| Outline of Final Research Achievements |
To reveal the optimal strain state for high temperature superconducting composite, we developed cryogenic tensile testing system for synchrotron radiation experiment. Compact tensile testing apparatus is needed to mount on a goniometer in a synchrotron beam line. In this study, we adopted new cooling scheme in which tensile testing machine and GM cryo-cooler are installed in different cryostats and both of them are thermally connected with flexible link made of high purity aluminum. As a result of cooling test, the minimum temperature at a sample was confirmed t be 25 K. By using this system, we carried out a strain measurement with synchrotron diffraction technique in SPring-8. We succeeded to measure the residual strain and internal strain under axial applied tensile strain at temperatures between 30 K and room temperature.
