Asymmetrical normal-zone propagation observed in the aluminum-stabilized superconductor for the LHD helical coils

Abstract

Transient normal-transitions have been observed in the superconducting helical coils of the Large Helical Device (LHD). Stability tests have been performed for an R&D coil as an upgrading program of LHD, and we observed asymmetrical propagation of an initiated normal-zone. In some conditions, a normal-zone propagates only in one direction along the… (More)
