Abstract :
This paper describes a model for calculation of magnetic instabilities in superconducting wires with transport current and reports results of instability simulations in Nb3Sn strands from different manufacturers. The effect of magnetic instabilities on the strand and cable performance is presented and a criterion for the maximum effective sub-element size of strands for high field magnets is formulated.
