Abstract
The unification of the reaction heat treatment cycle for Nb₃Sn strands produced by Europa Metalli (EM) and Vacuumschmelze (formerly: VAC, now: European Advanced Superconductors, EAS) is of great interest and importance for the intended construction of ITER. It will be shown that a unified heat treatment could be found for these two strand types, with the additional advantage of a total heat treatment time significantly shorter than recommended by the strand producers.
