Summary

The Resonant Ionization Laser Ion Source (RILIS) is widely used at ISOL facilities for the selective production of isotopes, enabling high-purity beams when combined with mass separation. At INFN-LNL, the SPES project applies this technique to generate radioactive ion beams by bombarding a UCx target with a 40 MeV proton beam.

The SPES Laser Ion Source (SPES-LIS), consisting of a hot cavity and a transfer line, was characterized in two experimental campaigns at ISOLDE Offline 2, CERN. Tests examined its chemical selectivity under different operating temperatures and contaminant ion densities, as well as the influence of high ion density on local ion production.

Results demonstrate the efficiency and selectivity of SPES-LIS, highlighting its capability and importance for ion production at ISOL facilities. Further optimization efforts are being carried out.
