To investigate exotic cluster structures in neutron-rich nuclei via break-up reactions on a light target, the CLIR experiment was performed at INFN - Laboratori Nazionali del Sud (LNS). To this aim, a Radioactive Ion Beam (RIB) was produced, by means of the FRIBs@LNS facility, exploiting the In-Flight fragmentation technique: in this way, the obtained beam contains several radioactive ions of interest, such as He-6, Li-7,Li-8,Li-9, Be-11,Be-12, B-13,B-14,B-15,C-17, and even the C-16 and Be-10 isotopes, for which cluster structures have already been studied at LNS. The isotopes of the cocktail beam were identified by means of the Delta E-ToF method, and afterward break-up reactions were triggered by sending them on a (CH2)(n) polyethylene (protons) target; the reaction fragments were detected by the high-granularity fetntoscope array FARCOS coupled with the CHIMERA 4 pi multidetector. In this paper an overview of the status of the experiment will be given, and in particular the calibration procedures developed for the tagging detector and for the FARCOS array will be described.

Abstract

To investigate exotic cluster structures in neutron-rich nuclei via break-up reactions on a light target, the CLIR experiment was performed at INFN - Laboratori Nazionali del Sud (LNS). To this aim, a Radioactive Ion Beam (RIB) was produced, by means of the FRIBs@LNS facility, exploiting the In-Flight fragmentation technique: in this way, the obtained beam contains several radioactive ions of interest, such as He-6, Li-7,Li-8,Li-9, Be-11,Be-12, B-13,B-14,B-15,C-17, and even the C-16 and Be-10 isotopes, for which cluster structures have already been studied at LNS. The isotopes of the cocktail beam were identified by means of the Delta E-ToF method, and afterward break-up reactions were triggered by sending them on a (CH2)(n) polyethylene (protons) target; the reaction fragments were detected by the high-granularity fetntoscope array FARCOS coupled with the CHIMERA 4 pi multidetector. In this paper an overview of the status of the experiment will be given, and in particular the calibration procedures developed for the tagging detector and for the FARCOS array will be described.
