Abstract
A regenerator material for use inside a displacer of a Stirling cycle cryocooler includes a plurality of circular disks formed from a synthetic felt that is preferably polyester. The plurality of disks have an outer diameter that is greater than the inner diameter of the displacer. The plurality of circular disks form a stack within the displacer. The regenerator material minimizes operational variation between different cryocoolers. In addition, the regenerator material can be easily filled into the cryocooler displacer.
