Abstract :
The authors describe the results of an effort to develop a high-power, coaxial magnetron of unprecedented frequency agility capabilities and reliability. Specifically, the tube to be described-known as the VMX-1189B-operates over the 8.6-GHz to 9.6-GHz frequency range with a nominal output power of 250 kW. After a discussion of several high-reliability features which have been incorporated into the base magnetron itself, a detailed description of the Accusweep actuator is given, with attention to the many features which contribute to its superior performance and reliability. The characteristics of the VMX-1189B are also discussed.<>
