Abstract—

The paper describes the Sun-Terahertz space experiment, planned for 2025–2027 on board the Russian segment of the International Space Station. The goals of the experiment are to obtain data on the Sun’s terahertz radiation, as well as to study solar active regions and solar flares. The scientific equipment of the Sun-Terahertz consists of eight detection channels, which are sensitive to radiation of different frequencies in the range of 0.4–12.0 THz. The purpose of this work is to check the compliance of the actual spectral characteristics of scientific equipment with the calculated ones in the operating frequency range of 0.4–20 THz using auxiliary equipment and the developed methodology.
