Abstract

Summary form only given. The recirculating planar magnetron (RPM) [1, 2] is a crossed-field device that combines the advantages of high-efficiency recirculating devices with those of planar devices: both large-area cathode (high current) and anode (improved thermal management). Experiments using the RPM-12a, the first L-band prototype, have successfully produced high power microwave pulses 50-300 ns in length at approximately 1 GHz [3]. The device is driven using the Michigan Electron Long Beam Accelerator with Ceramic insulator (MELBA-C), which delivers a pulsed cathode bias of -300 kV for durations of 0.3-1.0 μs, and a Helmholtz electromagnet capable of producing 0.15-0.2 T axial magnetic field.
