“…There are a variety of investigations that have obtained values of k B for the equivalent scintillation material NE-102 from experiments with other particles and/or gamma-rays of higher energy. Badhwar et al 22 analyzed in 1967 results by different authors and concluded that most of the results [41][42][43][44][45] could be fitted with Eq. (4) and k B ≈ 10 mg MeV −1 cm −2 although in some experiments k B values were obtained that were considerably lower.…”

Energy dependent response of plastic scintillation detectors to photon radiation of low to medium energy

The energy response was quantified relative to the response to (60)Co which is the common radiation quality for the calibration of therapy dosemeters. The observed energy dependence could be well explained with the assumption of ionization quenching as described by Birks' formula. Plastic scintillation detectors should be calibrated at the same radiation quality that they will be used at and changes of the spectrum within the application need to be considered. The authors results can be used to evaluate the range of validity of a given calibration.

“…Experimental studies, performed with ions of a few MeV/nucleon, as heavy as those from Boron to Neon [10,11], have shown that the scintillation efficiency 6 of alkali halide crystals (NaI(Tl), CsI(Tl)) is not a function of −( dE/ dx) e alone, but instead, is composed of a series of discrete functions, one for each incident particle. The observation has been thoroughly analyzed by Murray and Meyer [12], as shown in this subsection.…”

A simple formalism describing the light response of CsI(Tl) to heavy ions, which Preprint submitted to Elsevier Preprint 22 October 2018 quantifies the luminescence and the quenching in terms of the competition between radiative transitions following the carrier trapping at the Tl activator sites and the electron-hole recombination, is proposed. The effect of the δ rays on the scintillation efficiency is for the first time quantitatively included in a fully consistent way. The light output expression depends on four parameters determined by a procedure of global fit to experimental data.

“…Par ailleurs, les expressions de Birks et de Wright ne tiennent pas compte des effets primaires induits par le passage des particules ni des deux signaux de la scintillation. Divers auteurs [2,[7][8][9] ont d'autre part souligné que ces relations ne permettent pas d'interpréter l'ensemble des observations expérimentales concernant le rendement de la scintillation qui ont été publiées, notamment dans le cas de rayonnements de pouvoir ionisant élevé. Les résultats cités dans ces travaux étaient cependant très fragmentaires et ne portaient que sur la mesure de la scintillation globale sans chercher à la décomposer en ses deux composantes.…”

“…Pour des ions lourds (protons, particules a) de pouvoir ionisant élevé nous retenons l'idée de l'existence des régions activées par des électrons secondaires rapides ayant échappé à une colonne primaire constituée autour du corpuscule incident [2,7,35 La trace ainsi que les blobs, constituent donc les régions caractérisées par une densité élevée en activations où nous admettons que la dégradation des excitons S1 et T, est très probable.…”

2014 On présente une étude de l'influence de la nature des particules ionisantes sur le rendement de la radioluminescence en considérant la scintillation globale et ses deux composantes (prompte et différée). Une expression donnant la luminescence spécifique dS/dx en fonction du nombre de charges z et de la perte d'énergie spécifique du corpuscule incident a été établie d'après un modèle de la trace qui tient compte de conclusions récentes sur la nature, l'évolution et la distribution des excitations primaires créées dans le milieu par le passage d'une particule chargée. L'accord entre les courbes théoriques déduites au cours de cette étude et les courbes expérimentales précédemment publiées a été vérifié et a permis de déterminer les divers paramètres qui interviennent dans les relations proposées. On montre que les valeurs ainsi obtenues sont en accord avec les données de la littérature et qu'elles se justifient théoriquement. Abstract. 2014 The influence of the nature of ionizing particles on the radioluminescence yield of aromatic scintillators is studied. Both prompt and delayed scintillation components are considered. An expression giving the specific luminescence dS/dx as a function of the charge number z and of the incident particle specific energy loss has been derived, following a track model published before, that is consistent with recent conclusions about the nature, evolution and distribution of the primary excitations created by an ionizing particle in the organic scintillator. The good agreement between the theoretical curves derived in this paper and the experimental ones previously reported provided us with a means of evaluating the different parameters included in the proposed expressions. The numerical values of these parameters agree with those of other authors and are theoretically discussed and justified.
