The construction of the Radioactive Ion Beam (RIB) Facility SPES-DT, within the framework of the new European RIB panorama is under study at the Laboratori Nazionali di Legnaro. The present project will be devoted to the production of neutron rich exotic nuclei, by using the fission process induced by a 40 MeV proton beam, 200 μA current, on a multi-sliced Uranium Carbide (UCx) target. The UCx multiple thin disks target, developed at LNL is designed so that the power released by the proton beam is mainly dissipated by irradiation. Following the idea of the existing HRIBF facility at Oak Ridge National Laboratory (USA) where a proton primary beam of 40 MeV is also used, our target configuration is an evolution which permits to sustain a higher power on target. A high number of fission products (up to 1013 fission/s) will be obtained, still keeping a low power density deposition inside the target. The whole facility, together with the details on the Direct Target configuration, will be described. Thermo-mechanical calculations, pellets preparation and characterization, effusion-diffusion model predictions for the estimation of the release fraction of different radioactive nuclides will be discussed. A scaled (1:5) prototype of the Target system has been built and tested recently at HRIBF. [ABSTRACT FROM AUTHOR]

The EXCYT facility (EXotics with CYclotron and Tandem) at the INFN-LNS is based on a K-800 Superconducting Cyclotron injecting stable heavy-ion beams (up to 80 MeV/amu, 1 eμA) into a target-ion source assembly to produce the required nuclear species, and on a 15 MV Tandem for post-accelerating the radioactive beams. Since December 1999 the Superconducting Cyclotron operates in a stand-alone mode by means of the new axial injection beam line. The primary beam line has been already mounted and tested. The part of mass separator on the two high-voltage platforms together with low intensity diagnostics is already installed while the ancillary items along with the part of mass separator at ground potential will be installed during the next stop of accelerator operations. The target-ion source unit has been successfully tested on-line at GANIL. The goal of such efforts will be represented by the test of the mass separator with stable beams planned at LNS by the end of the year. The commissioning of the EXCYT facility is foreseen in 2004 together with the start of nuclear experiments program. © 2004 American Institute of Physics [ABSTRACT FROM AUTHOR]
