Abstract
The thermal conductivity of a combination of glass fibre tape and mica/glass sheetas insulation for superconducting Nb3Sn cables for a fully impregnated accelerator dipole magnet has been investigated. At 4.3 K a value for the thermal conductivity coefficient of 45 mW/m/K has been found, which is a considerable improvement compared to values of 5–15 mW/m/K if only mica/glass sheet is applied. An improved resin penetration to both sides of the mica/glass sheet not only increases the thermal conduction and therefore the stability margin of the superconductor, but it also enhances the shear strength of the insulation layer.
