“…This model introduced by K. Michaelian and A. Menchaca-Rocha [46] leads to a maximum electron energy deposition density, quenching density (ρ q ), above which saturation of luminescence centers occurs. Figure 7 shows a similar dependence of the screen efficiency on the ion flux to those reported by D. Broggio et al [47] and explained by the luminescence quenching above the maximum energy deposition density, ρ q . This luminescence quenching must be taken into account when developing fast-ion loss detector for fusion burning plasma devices with large populations of fast-ions such as ITER.…”

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.

“…The experiments have been carried out at the HIMAC facility (Heavy Ion Medical Accelerator in Chiba) of the NIRS (National Institute of Radiological Sciences, Chiba, Japan). Prior to this work we have shown that the ion-induced degradation of the scintillation intensity can be neglected for fluence lower than 10 12 ions/cm 2 [11]. We present the dosimeter prototype and its response under ion beam.…”

We present a dosimeter prototype, devoted to ion beam dosimetry, tested with Helium, Carbon and Neon ions having an equivalent range in water of 150 mm. A polyvinyltoluene based plastic scintillator is used to convert the deposited energy into scintillation, a measurement probe and a long optical fibre guide the light to a photon counting unit. Using 10-40 µm thick scintillators we show that the dosimeter gain is enough to provide useful measurements, the ion-induced scintillation can be interpreted using a model taking into account the energy deposited by secondary electrons. For a practical purpose it is shown that a linear relationship can be established between the scintillation signal and the relative dose.
