First Results on Irradiation of Superconducting Elements for Terahertz Receivers in Deep Space

The primary results of assessing of high sensitive receiving structure based on tunnel SIS (Superconductor-Insulator-Superconductor) and NIS (Normal metal-Insulator-Superconductor) junctions to radiation are presented in this paper. It was shown that irradiation with bremsstrahlung radiation with a dose of 5$\cdot$ 10
