Abstract

The cooling of infrared sensors and electro-optical devices by Joule-Thomson cryostats has been a viable systems option for electro optical systems since the 1960's. Currently, other options such as thermal electric coolers, closed cycle coolers and non-cooled detector technology are available and present alternatives for the system designer. In specific applications, Joule-Thomson cryostats still prove to be the option of choice. This paper will discuss the current and projected applications for Joule-Thomson cryostats as well as define and discuss the advantages of Joule-Thomson cooling technology. The importance of contamination control, reliability, and `Total Quality Management' in the manufacturing of Joule-Thomson cryostats will be emphasized.
