✦ Synopsis

A small superconducting magnet coil, 16.39 cm outer diameter and 7.62 cm inner diameter, has been quenched to determine the rate of decayof current in the coil and to measure the temperatures in the coil induced by the quench. The measured current decay and the temperatures have been compared with the theoretical predictions obtained by using a control volume-finite difference numerical scheme developed by us. Two sets of experiments have been performed: the first set results in a two-dimensional quench proPagation, while the second one results in three-dimensional quench propagation through the coil. The results of the experiment agree closely with those of the predictions indicating that the techniques used for the experimental observations and numerical modelling are sound and are applicable to the study of large magnet coils as well.

The a.c. quench current level of a superconducting cable when formed into a coil is, in general, lower than that of a short sample. The current in the coil induces a selfmagnetic field on the superconducting winding. It was found from our experiments that the transition from the superconducting stat
