Abstract
Recently, a cryocooler cycle (subsequently referred to as a Stirling/Magnetic Cycle) has been proposed in which refrigeration is produced by thermodynamically cycling both helium and a paramagnetic substance. The two substances alternately regenerate one another, thereby overcoming the low temperature thermal saturation associated with a Stirling Cycle while producing more refrigeration than a simple Magnetic Cryocooler. This paper presents the design of an experimental apparatus which will be used to implement a Stirling/Magnetic Cycle. A computational model of the thermodynamic cycle is used to specify the optimum helium mass and pressure ratio, subject to constraints associated with an existing superconducting solenoid. The remaining components (e.g. heat exchangers, displacer, etc.) are designed around these requirements.
