The Radioactive Beam Diagnostics at LNS - INFN | |
|

| At LNS - INFN Catania, two complementary facilities for Radioactive Ion Beams have been developed in recent years. They exploit the two techniques known as Isotope Separation On Line (ISOL) and In Flight Fragmentation, with a primary beam accelerated by means of the LNS Superconducting Cyclotron. EXCYT makes use of the ISOL technique to produce the radioactive beams, with an energy up to 7 AMeV. FRIBs uses the In-Flight technique, with an energy up to 60 AMeV. The intensity is well below to the levels of the standard stable beams, being tipically below 106 pps. The standard beam diagnostics cannot be used, because of the low signal to noise ratio. An efficient beam diagnostics has been therefore developed and installed, well suited for our low intensity radioactive beams. It permits an accurate check in real time of the beam, such as the profiles, the intensity and the isotope identification along the beam lines, thus allowing the optimization of the transmission until to the experimental halls. The devices are based on nuclear particle detectors, in particular on position sensitive silicon detectors (PSSD), germanium detectors, scintillators and scintillating optical fibres. | ||
