通过分析用 GEANT产生的 1 0 0个事例样本 ,确立了判选光子所产生的 Com pton电子径迹的第一和第二顶点的一种方法。基于此方法 ,可以很好地对 L Ar- TPC中产生 Compton电子的 6 .1 3Me V光子的动量和方向完成重建。
【英文摘要】
We found a selection method of the 1st and 2nd verfer of Compton electron track after analysing 100 event sample which is generated by GEANT.Based on this method the momentum and direction of 6.13 MeV Gamma photons which creat Compton electrons in LAr TPC can be reconstructed very well.The comparison with experimental data is in progress.
