Critical currents are reported for several Ag/BSCCO single-pancake coils in static magnetic fields ranging from 0 to 5 T and temperatures from 4.2 K to 105 K. The sample cells were co-wound of one to six tape conductors in parallel. Since the closed

The powder-in-tube approach was successfully used to fabricate silver clad Bi-2223 in >100 m lengths of mono and >800 m lengths of multifilament tape. The tapes were wound into pancake and layer coils using the 'wind and react' as well as the 'react

We report results on the critical current density J/sub c/(T,H) at various fields and temperatures of Bi-2223/Ag tapes and small coils. In field measurements on small coils were performed under ascending and descending fields to investigate hystereti

After fabricating long lengths (30–100 m) of Ag-clad Bi-2223 tapes by the powder-in-tube process, we co-wound them into pancake-shaped coils by the “wind-and-react” approach. Test magnets were then fabricated by stacking and connecting the coil

Significant progress has been made in the development of high-critical-temperature (high-Tc) mono- and multifilament bismuth-based superconductors by the powder-in-tube (PIT) technique. High critical current density (Jc) has been achieved in both sho
