Description
A low loss Nb3(SnIn) strand was developed for the poloidal coil developed by JAERI for a tokamak fusion device. The strand is composed of a single Nb3(SnIn) filament bundle island surrounded by a Ta barrier in a Cu matrix. The time constant of the coupling current between filaments was measured with a newly developed technique. The time constant was much higher at zero magnetic field and was around 0.5 microsecond in fields higher than 3 T. The constant also depended on the thickness of bronze between the Ta barrier and the filaments rather than the Ta thickness. Superconducting properties are graphed and a mathematical model is discussed
