Abstract:
The luminescence of scintillator screens of Y 3 Al 5 O 12 :Ce 3+ (P46), Gd 2 O 2 S:Tb 3+ (P43), Y 2 O 3 :Eu 3+ (P56) and SrGa 2 S 4 :Eu 2+ (TG-Green) has been characterized when irradiated with deuterium ions and α-particles with energies up to 3 MeV. The relative efficiency of the scintillator layers deposited on stainless steel plates has been studied as a function of beam energy and current as well as ion species. The emitted light first increases linearly with beam energy and then saturates. A logarithmic decay of the efficiency with beam current has been observed for all scintillators. Furthermore, the scintillator degradation by high ion dose has been investigated. Among the screens under study, the TG-Green and P46 scintillators are the best suited materials, in terms of relative efficiency and degradation with ion dose, for fast-ion loss detection in fusion devices.
