Abstract

The performance of the Oxford Cryocooler is summarised. This cooler has been developed for space use by the Rutherford Appleton Laboratory and the Departments of Atmospheric Physics and Engineering Science at Oxford University. The design goal of 1/2 watt of cooling power at 80 K for 30 W electrical input power has been exceeded by a substantial amount. The power budget for the compressor and the losses in the displacer are discussed. Graphs of the cold end temperature vs. compressor input power and cooling power are presented.
