Abstract
A pulse tube refrigeration system, having a pulse generator, a regenerator and a pulse tube, comprising a work transfer tube interposed between the pulse generator and the regenerator wherein the work transfer tube has a cross section at the end proximate the pulse generator which differs from the cross sectional area proximate the regenerator, enabling a reduction in heat transfer due to streaming within the work transfer tube.
