The construction of the engineering materials diffractometer TAKUMI at J-PARC has been finished at the end of March 2009, and user programs have been started since January 2009. We proposed a project research with the title of "Stress/strain effects on industrial superconducting composites", and have carried out several preliminary experiments at TAKUMI. This project research aims to clarify internal strains behaviors in industrial superconducting materials generated due to their processes and/or during uses, and to understand the relation between the internal strains and their superconducting properties. Our interests are in developments of superconducting (Nb$$_3$$Sn, Nb$$_3$$Al, etc.) strands and HTC tapes, and in developments of superconducting (ITER and LHC) cables (composing many superconducting strands or tapes and other stabilizing and/or strengthening materials). In this opportunity, we will report our project research status more details.

Phase strains are always generated in the superconducting composites, due to differences on thermal expansion and deformability among the constituent phases. In contrast, internal strain state has high influences on superconducting properties, e.g. the presence of internal strain degrades critical current densities. Therefore, clarifying internal strains behaviors accurately will help us to develop superconducting composites having optimum superconducting performances during uses. However, the internal strains in superconducting composites have not been measured so far because of the composites configurations. Neutrons that have high penetration ability into metals may be a powerful tool to measure internal strains in the superconducting composites by the diffraction technique. Here, we introduce internal strain measurement techniques, our engineering materials diffractometer at J-PARC facility and our trials on measuring internal strains in several kinds of superconducting composites.
