ABSTRACT:
A klystron comprises a plurality of resonant cavities, the frequency of which is defined by a piston within each cavity. In order to change the frequency of the klystron, each piston is provided with a rod applied against an adjusting screw under the pressure of a spring. In order to reduce the bulk of the springs, the distance between a screw head and the plate on which the springs are applied remains constant irrespective of the length of the adjusting screws. This is obtained by means of a set of switches which are fixed on the movable plate and control the compression of the springs by checking the position of a cup in which each spring exerts its force on the corresponding piston rod.
