Abstract: Disclosed is a beam energy dispersion adjusting mechanism for superconducting proton cyclotron. The adjusting mechanism includes a vacuum cavity, bases are symmetrically mounted on outer walls of four faces of the vacuum cavity in horizontal and vertical directions, an electric cylinder and a transmission mechanism are mounted on each of the four bases, a jaws block and a position fixing plate are correspondingly provided on an inner wall of the vacuum cavity at each face. The transmission mechanism includes an oil-free sleeve, a moving connecting rod onto which the position fixing plate is fixed, a corrugated pipe, and an electric cylinder connecting block whose both ends are screwed with the moving connecting rod and the electric cylinder, the jaws block is fixedly connected with the position fixing plate. The disclosure utilizes the electric cylinder to drive the jaws block to complete specified linear displacement, and satisfies back-end beam quality requirements.
