Progress of resonant ionization laser ion source development at GANIL.

SPIRAL2 (Systeme de Production d’Ions Radioactifs Acceleres en Ligne) is a research facility under construction at GANIL (Grand Accelerateur National d’Ions Lourds) for the production of radioactive ion beams by isotope separation on-line methods and low-energy in-flight techniques. A resonant ionization laser ion source will be one of the main techniques to produce the radioactive ion beams. GISELE (GANIL Ion Source using Electron Laser Excitation) is a test bench developed to study a fully operational laser ion source available for Day 1 operations at SPIRAL2 Phase 2. The aim of this project is to find the best technical solution which combines high selectivity and ionization efficiency w…
