Cheng He,Yun-jin Yao,Xue-song Yeent sizing have been incorporated into this second generation design. The quantitative improvement provided by those design changes is presented. The second generation cold head design is currently being incorporated into a flight design warm-end expander motor assembly with Oxford-class flexure and

Ball Aerospace 4–10 K Space Cryocoolers under development for the NASA James Webb Space Telescope (JWST), Terrestrial Planet Finder (TPF), and Constellation X-Ray (Con-X) missions. The 4–10 K coolers are highly leveraged off previous Ball space coolers including multiple life test and flight units.

A Study of the Use of 6K ACTDP Cryocoolers for the MIRI Instrument on JWSTlessons learned and performance achieved in the MIRI cryocooler application. In the final proposed configuration, all of the MIRI/JWST design considerations were successfully met. Although the cryocooler option was eventually deselected in favor of a solid-hydrogen stored cryogen system, the cryocoo

Development of a Small-Scale Collins-Type 10 K Cryocooler for Space Applications View based control algorithm. In parallel to this effort, a manufacturing method was developed to enable production of very long continuous lengths of small bore finned tubing. This tubing is used in the highly effective recuperative heat exchanger associated with each stage of the cryocooler. A th
