Abstract :
Next generation High Energy Physics (HEP) applications consider high magnetic fields (>12 T) at liquid helium temperatures as well as low magnetic fields (/spl sim/2 T) and temperatures above 30 K. Multifilament Bi-2223 conductors have achieved the performance to be considered for these applications. In the low temperature, high magnetic field situation, Bi-2223 offers unique advantages over Nb/sub 3/Sn. Issues of Jc, field quality, magnet stability, strain tolerance, and manufacturability are discussed for accessing the merits of Bi-2223 as compared to Bi-2212 and A-15 materials for HEP.
