The influence of the ion irradiation 132 Xe 27+ (167 MeV), 86 Kr 17+ (107 MeV), and 40 Ar 8+ (48 MeV) on critical properties ( I c , T c , Δ T c ) of superconductor tapes of the 2‐nd generation GdBa 2 Cu 3 O 7− x (SuperOx) are studied. It is shown that the critical current slightly increases and the width of the transition to the superconducting state reduces at low doses of Xe‐irradiation. The obtained results enable the authors to estimate the radiation resistance of this HTS‐2G tape to the used irradiation. As for the critical temperature, its decrease begins at considerably higher fluences than the decrease in the critical current, and Δ T c also changes. The decrease in the critical current can be explained by the irradiation‐induced disorder of coherent boundaries between crystallites. At the instant of T c to zero, it is possible to roughly estimate the track radii induced by the ions.
