Target selection for the HRIBF project
- Joint Inst. for Heavy Ion Research, Oak Ridge, TN (United States)
Experiments are in progress at the Oak Ridge National Laboratory which are designed to select the most appropriate target materials for generating particular radioactive ion beams for the Holifield Radioactive, Ion Beam Facility (HRIBF). The 25-MV tandem accelerator is used to implant stable complements of interesting radioactive elements into refractory targets mounted in a high temperature FERIAD ion source which is on-line at the UNISOR facility. These experiments permit selection of the target material most appropriate for the rapid release of the element of interest, as well as realistic estimates of the efficiency of the FEBIAD source. From diffusion release data, information on the release times and diffusion coefficients can be derived. Diffusion coefficients for Cl implanted and diffused from Zr{sub 3}Si{sub 3} and As, Br, and Se implanted into and diffused from Zr{sub 3}Ge{sub 3} have been derived from the resulting intensity versus time profiles.
