FREQUENCY TUNING DEVICE OF CRYOGENIC VESSEL FOR SUPERCONDUCTING ACCELERATION TUBE

摘要

A frequency tuning device of a cryogenic vessel for a superconducting acceleration tube is disclosed. The device comprises: a pair of pushers positioned at the upper parts of two half tube-shaped side members of the superconducting acceleration tube so as to receive external pressure; a pair of male and female sliding hinges respectively coupled to each one end of the pair of pushers so as to equally distribute the external pressure to both sides of the pair of pushers while sliding by receiving the applied external pressure; a power screw coupled to the pair of male and female sliding hinges by passing through the same, and increasing force applied to the center portions of the pair of pushers by a pitch angle; and a hinge joint coupled to the other ends of the pair of pushers so as to adjust the external pressure such that the external pressure is equally distributed to both sides thereof, wherein the pair of pushers function as a push lever by using the hinge joint as a center axis of movement.
