In magnetic confinement fusion devices,plasma is confined and stabilized by strong magnetic fields generated by superconducting magnets.However,quench in superconducting materials remains a major threat to magnet safety.To develop more reliable superconducting materials and design safer magnet systems,an analysis of recent advances in the quench characteristics of superconducting materials and their experimental research was imperatived.This review summarized the current state of superconducting material technology,introduced the principles of quench characteristic measurement,compared the advantages and disadvantages of experimental setups under different cooling modes,and specifically focused on quasi-adiabatic apparatuses and quench propagation test methods for Cable-In-Conduit Conductors(CICC).Key research findings on quench behavior were summarized,while existing challenges were identified alongside practical recommendations.This review provides technical guidance for experimental research on quench characteristics of superconducting materials and conductors,and serves as a reference for the design of quench protection systems in superconducting magnets.
