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 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.
