Monte Carlo study of light transport in scintillating fibers

A Monte Carlo model is developed which simulates the light transport in a scintillator surrounded by a transparent layer with different surface properties. The model is applied to analyse qualitatively the light collection properties of scintillating fibers. The influence of the characteristics of the fiber interfaces (core—cladding and cladding—air) as well as of the fiber end surface on the light yield is investigated in detail.
