10 K stirling cycle cooler

A two-stage split Stirling Cooler providing 45mW of heat lift at 10.4K with a base temperature at 9.4K. Multiple compressor units are employed to provide cyclic variations of pressure to a single displacer assembly, Vibration cancellation is effected by using compressors arranged in a back-to-back pairs.
