High-energy neutron irradiation of superconducting compounds
The effect of high-energy neutron irradiation (E greater than 1 MeV) at ambient reactor temperatures on the superconducting properties of a variety of superconducting compounds is reported. The materials studied include the A-15 compounds Nb$sub 3$Sn, Nb$sub 3$Al, Nb$sub 3$Ga, Nb$sub 3$Ge and V$sub 3$Si, the C-15 Laves phase HfV$sub 2$, the ternary molybdenum sulfide Mo$sub 3$Pb$sub 0$$.$$sub 5$$S$$sub 4$ and the layered dichalcogenide NbSe$sub 2$. The superconducting transition temperature has been measured for all of the above materials for neutron fluences up to 5 x 10$sup 19$ n/cm$sup 2$. The critical current for multifilamentary Nb$sub 3$Sn has also been determined for fields up to 16 T and fluences between 3 x 10$sup 17$ n/cm$sup 2$ and 1.1 x 10$sup 19$ n/ cm$sup 2$. (auth)
