Abstract: A high-resolution gamma-ray detector consisting of an 8mm diameter and 5mm thick LaCl3(Ce3+) scintillation crystal coupled to a 16mm diameter APD from Advanced Photonix Inc is presented. The energy resolution R obtained at 662keV is about 3.7% (full-width at half maximum). The low intrinsic resolution of about 2%, the high light yield of the crystal (460005000 photons per MeV) and the high quantum efficiency of the avalanche photodiode make this gamma-ray detector an excellent choice for applications were a high energy resolution is required.
