“…While testing superconducting strands is very important for large superconducting magnet projects in general [2][3][4][5], it is particularly crucial for ITER Nb3Sn strands, which are supplied by multiple strand manufacturers. Therefore a verification test program is implemented involving a number of labs worldwide [6][7][8][9][10][11][12][13][14][15][16][17].…”

ITER Nb3Sn strand quality verification tests require large quantities of precise measurements. Therefore regular cross-checking between testing laboratories is critically important. In this paper, we present results from a cross-checking test of 140 samples between the National High Magnetic Field Laboratory, USA and the University of Twente, the Netherlands. The tests comprise measurements at 4.2 K on critical current, RRR and hysteresis loss, while at room temperature the chromium layer thickness, Cu/nonCu ratio, filament twist pitch, and diameter were determined. Our results show very good agreement between the two labs. The reasons for small random discrepancies are discussed.
