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.
Claims7
A motor-driven device for preadjusted frequency tunings for a klystron, comprising a plurality of resonant cavities, each cavity being adjusted in frequency by means of a piston rigidly fixed to a rod whose position is controlled by a spring which bears on a plate, exerts its force on a cup which is rigidly fixed to the piston rod and locks said rod against the head of an adjusting screw wherein, irrespective of the frequency tuning chosen and in the case of each cavity, the distance between the plate and the head of the adjusting screw is constant, the locking position of the plate being movable according to the frequency which is chosen and the spring being compressed between the plate and the cup in a constant manner.
