Author(s) : BURGER J. F., HOLLAND H. J., MEIJER R. J., et al.

Summary

The authors developed, built and tested a demonstrator of the helium stage under an ESA-TRP contract. This demonstrator has four sorption compressor cells in two compressor stages. Test experiments on this cooler showed that it performs within all specifications imposed by ESA. The cooler delivered 4.5 mW at 4.5 K with a long-term temperature stability of 1 mK and an input power of 1.96 W. So far, the cooler has continuously operated for a period of 2.5 months and has not shown any sign of performance degradation.
