Superconducting cables have now become a mature technology used for energy transport, high-field magnets (medicine (MRI), high-energy physics (LHC)) and fusion applications (ToreSupra, eventually ITER and DEMO). The most performant superconductors being extremely brittle and strain-sensitive, their electrical performance can be strongly affected by their mechanical behavior. This degradation can be diminished by optimizing the geometry of cables using simulation tools. To validate them, the simulated cable geometry can be compared to the geometry of real cables, extracted from tomography images. This paper describes the analysis of the geometry from these images for three types of cables. To our best knowledge, this is the first paper providing both methods and results for the geometry analysis of superconducting cables. The results exhibit a good accuracy w.r.t. ground truths and the proposed features appear to be relevant for detecting deformations. Moreover, correlations can be established between some kinds of deformations.
