Abstract
A band selector for a klystron includes a cam carrier and a plurality of cam followers. The cam carrier includes a plurality of cams with the cams being arranged in a plurality of rows. Each of the cam followers has a first end adapted to be mounted to a respective one of the plungers in the klystron and a second end. The cam carrier is positionable so that a selected one of the rows aligns with the cam followers. The cam followers are normally biased so that the second end of the cam followers abuts a respective one of the cams. The band selector further includes a first member movable between a first position and a second position. When the first member is in the first position, it is non-interactive with the cam followers. When the first member is moved to its second position, it becomes engageable with the first end of each of the cam followers to remove the second end of the cam followers from abutment with the respective one of the cams. Thus, the first member when moved to the second position allows the cam carrier to be repositioned so that another row of cams may be utilized for a different band. Finally, the band selector of the present invention includes a pneumatic actuator engageable with the first member to move the first member from the first position to the second position. When the pneumatic actuator is disengaged from the first member, the cam followers under their biasing return the first member to the first position.
