Abstract
Gifford-McMahon (G.M.) like pulse tube (P.T.) refrigerators are under development at CEA/SBT. The pressure oscillation in the P.T. is generated by a commercial helium compressor associated with a rotating distribution valve. The P.T. are operated at low frequency (1–2 Hz) and their performance and potential applications are close to those of conventional G.M. cryorefrigerators.
A single stage prototype achieving an ultimate temperature of 26 K and producing a net cooling power of 100 W at 80 K has been developed. The effective performances have been compared to the prediction of a theoretical model. The influence of geometrical parameters and P.T. inclination have been extensively studied. The contribution to parasitic heat input of gas permanent flow has also been evaluated.
A double stage prototype is presently under tests with the aim to achieve a simultaneous cooling power of 7 W at 20 K and 40 W at 80 K.
To prepare the future development of a 4 K multistage P.T., the characterisation of a 20 K-4 K stage using a rare earth regenerator has been performed. Some experimental results are compared to model predictions. An ultimate temperature of 3.5 K has been achieved with a net cooling power of 30 mW at 4.5 K.
