已进行了稳定性测试的铝/铜稳定的复合型超导体的短样品开发和用于池冷却的螺旋线圈的大型螺旋装置。由电阻加热器引发的纵向电压的波形在达到最终值之前显示出短时间的上升，这似乎对应于传输电流到纯铝稳定剂中的扩散过程。即使对于低于恢复电流的传输电流，传播速度也具有有限值，并且传播速度根据关于传输电流的方向而不同。
Stability tests have been carried out on short samples of the aluminum/copper stabilized composite-type superconductors developed and used for the pool-cooled helical coils of the Large Helical Device. The waveform of the longitudinal voltage initiated by resistive heaters shows a short-time rise before reaching a final value, which seems to correspond to the diffusion process of transport current into the pure aluminum stabilizer. The propagation velocity has a finite value even for the transport current being lower than the recovery current, and it differs depending on the direction with respect to the transport current.
