Hybrid Accelerated Focusing Superconducting Cavity

Abstract

The invention relates to a hybrid accelerating focusing super-conduction cavity. Four liquid helium cooling grooves are formed in a super-conduction resonant cavity cylinder and are in parallel to one another, two opposite liquid helium cooling grooves are communicated by a plurality of conical cylinders, a circular ring-shaped accelerating tube is arranged between two conical cylinders, the central lines of the plurality of accelerating tubes and the central line of the super-conduction resonant cylinders are in the same central line, four focusing box are arranged among the accelerating tubes, are perpendicular to one another and are symmetrically fixed on the liquid helium cooling grooves, the conical cylinders communicates with the liquid helium cooling grooves, and liquid helium in the conical cylinders communicates with liquid helium in the liquid helium cooling grooves. The hybrid accelerating focusing super-conduction cavity has the advantages that the hybrid accelerating focusing super-conduction cavity is in a super-conduction state when working in a low-temperature state, the resistance is small, and the high-frequency loss is small; the beam acceleration function and the beam focusing function are combined in the same high-frequency structure, the structure is compact, and the beam quality is excellent; and the length of an accelerator is effectively reduced, and the construction cost of the accelerator is reduced.
