Abstract
Cryostats that operate below 1 K have additional requirements involving the need for extremely small heat leaks and alternative cooling methods. This chapter describes the design and operation of a cryostat operating at 50 mK for the Cryogenic Dark Matter Search experiment. Included are descriptions of the cooling and thermal insulation system, seal design, fabrication and operations. Valuable data is provided on the thermal conductivity of Kevlar and the calculation of joint conductance. The particular issue of using only radiopure materials in the cryostat construction is also covered. A list of lessons learned from the cryostat operation is provided.
