Abstract

A requirement to collect light from large area scintillators lead to wave length shifting (WLS) technique based on the following principle. Light produced by ionising particle in a scintillator plate after some internal reflections exits the scintillator and hits a WLS bar. Inside the bar the blue light of the scintillator is re-emitted isotropically into longer wave length. Part of the light which lies within angles of internal reflection is trapped. For a polystyrene bar the trapping efficiency is 20–30% (in both directions).
