Thermal design of the XRS helium cryostat.

Summary

The X-Ray Spectrometer (XRS) system is a hybrid neon/helium system with a final stage of cooling provided by an adiabatic demagnetization refrigerator. The thermal design of the helium cryostat is described. To achieve a lifetime of 2.5 years with a helium volume of approximately 20 litres, the heat load on the helium must be of the order of 800 microwatts or less.
