Efficient release of radionuclides from solid targets is a key step in radionuclides separation. In this work, the diffusion-effusion release of radioscandium from titanium foils was systematically studied using a dedicated high-temperature vacuum setup. Release efficiencies were measured as a function of temperature and foil thickness and interpreted using diffusion modeling.
Complementary SEM analysis reveals structural differences of the target materials, providing insight into diffusion-controlled release mechanisms.

This work was carried out in the group of Prof. Dr. Andreas Türler.
