Joule-Thomson cryocooler development at Ball Aerospace.

Author(s) : LEVENDUSKI R., SCARLOTTI R.

Summary

Ball Aerospace is developing a two-stage Joule-Thomson cryocooler for space applications. The on-going Cryogenic On-Orbit Long Life Active Refrigerator (COOLLAR) program began in 1992 and includes producing two Joule-Thomson cryocoolers, a scalability study and a development effort to demonstrate the technology's ability to uniformly cool large interface surfaces. The first cryocooler produced, called the Engineering Development Model (EDM), has undergone extensive testing and is being configurated for a Shuttle flight experiment to verify zero-G performance. The second cryocooler, called the EDM-D1 (for distributed interface), will incorporate the large sensor interface.
