Compact, Pulse-Tube Cryocooler
The performance of pulse tube cryocoolers has developed rapidly since the introduction of the orifice by Mikullin in 1984. The proposed effort covers an additional innovation that has been shown to result in increased cryocooler performance. The replacement of the orifice by a room temperature piston allows the phase shifts and displacements to be completely controlled. This control results in cryocooler performance that is equivalent to machines operating on the Stirling Cycle. The focus of this effort is on a cryocooler that can produce 0.5 watt at 65K in a single stage.
