The SPES multi-foil direct target.

A solution for a target aimed at the production of exotic nuclei will be analyzed. In the proposed configuration a primary proton beam (40 MeV, 0.2 mA) directly impinges on uranium carbide disks. The exotic nuclei are produced as a result of high energy fissions in 238U compounds. The system has been conceived in order to obtain both a high number of neutron-rich atoms, originating from about 1013 fissions s-1 and a low power deposition in the target. The target container is held at about 2000 °C in order to maximize the number of extracted fission fragments
