✦ Synopsis

Superconducting magnets operating in a pulsed field mode are exposed to magnetomechanical, thermomechanical and purely mechanical stresses. Since most materials incorporated in the magnet, such as the composite conductor, the insulation, the impregnants and the reinforcements, are strained to the limit of their yield strength, the mechanical and electrical behaviour of these materials will change during the first period of operation, until equilibrium conditions are reached.

In this paper a new model for Jc (B) is presented. Based on this model hysteretic losses are calculated and compared to measured data. Losses due to stress-induced pseudo-elastic effects of the composite are calculated.

The minimum energy required to quench a fully impregnated superconducting winding has been measured at a constant field of 5 T for various currents. Great care has been taken to match the experimental conditions with those presumed in the minimum propagating zone (MPZ) treatments of the situation. I
