The SPES Radioactive Ion Beam (RIB) facility at INFN-LNL is presently in the construction phase. The aim of the SPES project is to provide high intensity and high-quality beams of neutron-rich nuclei to perform forefront research in nuclear structure, reaction dynamics and interdisciplinary fields like medical, biological and material sciences. SPES is a second generation ISOL radioactive ion beam facility. It represents an intermediate step toward the future generation European ISOL facility EURISOL. The SPES project is part of the INFN Road Map for the Nuclear Physics; it is supported by the Italian national laboratories LNL (Legnaro) and LNS (Catania). It is based on the ISOL method with an UCx Direct Target able to sustain a power of 10 kW. The primary proton beam is delivered by a Cyclotron accelerator with an energy of more then 40 MeV and a beam current of 200 μA. Neutron-rich radioactive ions will be produced by Uranium fission at an expected fission rate in the target of the order of 10¹³ fissions per second. The exotic isotopes will be re-accelerated by the ALPI superconducting LINAC at energies of 10 MeV/n and higher, for masses in the region of A=130 amu, with an expected rate on the secondary target of 10⁷-10⁹ pps. The scientific program, the status and the perspectives of the project will be presented together with the related detector developments.
