A “react-and-jacket” processed Nb3Sn conductor consisting of a Rutherford cable and aluminum-alloy jacket has been developed for fusion magnets. This study investigates the effect of bending on the critical current and the n-value of this conductor, which has a cross-section of 17 × 4.9 mm2. The conductor was wound in a three-turn coil and its critical current was measured in a superconducting magnet. The degradation of the critical current and the n-value due to the bending strain were assessed using an empirical formula for the strain dependence.
