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.}, title = {Stability test results on the aluminum stabilized superconductor for the helical coils of LHD}, volume = {Vol.9}, year = {1999} }
