AbolishedSuperconductivity: Residual resistance ratio measurement of Nb-Ti composite superconductors
超导电性：铌-酞复合超导体剩余电阻比测定
Application Summary AI generated
This standard specifies the method for measuring the residual resistance ratio (RRR) of Nb-Ti composite superconductors, which is a key indicator of conductor purity and performance. It is applied in the quality control and testing of superconducting wires used in high-field magnets, such as those in MRI machines, particle accelerators, and fusion reactors. The measurement ensures the conductor meets the required electrical and thermal stability criteria for cryogenic applications.
