Optimization of a hot-cavity type resonant ionization laser ion source

subject

description

TuePS05; International audience; Resonant Ionization Laser Ion Source (RILIS) is nowadays an important technique in many RadioactiveIon Beam (RIB) facilities for its reliability and ability to ionize efficiently and element selectively.Grand Accélérateur National d’Ions Lourds (GANIL) Ion Source using Electron Laser Excitation(GISELE) is an off-line test bench for RILIS developed to study a fully operational resonant laserion source at GANIL facility. The ion source body has been designed as a modular system toinvestigate different experimental approaches by varying the design parameters, to develop the futureon-line laser ion source. The aim of this project is to determine the best technical solution whichcombines high selectivity and ionization efficiency with small ion beam emittance and stable longterm operation. Latest results concerning emittance and time profile development as a functionof the temperature for different ion source versions will be presented.
