CRYOSTATTED PHOTODETECTING SYSTEM FOR EXTRA- ATMOSPHERIC ASTRONOMY, SPACE EXPLORATION, AND REMOTE EARTH SOUNDING

摘要

FIELD: astronomy and space research engineering. SUBSTANCE: system has Stirling cooler cold conductor mounting solid state television photoelectric converter, heat-transfer circulating loop, and double-valve bellows membrane pump with reciprocating drive. Container holding melting cryogenic material is secured on heat shield with aid of low-heat-conducting supports made of glass-reinforced plastic and heat-insulated from cooler by means of low- heat-conductivity capillary tubes. Cryogenic liquid circulating in heat- transfer loop has triple-point temperature much lower than melting point of cryogenic material and its normal boiling temperature is much lower than triple-point temperature of melting cryogenic material. Cold conductor carrying solid state television photoelectric converter is also secured on heat shield with aid of low-heat-conductivity supports made of glass-reinforced plastic and heat-insulated from container holding melting cryogenic material by means of capillary tubes made of low-heat- conductivity material. Proposed system will ensure continuous operation of solid state television photoelectric transducer for 3 to 5 years. EFFECT: enhanced reliability of system. 1 cl, 3 dwg
