The SPES Project
SPES The main project for the future of LNL is SPES: Selective Production of Exotic Species, in which the dual role of the laboratory as a center for fundamental and applied science is very clear. SPES is a second generation ISOL facility with two main goals: • Production and re-acceleration of exotic beams. Study of nuclei produced in advanced stages of stellar evolution. • production of radioisotopes for nuclear medicine Diego Bettoni Laboratori Nazionali di Legnaro 7
