Design and Testing of a Permanent Magnet for a Compact Relativistic Magnetron with Diffraction Output
Abstract
Abstract Total relativistic magnetron system efficiency, compactness, and mobility are enhanced by replacement of pulsed electromagnetics or DC cryomagnets with permanent magnets. Research in this area would assist in future Navy needs in high power RF. At the University of New Mexico (UNM) we would like to explore the possibility of implementing a permanent magnet for relativistic magnetron operation. Recently at UNM we performed the preliminary experimental demonstration of an extremely high efficiency Magnetron with Diffraction Output (MDO). Thus far, the MDO has shown a total microwave source efficiency of 63% experimentally and with further optimization of the experimental setup we are confident that we would be able to verify 73% efficiency, as predicted by the simulations. Here, we would like to propose the possibility of implementing a permanent magnet for MDO operation to increase the total system efficiency. The feasibility of the permanent magnet will first be tested on the standard A6 magnetron that uses a simple mode converter. This is because, in order to accommodate a permanent magnet on the high efficiency MDO, a brand new MDO will have to be constructed. Here we will design and test a permanent magnet for the compact MDO using a simple mode converter. Below is the order in which we plan to conduct the experiments: 1. Experimentally verify the concept of the simple mode converter 2. Test the performance of the permanent magnet on the compact A6 magnetron 3. Propose a permanent magnet design for the high efficiency MDO. The costing of this effort is described in Volume 2 of this proposal.
