مستخلص: Abstract: The effect of 132Xe27+ion (167 MeV) irradiation at angles of 20°, 30°, 60°, and 90° to the tape surface is studied. The critical parameters of the second-generation superconducting tapes are explored. The tapes on the based of the GdBa2Cu3O7 – xcompound are produced by SuperOx. The critical current (Ic) at 77 K in self magnetic field and the critical temperature (Tc) are plotted as a functions of ion irradiation fluence at different irradiation angles. A minor (up to ~5%) increase in the critical current of high-temperature superconducting (HTSC) tapes is observed for all studied irradiation angles for fluences in a range from 3.4 × 108to 5 × 109ions/cm2. The radiation resistance of the superconductor to ion irradiation is determined as a function of the irradiation angle. The threshold irradiation fluence Φthis measured to determine the radiation resistance of the tape. This is the value at which the critical current approaches zero. The dependence of Φthon the irradiation angle α can be approximated by the formula \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$${{\Phi }_{{{\text{th}}}}} = {{\Phi }_{0}} + A\exp ({{ - \alpha } \mathord{\left/ {\vphantom {{ - \alpha } t}} \right. \kern-0em} t})$$\end{document}.
