Abstract

An industrial heating magnetron operating in L-band (915 MHz) and capable of producing 300 kW of continuous microwave power has been developed and is available for commercial sale. This high average power magnetron design, model CWM-300L is based on the presently-available CTL model CWM-75L, an L-band magnetron that produces 75 kW of continuous microwave power. The 300L magnetron operates at 32 kV and 10 A with a conversion efficiency exceeding 90% when freshly conditioned. To address specific problems, a paper-design version of the 300L is available although that new design has been neither fabricated nor tested.
