Research and Development of a V-band 3.2 Millimeter Magnetron

Abstract

The report describes the work performed to develop an inverted coaxial V-band cavity-stabilized magnetron. The study included the development and cold testing of X- and V-band models of the anode, and the design and testing of critical components of the tube such as the heater cathode assembly and the mode damper. A 9-scaled X-band cold test model of the anode, cavity and output was made and extensively investigated. The fast cyclotron mode interference problem was explored. A satisfactory V-band anode was made with E.D.M. techniques. A good unloaded Q was measured with the V-band anode and a satisfactory match was obtained with a half wave ceramic window. A practical magnetic circuit was worked out to provide high magnetic field. An investigation of carburized ceramic dampers was made and, although a satisfactory damper was not developed during this period, the design of a good damper does not appear to be a difficult problem. A model of the heater cathode assembly was constructed for bell jar test and was life tested for a period of 1040 hours.
