15 MHz small-size magnetron for microwave heating
Small-sized packaged 3.4 kW CW magnetron is developed for 915 MHz microwave heating. Magnetron has double strapped 10 vane anode structure. For reduction of heat power the cathode is executed as thick molybdenum pipe with oxide covering. The 78 % efficiency and low noise level are achieved by improvement of uniformity of a magnetic field by optimization of iron poles. For joining with various power supplies anode voltage of the magnetron can vary in limits 4,2.5,2 кѴ by installation of magnets of a various magnetization degree. Magnetron is developed for work on a 196x30 mm waveguide. The magnetron design is patented as useful model. Magnetron can be used in scientific researches, medicine and commercial systems of microwave heating as an effective source of adjustable capacity with high quality of a spectrum.
