Inertance Pulse Tube Cryocoolers make use of a long tube for phase shifting and optimization of performance. This long tube presents a challenge for packaging in most applications, and is also a concern for environments where vibration is present (e.g., launch). In the present invention, a gap configuration is used in place of the tube, resulting in a more compact inertance device. Using the SAGE software, the performance of this new device is found to be comparable to that of an inertance
more » ... Significantly, this new invention offers the flexibility to change the inertance value during testing and operation, which cannot be done with the tube configuration.
