Results of the Testing of ITER CC HTS Current Lead Prototypes

According to the procurement agreement with the International Thermonuclear Experimental Reactor project, the Institute of Plasma Physics, Chinese Academy of Sciences (ASIPP) in China is responsible for the construction and performance testing of 31 sets of feeder systems, which contain also 60 high-temperature superconducting (HTS) current leads. In 2014/2015, three pairs of prototype current leads of three different types are being built and tested. A first pair of correction coil (CC) type, 10-kA current lead prototypes was built and cold tested in ASIPP in early 2015. The test items cover the joint resistance, overheating time test, mass flow consumption in steady-state operation for various currents, and the pulsed current scenario test. This paper presents the test results for the prototype CC 10-kA HTS current leads.
