The SPES project at Laboratori di Legnaro of INFN (Italy) is concentrating on the production of neutron-rich radioactive nuclei by the Uranium fission at a rate of 1013 fission/s. The emphasis to neutron-rich isotopes is justified by the fact that this vast territory has been little explored in the last years. The Radioactive Ion Beam (RIB) will be produced by ISOL technique using the 40 MeV proton-induced fission on a Direct Target of UCx. The most critical element of the SPES project is the Multi-Foil Direct Target. Up to day the proposed target represents an innovation in term of capability to sustain the primary beam power of about 8kW. The reaction products are extracted from the target by thermal process, ionized and injected into the re-accelerator stage. During the talk will be presented the recent developments on the fabrication, characterization, and on-line testing of carbide targets. In addition, developments related to the ion-source activities using the surface, plasma and laser ion sources technique it will be reported. Finally, will be shown the experimental test results on target remote handling.
