Abstract : A mechanism of induced presistent currents is offered to explain the low current carrying capacity of Nb-Zr solenoids. The persistent currents are induced as the magnet is energized and are of sufficient magnitude to saturate the superconducting filaments. The magnitude of the induced currents can be estimated from a measurement of the residual field in the solenoid. The current carrying capacity of Nb-Zr solenoids is shown to be a particular function of field, inside diameter, and geometry. The most important conclusion drawn is that to generate fields in large bore magnets will require considerable more wire than would be predicted from considerations neglecting the induced currents.
