For the first time, experiments have been carried out on the effect of low fluences (~2.7·1014 cm-2) of mixed ion irradiation on the superconducting characteristics of an NbN film. The critical transition currents (obtained from static current-voltage characteristics) and the R(T) dependences were measured for the initial film and after irradiation with a low fluence. It was found that at such a fluence, an increase in the critical current for the transition of NbN from the superconducting state to the normal state is observed. It was established that such a small fluence does not influence the critical transition temperature. Keywords: NbN thin films, mixed ion irradiation, critical currents of superconducting films, effect of irradiation on the superconducting properties of films.
