摘要
利用GEANT4软件包模拟了BESIII TOF模型束流实验,模拟结果和实验结果进行了比较,并解释了ESR膜作包装材料比用铝膜作包装时间分辨反而差的现象,以及5cm厚的闪烁体比4cm和6cm厚的闪烁体时间分辨好的实验结果。
Based on GEANT4, a simulation study of the BESIII TOF test-beam has been done. The simulation result and the test-beam result are compared. The simulation result can be used to explain that why the time resolution is better when the scintillator wrapped by ESR than wrapped by Al Im. And it also explained that the 5cm thickness scintillator has the better time resolution than 4cm and 6cm thickness scintillator.
