The regenerator, typically a microporous structure that is subject to periodic flow of a cryogenic fluid, is the most critical component of Pulse Tube or Stirling cryocoolers, which are widely used for high-demand defense and aerospace applications.

Stirling-type pulse tube cryocoolers (PTC) are often selected for cryogenic cooling applications for their robustness and mechanical simplicity, having no moving parts at the cold end of the cooler. Originally designed for space applications, increas
