Radiation damage to BSCCO-2223 from 50 protons.

The use of HTS materials in high radiation environments requires that the superconducting properties remain constant up to a radiation high dose. BSCCO-2223 samples from two manufacturers were irradiated with 50 MeV protons at fluences of up to 5 x 10{sup 17} protons/cm{sup 2}. The samples lost approximately 75% of their pre-irradiation I{sub c}. This compares with Nb{sub 3}Sn, which loses about 50% at the same displacements per atom

BSCCO-2223 samples from two manufacturers were irradiated with 50 MeV protons at fluences of up to 5 x 1017 protons/cm2. The samples lost approximately 75 percent of their pre-irradiation Ic. This compares with Nb3Sn, which loses about 50 percent at the same displacements per atom
