Abstract
The FRIBs facility at the Laboratori Nazionali del Sud produces, since 2001, Radioactive Ion Beams (RIBs) at intermediate energies by projectile fragmentation. Using such beams nuclear physics experiments of international relevance have been accomplished so far. The fragments of interest are selected along the extraction line of the superconducting cyclotron, configured as a fragment separator. RIBs rates up to 105 ion/sec on target have been successfully achieved by a cyclotron primary current up to 600 enA. However a possible upgrade of the production and selection system has been studied and it is going to be realized in the next months. Features of the upgrade and the expected improvements in RIBs production yields and transmission are reported.
