LABORATORI NAZIONALI DI LEGNARO
In the ISOL method a primary ion beam bombards a hot target where radioisotopes are generated through nuclear reactions. Those diffuse out of the target and effuse along the (eventually chemically selective) transfer lines up to an ion source. Once ionized, the radioisotopes are pulled out of the target-ion source unit and are then accelerated to suitable energies and directed towards experimental stations where research in nuclear physics, nuclear astrophysics, solid state physics or atomic physics is carried out. The forefront research programs of those disciplines demand highly exotic probe nuclides with sufficiently high intensities to attain accurate measurements. An end-to-end simulation that integrates all processes is key to optimize targets for efficient release of exotic species. The Radioactive Ion Beam Optimizer (RIBO) Monte Carlo code was created in 2000 to address this need, and quickly became the reference tool for ISOL target design. This presentation shows the different physics processes relevant to the design of target-ion sources and describes the current status of the RIBO code.
