Abstract
A unitary pulse tube expander for removable attachment to a SADA II coldfinger and insertion within a Dewar assembly. The regenerator of the pulse tube expander is encased in a regenerator sleeve and a cold cap to create a unitary pulse tube expander that may function as a drop-in replacement for a Stirling type expander in a SADA II coldfinger cryocooler.
