Abstract
A cryocooler cold head regenerator having a series of discrete sections formed from particles of tin-antimony, particles of holmium copper, particles of gadolinium oxysulfide, and particles of gadolinium aluminate. Each section is separated from an adjoining section by a multi-layer screen formed from a stacked layers of copper mesh, felt, phosphor bronze mesh, and brass mesh. A cryocooler outfitted with regenerator can have an increased heat capacity to achieve temperatures in the cold head below 2.3 K with optimized heat lift at 3 K.
Claims13
A regenerator for a cryocooler, comprising:
- a first section comprised of an amount of tin antimony particles;
- a second section comprised of an amount of holmium copper particles;
- a third section comprised of an amount of gadolinium oxysulfide particles;
- a fourth section comprised of an amount of gadolinium aluminate particles;
- and
- a series of multi-layer screens positioned between the first section and the second section, the second section and the third section, and the third section and the fourth section, wherein each of the multi-layer screens includes at least one layer formed from a non-conductive material having a plurality of randomized flow channels.
