| Popis: | 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 and wind' technique. The coils and magnets were characterized in the Hybrid III magnet and in a cryocooler at the FBNML, MIT. A 'wind and react' magnet generated a maximum self field of 2.6 T, at liquid helium (4.2 K), liquid neon (27 K) and liquid nitrogen (77 K) temperatures, respectively. A magnet generated over 1.0 T with a background field of 20 T at 4.2 K. A smaller magnet cooled to 20 K with a two-stage cryocooler has demonstrated 0.8 T in a 40 mm room temperature bore. > |
