characteristic frequencies cyclically operating cooler have been studied. Theoretical and experimental smoothing techniques of temperature fluctuations and evaluated the efficacy of passive inertial method have been developed. As a result of the proposed package of measures the degree of influence of the cooling mode DC-cooled mixer is reduced ~ 20 times. Some technical solutions for development of high sensitive superconducting THz receivers with mechanical coolers have been formulated. Key words: THz waves, superconducting receivers, cryogenics, refrigerators, thermal stabilization, space telescope. ()
