Abstract

In situ strain measurement was made for Bi2223 superconducting filaments in Ag-sheathed Bi2223 composite tapes utilizing synchrotron radiation. The residual strain was 0.05 ± 0.01% in compression. A small deviation from linear relationship between strain of the Bi2223 filaments and the average strain of the sample was found, meaning a decrease in elastic modulus of the filament even below the irreversible strain.
