Abstract
A simply structured cavity resonator for a multi-cavity klystron which can position a movable tuning element at a location where the element should be located with respect to a widthwise direction of the element. The cavity resonator of the multi-cavity klystron includes a cavity envelope, and a movable tuning element slidable on upper and lower internal surfaces of the cavity envelope. Each of left and right internal surfaces of the cavity envelope have continuously formed first and second areas. A spacing between the first areas of the left and right internal surfaces of the cavity envelope is equal to a width of the movable tuning element, while a spacing between the second areas of the left and right internal surfaces of the cavity envelope is larger than the width of the movable tuning element. The second areas correspond go an available frequency band.
