Cryocooler Efficiency Trends (Measured Data and Development Goals)
HCC Cryocoolers for DoD Missions are Further Expanding the Technology Base • DoD Missile Defense Agency missions desire large cooling capacities: • 2 W at 35 K …plus • 20 W at 85 K • Large "Oxford style" pulse tube cryocoolers have been developed at NGST and Lockheed Martin for this need with input power capacities up to 600 watts • These large-capacity coolers provide near-flight-qualified hardware for future NASA missions to build upon NGST (TRW) HCC 35K/85K 2-stage pulse tube cryocooler (14 kg, 600 W) LM HCC 35K/75K 2-stage pulse tube cryocooler (1.65W@ 35K, 18W @75K, 500W
