The application belongs to the technical field of superconducting materials, and particularly relates to a superconducting composite wire and a preparation method thereof. The application provides a superconducting composite wire, which comprises, from inside to outside, an inner tin method Nb3Sn sub-element, a thermal sensitive phase change barrier layer, a Cu-Mn-Ni high-damping copper alloy stabilizing layer, a thermochromic warning coating and an outer insulating sheath. The application can be widely applied to high-field magnets in fusion reactors, high-energy accelerators and advanced MRI systems, and can significantly improve the operation safety and state monitoring capability.

The application discloses a tuning method for a four-cavity high-energy accelerator, and comprises the following steps: arranging a tuning motor and an electronic ruler on the outer part of each cavity of the four-cavity resonant cavity, setting the initial positions of the four tuning motors and the initial positions of the electronic rulers respectively equipped on the four tuning motors; moving the tuning motor M1, and using the tuning motor M1 to complete the searching of the resonant point in the S1 state of the low-level control system, the amplitude climbing in the S2 state, and the amplitude stable closed loop in the S3 state; when reaching the thermal balance, entering the voltage deviation compensation stage: taking the capacitance variation as a step, alternately adjusting the capacitance variations of the tuning motors M1, M2, M3 and M4, so that the voltage deviations among the tuning motors M1, M2, M3 and M4 are close to 0; the method of "step" + "electronic ruler" + "contrast table" + "fitting curve" + "alternately adjusting" is adopted, and the problem of deviation compensation confusion caused by signal delay and mechanical transmission error during multi-motor tuning is solved.
