INVESTIGATIONS OF CURRENT-CARRYING CAPACITY AND QUENCH BEHAVIOR OF A COMPOSITE SUPERCONDUCTOR BY MAGNETIC-FLUX PUMPING METHOD

Results of current-carrying capacity measurements and the quench behav iour analysis for a single Cu/NbTi composite superconducting wire unde r adiabatic cooling conditions are presented. The data are received us ing as well the usual resistive method as the contactless flux pumping method. The results obtained show that the latter method may be used not only for current-carrying capacity measurements but also for cryos tability parameters determination. These results may be important for stability tests of high-current cables for large-scale applications (s uch as SMES, pulsed magnet systems etc.).
