Abstract

Pulse tube cryocoolers (PTC) can be regarded as the next step in the development of the Stirling cooler. The major advantage vs. the Stirling cooler is the omission of any moving part in the cold head, resulting in significantly increased MTTF. Further advantages are higher mechanical robustness and stability and the potential for cost reduction. AIM developed PTC's for several years in close cooperation with the University of Giessen. As a recent result at AIM, Coaxial PTC cold head are available within the outline dimension of typical IR Stirling cold head of 13mm diameter. The achieved performance data are comparable to the serial data of the Stirling cold head. This PTC cold head is designed to be operated in the orifice mode without a double inlet which is known to cause instabilities. Technical details and performance data represent the current technical status at AIM.
