ISOL FACILITY

SPES layout SPES è un Progetto Speciale dell’INFN per la realizzazione di una facility di Fasci di ioni ricchi di neutroni. SPES è il progetto per lo sviluppo della Fisica Nucleare in Italia. Ha un costo valutato di 45 Milioni di euro. Il sito per la realizzaizone del progetto sono i Laboratori Nazionali di Legnaro.

1. Develop a Neutron Rich ISOL facility delivering Radioactive Ion Beams at 10AMeV using the LNL linear accelerator ALPI as re-accelerator .

2. Make use of a Direct ISOL Target based on UCx and able to reach 1013 Fission/s to produce neutron rich exotic beams.

1. Apply the technology and the components of the ISOL facility to develop

applications in neutron production and medicine.

Numeri magici e evoluzione del modello a shell

Stable nuclei: N/Z ≈ 1 - 1.5, Sp ≈ Sn ≈ 6 - 8 MeV Homogeneously mixed protons and neutrons Good mean-field description Good “single-particle” picture (magic numbers) Large gaps between major shells Empirical shell-model interactions

Very neutron-rich nuclei: N/Z ≈ 2 - 2.5, Sn << 1 MeV Diffuseness of neutron distribution (neutron skins & halos)

More states near the Fermi surface Breakdown of the single-particle description Redefinition or disappearance of magic numbers Unknown shell-model interactions

The events originate with the thermal velocity in the region of the UCx disks with a probability given by mcnpx calculations. The beam shape is supposed to be uniform on the disks surfaces

When an atom strike the walls of the container or the disks it is emitted following the cosine law after the “sticking time”

Cyclotron operation principle

Beam hits foil

Electrons are removed

H– becomes H+

Positive charge curves the other way

H+ ions (protons) leave the cyclotron

Easy to add multiple exit ports

By putting the foil at different points, protons are

extracted at any of a wide range of energies.
