Generation of High-Power Oscillations with a Magnetron in the Centimeter Band

Experiments are described for obtaining high-power oscillations from a four-cavity, water-cooled, demountable magnetron. Power outputs up to 300 watts at a wavelength of about 9 centimeters were measured. A sealed-off sample magnetron was built along similar lines and gave a power output of about 100 watts at the same wavelength under actual working conditions. An experimental magnetron was also built giving power output of two watts at a wavelength of about 2.6 centimeters.
