The performance of an electromagnetic calorimeter with lead-tungstate (PWO) crystals was tested by using 1 GeV photons. The calorimeter consisted of nine crystals of 20×20×200 mm in size arranged in a 3×3 array. The energy resolution was obtained to be σ_E/E=(2.50±0.75%) /√【○!+】(1.25±0.34%) with a photomultiplier tube (PMT) reading all signals. Another setup, reading the central cell with an avalanche photo diode (APD) and the surrounding 8 cells with the PMT, was also studied, however, its energy resolution was not scaled with the stochastic function and we found the resolution of about 10% around 1 GeV. |
