✦ Synopsis

It is likely that a quench in the cable-in-conduit internally cooled superconductor (CCICS) is started by a quench of a single strand of the cable caused by strand motion. The disturbance due to strand motion is highly localized and of short duration. Therefore, to determine the stability of CCICS, we need to analyze the stability of the strand subject to the localized and short duration disturbance. For this stability analysis, we investigated the transient heat transfer from a single strand to supercritical helium (SHE) based on measured data. The paper presents a model to determine the transient heat transfer and also the results of stability analysis of CCICS.
