Summary

A single stage reverse Brayton cryocooler using miniature high-speed turbomachines recently completed a successful space shuttle test flight demonstrating its capabilities for use in cooling the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) on the Hubble Space Telescope. The NICMOS cryocooler is designed for a cooling load about 8 W at 65 K, and comprises a closed loop cryocooler coupled to an independent cryogenic circulating loop. Future space applications involve instruments that will require 5-200 mW of cooling at temperatures between 4 and 10 K. The paper discusses the extension of Turbo Brayton technology to meet these requirements.
