In situ interstrand resistance measurements were conducted on selected section of the inner coil of a full size (15 m) and a short (1 m) model SSC magnets. A model for evaluating single contacts resistance between two strands was developed. Using this model analyses of adjacent and non-adjacent strand contacts were performed. The interstrand resistance distribution throughout the coil was found to correlate with the quench location data as well as with the multipoles decay characteristics of the magnet. An anisotropic continuum based model for evaluation of cable eddy current losses was developed and results were compared with the experimental data
