Summary

The rate of growth of normal zones has been calculated. Formulae are presented for the propagation velocity and for the normal zone voltage as a function of the hot spot temperature. In spite of very slow propagation (of the order of 1 cm/s), normal zone voltages seem adequate to allow the detection of normal zones before the conductor overheats. Finally, a formula for estimating the minimum quench energy is proposed. Estimates based on this formula indicate that potted magnets wound with silver-BSCCO conductors should not train.
