We have developed a new probe for testing the influence of local contact load from crossing superconducting Nb3Sn strands. The probe is part of the TARSIS setup for strand stress–strain characterization. The results from the TARSIS setup with different probes developed for the characterization of axial tensile stress–strain, spatial periodic bending, contact from crossing strands and homogeneous transverse load enable discrimination in performance reduction per specific load type and per strand type.
