研究了AMS02电磁量能器簇射三维重建,发展出一个新的三维重建程序,并用蒙特卡罗模拟以及2002年束流测试数据对其进行了检验.该程序应用两次方向重建、结合光纤衰减修正、横向以及纵向能量泄漏补偿,完整地对事例进行了重建,得到了较为理想的能量分辨率和角度分辨率。
A new program of 3D-reconstruction of AMS02 Electromagnetic Calorimeter(ECAL) is developed. In the program, the direction reconstruction is iterated, and the corrections for fiber attenuation, transverse leakage and longitudinal leakage are performed. The program is tested by comparing the beam test data and Monte-Carlo simulation, and a good agreement is obtained.
