  1. 545. Air Force Research Laboratory Spacecraft Cryocooler Endurance Evaluation Final Report
    Ms Jordan Armstrong (Glacier Technical Solutions, Air Force Research Laboratory)

    CEC-04 - Cryocoolers (Aerospace)
    Poster Presentation
    The Air Force Research Laboratory (AFRL) Spacecraft Component Thermal Research Group has been devoted to evaluating lifetime performance of space cryocooler technology for over twenty years. Long-life data is essential for confirming design lifetimes for space cryocoolers. Continuous operation in a simulated space environment is the only accepted method to test for degradation. AFRL has...

    CEC-04 - Cryocoolers (Aerospace)
    Poster Presentation
    Multi-stage Stirling pulse tube cryocoolers (SPTC) have great potentials in liquid helium temperatures applications with advantages of high reliability, low vibration, and convenience of stage coupling for lacking cold moving parts. Studies have shown that performance of GM type pulse tubes working at liquid helium temperatures can be improved by introducing DC flow, which decreases...

    CEC-04 - Cryocoolers (Aerospace)
    Poster Presentation
    In recent years, many space missions using cryogenic temperatures are being planed. In particular, a high resolution sensor like Transition Edge Sensor needs very low temperatures below 100 mK. It is well known that Adiabatic Demagnetization Refrigerator (ADR) is one of most useful methods to produce ultra-low temperatures in space because of independence on the gravity. We have studied a...

  4. 306. Theoretical and experimental investigations on impedance of pulse tube cold fingers to match with linear compressors
    Mr Jun Tan (Shanghai Institute of Technical Physics)
    29/06/2015, 14:00
    CEC-05 - Expanders, Pumps, Compressors, and Regenerators
    Poster Presentation
    The impedance match between the cold finger and the linear compressor of the Stirling-type pulse tube cryocooler (SPTC) is significant to optimize the compressor efficiency and to improve the cold finger cooling performance. Several researches ever studied the impedance match and concluded that there existed the optimal acoustic impedance of the cold finger to acquire the highest compressor...
