Degradation of the scintillation yield of anthracene under high-fluence carbon ion beams

Scintillation degradation of YAG: Ce under low-energy ion bombardment

“…5a, we do not find a significant energy dependence of k within the experimental uncertainty. In addition, the nearly constant value of k is considerably small compared to other scintillators [9]. It reveals that the YAG: Ce scintillator exhibits much higher resistance to radiation damage.…”

“…In 1951, Birks and Black published an empirical formula to describe the luminescence efficiency of the scintillator bombarded by Helium ion beams. This empirical formula has been tested for many scintillator materials, such as anthracene, Y 2 O 2 S:Eu, Gd 2 O 2 S:Tb and YAG:Ce [19][20][21]. The Birks model was derived from the idea that the luminescence of a scintillator is the result of a competition between the emission of photons from undamaged molecules and the absorption of photons by damaged molecules.…”

Ion-induced degradation of BC-418 scintillation yield

“…The emission band, resulting from dyes scintillation, is between 350 and 420 nm. We briefly describe the experimental set-up, about which more details can be found in Broggio et al (2005). Samples were held in a small-volume chamber onto a sample holder allowing positioning at 45 • with respect to the beam axis.…”

“…In most cases, the deterioration of scintillating properties has been studied using electron or photon irradiation (Busjan et al, 1999;Hamada et al, 1999;Vasil'chenko et al, 1996;Holm et al, 1999). In a recent paper (Broggio et al, 2005) we have presented a simple experimental set-up for the study of the degradation of the scintillation yield under ion beam irradiation. This device has been used to study the degradation of the scintillation yield of the PVT-based plastic scintillator, BC-418, under lithium, carbon, and iodine ions at different energies, in order to cover a large scale of energy loss.…”

High-temperature scintillation of alumina under 32 MeV 63Cu5+ heavy-ion irradiation

“…2), the empirical Birks model was used according to [18,22]. Using Poisson's equation, the defined ratio x of damaged material area A D to non-irradiated material A P will exponentially increase as a function of fluence U (Eq.…”
