Abstract
About 450 km of high JC Nb3Sn wires have been procured for the construction of two series-connected hybrid magnets by the National High Magnetic Field Laboratory (NHMFL). In addition to the quality assurance tests by the wire manufacturer, a receiving quality assurance inspection with a predetermined sampling frequency is carried out at the NHMFL. These tests include wire diameter, twist pitch, Cu/non-Cu ratio, IC, residual resistance ratio, hysteresis loss, and IC strain dependence. In this paper, the test procedures are described and the test results are presented. Based on these test results, all the wires have been accepted.
