摘要：

The behaviour of plastic scintillator bars with length up to 450 cm, designed for the CLAS large angle electromagnetic shower calorimeter, is considered in relation to the overall calorimeter response function. In particular methods adopted to measure the light emission yield and transmission efficiency are described and the influence of the scintillator bar properties on the calorimeter energy read-out and timing is discussed. We found that the new scintillator NE110A manufactured by NE Technology Ltd. showed the best agreement with our demands. The effect of wrapping materials on the scintillator bar properties has been studied considering also the temperature variations expected in Hall B at CEBAF.
