Irradiation damage of A15-Nb3Si and Nb7Si

  • Ernst L. Haase

The behavior of the superconducting temperatureTc and the lattice parametera0 of polycrystalline Nb3Si and Nb7Si thin films as a function of 300-kV α-particle fluence was investigated. It was found that theTc depression of A15 Nb3Si is of the same size and nature as for other A15 materials. In contrast, the initialTc degradation of Nb7Si is a factor of three larger. The observed minimum in theTc vs fluence dependence of Nb3Si is discussed and a simple qualitative model is presented.
