Linear Motor Driven Stirling Coolers for Military and Commercial Applications 929171

This paper discusses the design and performance of a miniature, closed cycle, split Stirling, cryogenic cooler that provides 1 watt of cooling at 80 K. The compressor uses two opposed linear motors to drive opposed pistons and the expander uses a pneumatically driven displacer. A single electronics module and compressor has been developed to drive three different expanders that have nominal cold cylinder diameters of 5, 8 and 13 mm.
