Problems solved by technology

However, using a heater to quench the entire superconducting magnet is sometimes unstable or the quench speed is still not fast enough, which often depends on factors such as the quality of the heater itself and the response time of the control heater circuit, for example, the quality is not good enough The heater may prolong the overall quench time, making the quench not timely enough

Abstract

The invention relates to a superconducting magnet system, which comprises a coil support structure, a plurality of superconducting coils and a plurality of conducting rings, wherein the superconducting coils are supported and fixed through the coil supporting structure, and the conducting rings have electric conducting and heat conducting performance and are internally embedded inside the coil support structure. Each conducting ring per se forms a short circuit connecting structure of a closed loop in the circumferential direction, and the conducting rings and the superconducting coils have the electromagnetic coupling setting.

Description

technical field [0001] The invention relates to a superconducting magnet system, in particular to a superconducting magnet system with a quench protection structure. Background technique [0002] With the vigorous development of superconducting technology and superconducting materials, superconducting magnets have broad application prospects. Due to the advantages of small size, high current density, low energy consumption, and high magnetic field strength, superconducting magnets are increasingly used in basic scientific research, medical and health, transportation, and national defense industries. For example, in a magnetic resonance imaging (Magnetic Resonance Imaging, MRI) system, a superconducting magnet is used to generate a uniform magnetic field. [0003] When the working superconducting magnet returns from the superconducting state to the resistive state, it is called Quench. This may be caused by a parameter such as temperature, the strength of the external magne...
