Scintillators for photon detection at medium energies—a comparative study of BaF2, CeF3 and PbWO4

Abstract In a comparative study, the performance of sub-arrays consisting of large CeF 3 and PbWO 4 crystals has been investigated with high-energy photons below 1 GeV. Energy and time resolutions are determined and compared with the corresponding values for BaF 2 based on the experience of operating the electromagnetic calorimeter Taps .
