I. Introduction
Radioactive Ion Beams (RIBs), especially in the case of nuclei far from the stability valley, open new horizons in nuclear physics. Therefore, since the last decade, many facilities around the world have upgraded or are upgrading their infrastructures in order to produce beams of large intensity (106 pps or higher). New ones are presently under construction and will go into operation in this decade. Τhe upgrade [1] of the superconducting cyclotron located at Laboratori Nazionali del Sud of INFN in Catania includes the construction of a new Radioactive Ion Beams facility, named FraISe (FRAgment In-flight SEparator) [2], [3], [4]. The facility produces RIBs, whose intensities vary in the range from about 103 particles/s for nuclei far from the stability valley, up to about 107 particles/s for nuclei close to the stability valley. The facility is based on the in-flight technique in which a primary beam impinges on light Be or C targets. FraISe makes use of primary beams of light and medium masses with power up to ≈ 2–3 kW [5].
