, and lists the journal articles resulting from the research.
