Performance Characterization of the Astrium 10k Developmental Cryocooler
Abstract
To satisfy future Air Force mission requirements, the Air Force Research Laboratory(AFRL), sponsored by the Ballistic Missile Defense Organization (BMDO), led a development program for a proof-of-concept cryocooler designed to support a cooling load of 45mW at 10.4K. Under the technology development program, Astrium (formerly Matra Marconi Space) in Stevenage, United Kingdom, developed a Stirling cycle cryocooler with four Oxford flexure compressors and a two-stage expansion cold end. The cooler was delivered to AFRL, instrumented, and integrated with a 36-inch vacuum chamber for performance characterization and long life endurance evaluation. This paper contains a short description of the cooler's physical components. Also presented are cool down curves, characteristic load lines, and lessons learned during the characterization process. The cooler will enter a long term endurance evaluation after completion of its performance characterization.
