✦ Synopsis

The design, construction and thermal performance of an LHC Cryostat Thermal Model are described. In place of an LHC prototype dipole cold mass a standard cryostat houses a cold mass with the same overall dimensions, cold surface area, thermal insulation and support systems. The Cryostat Thermal Model is connected to suitably dimensioned end boxes fixing the required temperature levels, by means of saturated helium baths at 1.9 K and 4.2 K, and controlled flows of gaseous helium at 50 to 75 K. Comprehensive instrumentation and fully automatic process control and data acquisition allow precise calorimetric measurements to be performed at all temperature levels.
