Expected Performance of HTS-based Magnets
Expected performance of all Nb3Sn or all HTS magnets at 4.2 K for the same amount of superconductor:
Year 2000 data for Jc at 12 T, 4.2 K
Nb3Sn: 2200 A/mm2
BSCCO-2212: 2000 A/mm2
Near future assumptions for Jc at 12 T, 4.2 K
Nb3Sn: 3000 A/mm2 (DOE Goal)
BSCCO-2212: 4000 A/mm2 (2X from today)
Cu(Ag)/SC Ratio
BSCCO: 3:1 (all cases)
Nb3Sn: 1:1 or Jcu=1500 A/mm2
