Summary

The XRS cryogenic system is a single photon counting solid-state calorimeter with pixel elements cooled to about 0.065 K by a unique three-stage cooling system. The low temperature is produced by an adiabatic demagnetization refrigerator operating between 0.065 and 1.3 K. The 1.3 K temperature is maintained by a 33-litre helium tank. Graphite/epoxy straps suspend the helium tank from an outer cryogen tank containing 120 litres of solid neon at about 17 K. The neon tank is in turn suspended from the dewar mainshell by low-conductivity straps.
