Description
The spectroscopy of decay products is one of the three pillars of low-energy beam exploitation techniques produced by the ISOL method. Decay stations can be found in all facilities using the ISOL technique to produce radioactive beams, such as ALTO (France), ISOLDE (CERN), and IGISOL (Finland), as well as in future facilities like SPES (Italy) and DESIR (France), to name a few in Europe
In the context of β decay, it is important to note that the total energy released during this process, denoted as Qβ , can exceed 10 MeV as we venture further from nuclear stability. At the same time, the energy required to remove a neutron (Sn) decreases, resulting in the emission of unbound neutron(s) alongside the expected γ-rays.
Elpasolite crystals containing 35Cl such as CLYC:Ce represent a promising way to detect and discriminate both neutrons and γ-rays coming from such decay while measuring their energies. The ANR project SENSE (Scintillating Elpasolite for Neutron Spectroscopy Enhancement) aims to study such crystals using detailed Geant4 simulations in association with experimental measurements.
We started this project using a 3" × 4" CLYC:Ce crystal in order to measure several physical quantities such as its resolution, efficiency and homogeneity. Those measurements were first performed for gamma only and are combined with simulations performed via Geant4 for comparaison.
So far, the study of neutron interaction with the crystal is being studied and experiments using ALTO facilities are planned. Also, Geant4 does not implement well the cross-section of neutron interacting with chlorine and this part of the work is still in progress. Our presentation will share the results we have obtained for this CLYC crystal and the on-going work that is performed at IJCLab.
