A new version of TRW's miniature pulse tube cooler system maintains the short wave infrared–focal plane array (SWIR–FPA) (with wavelength spectrum of 0.9–2.5 μm in the hyperspectral imaging spectrometer for the Hyperion Instrument) interface at a temperature of 110 K. The cooler provides ...
An improved pulse tube cooler having a resonator tube connected in place of a compliance volume or reservoir. The resonator tube has a length substantially equal to an integer multiple of ¼ wavelength of an acoustic wave in the working gas within the resonator tube at its operating frequency,...
and the results strongly suggest that Japanese coolers are worth being developed for space use; though, the present input power of 100 W is somewhat large. Displacements of the cold heads during operation depended on the cooler mounting to the base plate and were measured to be ∼3 to 13 ...
The low self induced vibration results from its internal dynamic balancing. It features the ease of integration into an instrument of a small pulse tube cooler. The cooler achieves its 10 W at 95K cooling requirement with substantial margin while rejecting heat to 300K....
