Description
For more than 50 years CERN-ISOLDE has been producing a wide range of radioactive ion beams (RIBs) using the isotope separation on-line (ISOL) method. Central to ISOLDE’s beam portfolio is its diverse selection of thick target materials and the high energy proton beam (1.4-1.7 GeV) both driving the radionuclide production. Isotopes are generated via spallation, fission and fragmentation reactions and released by heating the target material to ultra-high temperatures (> 2000 °C) in vacuum. Via a transfer line isotopes effuse to the ion source, where they are ionised, formed into an ion beam and send to experimental stations. Ever increasing user demands in terms of yield and beam purity drive the development of target and structural materials. With this contribution, we will give an overview of ISOLDE’s target systems and highlight recent developments, tailored to provide diverse, high-intensity, high-purity RIBs.
