Abstract:

Process systems utilizing high Q cavities can be subject to difficulty in tuning, resulting in reduced operational stability and power coupling. The relationships between magnetron operation and cavity Q are discussed, as well as the effects of insufficient magnetron isolation, varying magnetron output frequency and the phenomenon known as the long lines effect. Techniques to improve system performance are also discussed, including those for increased isolation, constant frequency operation and variable Q.
