Abstract
MgB2 is a hexagonal superconducting material, and its simple composition has led to the development of low-cost practical wires. However, the problem is that the strain characteristics of filaments are inferior to those of other practical wires, but there have been no strain measurements using diffraction method. The reason for this is presumably that it is a little too thick for synchrotron radiation measurements, and the large absorption cross section of the included boron-10 makes it difficult to obtain elastic scattering for neutron measurements. We prepared a wire substituted with boron-11, an isotope with small neutron absorption cross section, and attempted to measure its strain under tensile loading using pulsed neutron.
