Low temperature thermal conductivity measurements on longitudinal and transverse sections of a superconducting coil

Thermal conductivity measurements have been performed on longitudinal and transverse sections of a superconducting coil at 5, 79, 196, and 276 K. The composite coil sections are composed of copper-stabilized niobium—titanium wire embedded in epoxy. Tabular and graphical data are presented. These data are compared to values calculated on the bases of components of the coil sections. Reasonably good agreement is obtained.
