Abstract
Air Liquide, in collaboration with Ecole Normale Supérieure in Paris, has previously developed the theory of an ideal Orifice Pulse Tube Refrigerator, later extended to a complete Double Inlet Pulse Tube. This analytical model permits design of any PTR from only the knowledge of the oscillator characteristics (swept volume, average pressure and working frequency).
One of the first applications of this theory was the conception of a 80K miniature PTR devoted to high Tc superconductors and IR detectors. A 48K limit temperature with 1W available power at 82K were achieved. The 2 cm3 swept volume oscillator is a standard one developped for Stirling machines.
The exhaustive results of such PTR, exhibited during the Paris Show 95 at Le Bourget, are presented and compared to the predictions.
