TL;DR: The Central Solenoid Model Coil (CSMC) was designed and built from 1993 to 1999 by an ITER collaboration between the U.S. and Japan, with contributions from the European Union and the Russian Federation.
Journal ArticleDOI
Fundamental Characteristics of Superconducting Fault Current Limiter Using LC Resonance Circuit
TL;DR: In this paper, a new type of fault current limiter (FCL) utilizing series LC resonance circuit composed of a superconducting coil and a capacitor is proposed, which suppress the rapid increase of a fault current by its energy storing capacity.
