Abstract

The thermo-electric stability of Cu/NbTi multifilament composite wires remains an important issue for magnet designers, especially, with respect to localized heat disturbances of short durations. Numerous attempts have been carried out to quantify the actual amount of energy needed to trigger a quench in superconductors. Various technologies are available to simulate quench precursors, but they are not fully satisfactory in terms of reproducibility and accuracy of the measurements. In the present paper, we report the results obtained with a novel heating method based on a fibered diode laser
