Abstract
Researches to study internal stress/strain behaviors in industrial superconducting composites have been started at TAKUMI of J-PARC, as soon as the completion of TAKUMI construction. Preliminary results obtained from strains measurements during tensile deformation of Nb3Sn strands and YBa2Cu3O7tapes, strains measurements during heating of Nb3Sn strands and residual strains measurements in a Nb3Sn Cable-In-Conduit Conductors are briefly described. The results can demonstrate possibilities of neutron engineering diffraction to solve problems in industrial superconducting composites by using J-PARC high flux neutron beam, even the volume fractions of superconducting phases in the composites are small and the superconducting phases locate inside the real components.
