To study the effects of low-temperature irradiation on technological type II-superconductors, NbTi and V/sub 3/Ga multifilamentary composite wires, the critical current I/sub c/ and transition temperature T/sub c/ were measured before and after irradiation with 50-MeV deuterons at 10 and 15/sup 0/K, respectively. While the irradiation effects on I/sub c/ and T/sub c/ of NbTi are substantially unaffected, the V/sub 3/Ga wires undergo a reduction in I/sub c/ of about 50 percent and T/sub c/ decreases from 14.7 +- 0.1/sup 0/K to 12.3 +- 0.1/sup 0/K at a total deuteron flux of 2.6 x 10/sup 17/ cm/sup -2/. Annealing experiments at room temperature and 100/sup 0/C show only a small recovery of the superconducting properties up to 15 percent. The field dependence of the volume pinning force densities P/sub V/ was determined and the results are shown to be consistent with a qualitative dynamic pinning model. (auth)
