“…These coolers offer the high-reliability of space-flight cryocoolers at a much lower cost, thus enabling cryogenic cooling in low-cost instruments. In 2014, JPL performed environmental qualification and characterization testing on the LPT9510 [1,2] and LPT9310 [3,4]. In 2016, Thales, in collaboration with JPL, developed a high-performance (HP) version of the LPT9310 that was optimized to provide cooling at 60 K and preserved the form, fit and flight-qualified elements of the COTS LPT9310 [5].…”

Two Thales LPT9310-HP commercial off-the-shelf (COTS) cryocoolers were parametrically performance tested for cold tip temperatures between 50 K and 250 K and heat rejection temperatures between 0°C and 40°C. Both coolers had identical transfer line configurations. The test results revealed small unit-to-unit thermodynamic performance variation. They are compared to test results of a COTS LPT9310 cooler with the same transfer line configuration. The effect of compressor temperature and pulse tube inclination angle are also discussed. In addition, the off-state heat leak as a function of inclination angle is presented. Finally, the feasibility of using a single LPT9310-HP COTS cooler in a two-stage configuration is discussed.

Four Thales LPT9310 and four Thales LPT9510 commercial off-the-shelf (COTS) cryocoolers were parametrically performance tested. The LPT9310 coolers had transfer lines of various lengths while the LPT9510 coolers all had the same transfer line geometry. The LPT9510 test results revealed unit-to-unit thermodynamic performance variation, quantified the effect of compressor temperature on thermodynamic performance and quantified the heat flow distribution between the compressor and expander as a function of their temperature distribution. The LPT9310 test results revealed the optimal drive frequency as a function of transfer line length, quantified the effect of heat rejection temperature distribution on thermodynamic performance and enabled the development and verification of a thermodynamic performance prediction tool that accounted for cold tip temperature, heat lift, heat rejection temperature and transfer line length.
