Description
One of the key issues in the operation of a superconducting particle accelerator is the temperature margin of the magnets exposed to heat losses. The temperature margins of the superconducting magnet coils are mainly determined by the heat transfer through the electrical insulation wrapped around the Rutherford-type cables. We have tested the thermal properties of a mock-up representing an accelerator magnet coil with a porous ceramic material in stagnant supercritical helium in steady state condition. In this paper we present the 3D thermal modeling of the experimental mock-up to identify the main heat transfer process and the influence of the geometrical parameters and thermal properties.
