Abstract :
Investigations of quenching currents, stability and ac losses for two kinds of NbTi multifilamentary cable with very fine filaments are presented. Both of them comprise six strands of 0.1 mm diameter with many filaments of 0.5 μm dia. and a stainless steel strand of 0.1 mm diameter for reinforcement. These cables are epoxy-impregnated for practical windings. Even these designs result in good stability and low ac losses. If these cables are used in ac magnets, generating a maximum field of ac around 1.0 T, economical benefits are expected at power frequencies, 50 Hz/60 Hz.
