Predictive quench initiation analysis of the ITER TF model coil

摘要

In the ITER TF Model Coil, the experimental evaluation of the superconducting critical properties will only be possible by heating the helium upstream of the inner joint. The goal of this predictive heat slug propagation and quench initiation analysis is to assess if a quench will be initiated in the high field region of the conductor or in the joint. An instability of the cryogenic system occurs when only one pancake is heated. To avoid the unwanted quench in the joint the test must be performed with high helium mass flow rates and slow heating procedures.
