Abstract

In this paper, the results of accelerated heat-ageing tests of the tellurium-loaded plastic scintillator are introduced. The dependence of light yield on temperature is discussed. The lifetime of polystyrene-based plastic scintillator has been evaluated to be – 3.8 ± 0.2syst ± 0.1stat and 7.6 ± 0.4syst ± 0.1stat years under normal conditions according to the change in the light yield by 10 or 20% of the initial value of the parameter.
