WebFeb 14, 2024 · The two-stage Flight Cryocooler consists of two Cryogenic Control Electronics (CCEs), one Redundancy Switch Electronics (RSE), a Thermo Mechanical Unit (TMU) and a flight harness set. For TIRS-2, Ball developed redundant electronics and incorporated many design and manufacturing improvements to simplify the fabrication … WebJun 20, 2011 · LDCM Thermal Infrared Sensor (TIRS) Cryocooler. The Cryocooler is like a big refrigerator, except that it cools to cryogenic temperatures (below −150°C, −238°F or 123K). It is responsible for cooling our detectors to 43K (-382F). This is very cold and the temperature at which we must maintain our detectors in order to get optimal thermal ...
