Up-grade of the CICC stability analysis taking into account a current imbalance between strands in multistage cables

The results of the CICC stability analysis carried out with newly developed computer code STABLOS taking into account the effect of current imbalance between strands and subcables of a 40-50 kA range Nb/sub 3/Sn conductor of the type used in the ITER Model Coils and Inserts are presented. The effects of the transverse interstrand resistance, Cu: non-Cu ratio in the strands and the cabling stage which the current imbalance is referred to are considered. The approach uses a previously developed code for the multichannel CICC thermohydraulical analysis.
