In ISOL systems, the target material temperature dominates the release process and limits the primary beam intensity. Heat is dissipated from the beam spot through the target material, making the effective thermal conductivity of the target material critical for the ISOL process. Specifically-engineered microstructures have the potential to achieve better release properties. To address the thermal challenges in target materials, a deeper understanding of the thermal conductivity of these engineered materials is required.

In this work, a numerical method is developed for evaluating the effective thermal conductivity of representative microstructures. Separately, a steady-state experimental-numerical method is used to determine the effective thermal conductivity of porous β-SiC slip-cast material and β-SiC pressed pellet material. In addition, a new experimental apparatus for effective thermal conductivity is presented from conceptual design to commissioning.
