Simulations of quench and recovery in CICC conductors

The authors discuss R. Wong´s (1989) CICC, a 1-1/2-D code that models thermal conduction through the insulation of an individual conduit. It is noted that, until recently, the calibration of CICC was restricted to measurements of helium expulsion in normal conductor. No actual quenches in ICCS (internally cooled cable-in-conduit superconductor) coils had been simulated. Recently, several experiments on ICCS conductors of different topology have been performed and compared with CICC simulations, with varying success. The authors report on the capability of CICC to predict and analyze ICCS recovery and quench, and on the code´s limitations and the need for further improvements
