D. Serafini, A. Arzenton et al., The Resonant Ionization Laser Ion Source @ SPES-ISOLPHARM

Targeted Radionuclide Therapy (TRT) is emerging as an alternative to chemotherapy and external beam radiotherapy in the treatment of cancer. In order to produce radiopharmaceuticals for TRT, samples of the desired radionuclide with high specific activity are required. The ISOLPHARM project aims to develop a technique to produce such samples in SPES, the new RIB facility that is under construction at INFN-LNL. In particular, radiopharmaceuticals labeled with Ag-111 radionuclide are under development. Regarding the ion source for this facility, a candidate is the Resonant Ionization Laser Ion Source (RILIS). The theory behind this technology will be presented in this poster together with the latest experiments that were conducted to study the selective laser photo-ionization of the stable isotopes of silver Ag-107 and Ag-109. In these experiments the silver plasmas were produced either in an ablation plume or in a Hollow Cathode Lamp (HCL).
