摘要：

A possible solution for a target system aimed at the production of exotic nuclei as a result of high energy fissions in U-238 compounds has been analyzed. The proposed configuration is constituted by a primary proton beam (40MeV, 0.2mA) directly impinging on uranium carbide disks inserted within a cylindrical carbon box. This system has been conceived to obtain both a high number of neutron rich atoms (originated from about 10(13) fissions/s) and a low power deposition in the target. In order to extract the fission fragments, the box has to be hold at 2000 degrees C. The thermal analysis shows the capability of the thermal radiation to cool the disks with a reasonable margin below the material melting point. Moreover, the analyses of the thermo-mechanical behaviour and of the effusion times confirm the promising features of this target configuration.
