被引用回数：1 パーセンタイル：52.78(Materials Science, Multidisciplinary)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
Sn, NbAl, 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.

The Engineering materials diffractometer, TAKUMI has finished its construction in Materials and Life Science Experimental Facility (MLF), Japan Proton Accelerator Research Complex (J-PARC) and began its operations from September 2008. TAKUMI is located at poisoned-decoupled-moderator beamline 19 in MLF and has two 90 degree detector banks which are installed with ENGIN-X type scintillator detectors. The best value of the resolution 
d/d is less than 0.2%. TAKUMI has a room temperature loading machine, a dilatometer (or 1273 K furnace) and a high temperature (up to 1273 K) loading device, and a low temperature (below 10 K) loading machine is developed during 2010 FY. We have con-ducted one instrumental group use which is to develop the residual stress analysis, two project uses including the optimization study of superconducting wires and the high pressure devices developments, and several general uses.
