The Measurement of the Performance of L3 Hadron Calorimeter With BGO

本文介绍了配有BGO(锗酸铋)晶体阵列的L3铀强子量能器性能的模拟测试。对L3强子量能器以及测试实验作了简要介绍,并给出了该量能器对4—20GeV能量范围的π介子的能量分辨率、e/π响应比、角分辨、能量分辨率随入射π介子方向的变化以及强子穿透率等实验结果。

The four L3 hadron calorimeter modules with BGO have been tested with pion beams of energies between 4 and 20 GeV. L3 calorimeter, the gas sampling Uranium module and its test with beam are bricfly described. The energy resolution for pions with energies between 4 and 20 GeV were measured. The e/pion ratio, angular resolution, dependence of the energy resolution on the direction of incident pions, hadron punch through and track through also were measured and analyzed.
