Scope
This document describes the method for measuring the critical bending diameter of Bi-2223 superconducting strips in the liquid nitrogen temperature range.
This document is applicable to Bi-2223 superconducting strip samples with a rectangular cross-section, silver/silver alloy cladding, and a critical current of less than 300 A (at 77 K, in a self-field, and with a voltage gradient of 1 μV/cm).
