โœฆ Synopsis

Thermal stability of a conduction-cooled Bi-2223/Ag pancake coil has been investigated by means of a time dependent numerical analysis. The coil is cooled by a cryocooler through a cooling plate. This study focused on the temperature profile in the coil and the thermal runaway current. It is suggested from the present analysis that not only enlarging the attached area of the cooling plate to the coil but also dispersing the cooling plate is an effective way to improve the thermal stability of a conduction-cooled HTS coil.

A theoretical optimization is performed for the conduction-cooling method of high Tc superconductor (HTS) current leads, which can be applied to the superconducting systems cooled directly by cryogenic refrigerators without liquid helium. The current lead is a series combination of a normal metal co
