Description
Air Liquide has been working with ESA, CEA and Thales Cryogenics since 2010 to design, manufacture and test a 15K Pulse Tube Cooler system.
This cooler is particularly adapted to the pre-cooling needs of cryogenic chains designed to reach 0.1-0.05K for focal plane cooling on scientific space missions such as ATHENA.
The cooler is designed to provide cooling power >0.3W at temperatures from 15 to 18K with an electrical power budget less than 300W (excluding electronics) and a 288K rejection temperature. Significant cooling power at an intermediate temperature (typically 80-100K) is also available.
The design includes two cold fingers mounted on a common warm flange driven by a single high power compressor (240W PV power) specially developed for this application. The first cold finger is used to pre-cool the second, low temperature stage.
An Engineering Model has been manufactured and the design and test results will be presented in this paper.
