Book excerpt: Experimental studies are under way at the Oak Ridge National Laboratory (ORNL) which are designed to measure the time evolution, ionization efficiencies, and release efficiencies of implanted elements diffused from refractory target materials which are candidates for forming radioactive ion beams (RIBs) at the Holifield Radioactive Ion Beam Facility (HRIBF). The diffusion coefficients are derived by comparing experimental data with numerical solutions to a one-dimensional form of Fick's second law for ion implanted distributions. In this report, we describe the experimental arrangement and provide time release data and diffusion coefficients for releasing ion implanted Cl from Zr5Si3 and 75As, 79Br, and 78Se from Zr5Ge3.
