improvement of superconducting characteristics of a superconducting coil after it has been cycled in temperature or magnetic field and quenched several times Note 1 to entry: The operating characteristics, usually the current-carrying capacity of the superconducting wire, tend to improve toward short-sample characteristics. Note 2 to entry: Short sample characteristics: the current-carrying capacity of a superconducting wire as measured on a short sample usually less than several meters long in a background magnetic field transverse to the direction of current flow.
