Cooling stability test of He II cooled LHD conductor (1) - current supply and measuring method

Abstract

This paper deals with experimental methods to perform the dynamic stability test of large-scale superconductors cooled by He II. The large helical device (LHD) conductor used in this work has a critical current of dozens of kA. It is difficult to supply such a large current to the conductor immersed in pressurized He II by use of an external power supply in… (More)
