考虑到北京谱仪扩建后现有内漂移室（IDC）的老化效应，提出了一种基于GEM的内跟踪器作为IDC的升级候选方案。本文介绍了一个简化数字化模型的CGEM-IT全模拟软件包，描述了CGEM-IT中基于Kalman滤波方法的团簇重建和径迹拟合算法的软件开发，并利用CGEM-IT中的单μ子事例的Monte Carlo样本，给出了重建算法的初步结果。
Considering the aging effects of existing Inner Drift Chamber (IDC) of BES\uppercase\expandafter{\romannumeral3}, a GEM based inner tracker is proposed to be designed and constructed as an upgrade candidate for IDC. This paper introduces a full simulation package of CGEM-IT with a simplified digitization model, describes the development of the softwares for cluster reconstruction and track fitting algorithm based on Kalman filter method for CGEM-IT. Preliminary results from the reconstruction algorithms are obtained using a Monte Carlo sample of single muon events in CGEM-IT.
