Description
The effective thermal conductivity in the transverse direction is one of the less predictable coil parameters. In the framework of the construction of a high field solenoid (18 Tesla - 100 mm free bore at 4.2 K) at the LASA lab, the authors built an experimental apparatus for measurements of thermal conductivity of pure materials as well as of composites and coil blocks, the main aim of the experiment being the measurements of the thermal conductance of pieces of real NbTi and Nb3Sn windings. This paper starts with a discussion of how the thermal conductivity affects quench properties of superconducting magnets. The main features of the experimental apparatus are described together with a calculation and a measurement of the thermal loss. Finally the preliminary measurements on some pure materials as well as on a coil block are presented
