文摘
The Pre-Shower detector was built for the high acceptance di-electron spectrometer to identify electrons produced in pion, proton and heavy ion-induced reactions in the 0.2<p<1.5GeV/c momentum range. The system is composed of three layers of wire chambers interleaved with two layers of lead converters for electromagnetic shower formation. A scintillator wall is placed in front of the detector for time-of-flight measurements.
