Abstract
The thermal insulation characteristics of a single-shield cryostat have been studied in terms of liquid helium evaporation loss rate. An aluminum thermal radiation shield was used and then substituted with a pitch CFRP one. The evaporation loss increased by a mere 7% at the cryostat operating point. Prior to this, the temperature dependency of both the thermal conductivity of CFRP and the electric resistivity of carbon was studied in order to decide on the type of pitch to use for the shield.
