Abstract
Two types of wedge-shaped CsI(Tl) crystals were designed to be placed behind an annular double-sided silicon detector to identify light charged-particles with the ΔE−E method. The properties of the CsI(Tl) detectors with different shapes and sizes were investigated using an α source and a radioactive beam of 15C. The larger crystal was found to have better energy resolution, smaller light output non-uniformity, as well as better particle identification capability, and was finally adopted to form the ΔE-E telescope. The performance of the two types of CsI(Tl) crystals are interpreted based on Geant4 simulation results.
