Descripción
The detection of heavy ions and light particles in inorganic scintillators has been recently implemented in fragmentation facilities for measurements of beta decay and charged particle emission. One of the challenges of using scintillators in these experiments is the need to simultaneously detect energetic ions, which deposit GeV energy, and subsequent decays, which can deposit less than 1 MeV. Detection of signals with such a wide dynamic range in scintillator material is only possible due to light quenching, which drastically reduces the scintillator’s light output for heavy ions. This effect has been studied experimentally, and a parametrization of this effect based on the models of Birks [1,2] and others [3] was proposed. Following these approaches, we developed a method to predict light quenching for various combinations of heavy ions and scintillator materials based on recent experimental measurement. This method can be used to plan fragmentation experiments in different energy regimes. I will present the findings from our model and compare them with the experimental results.
