Abstract
The transition of a superstabilized conductor to the normal resistive state is accompanied by a redistribution of current which, due to the size of the normal metal matrix, is long compared with the thermal propagation and greatly affects the propagation velocity. To simulate adiabatic propagation, a 2-m sample of ALEPH conductor, suspended in a vacuum and indirectly cooled at its extremities, was tested. Quenches were induced by heaters, and velocities were measured using voltage taps. Results are presented of tests at different currents and under different magnetic fields. These results are in good agreement with theoretical predictions.
