随着高能物理软件不断发展和物理分析对软件日益增长的需求，开发通用高效的模块化软件成为高能物理的发展趋势。带电径迹重建是高能物理数据处理环节最重要的部分，重建算法的好坏直接影响物理分析的精度。环形正负电子对撞机CEPC当前有多种探测器设计布局，每种几何设计布局需要开发相应的重建算法，因此我们希望引入一个完整的通用径迹重建框架(ACTS)，在该框架下可以实现每种探测器布局的径迹重建和算法优化，进而在重建性能角度对不同的探测器设计方案进行评估，从而达到优化CEPC探测器设计的目的。

With the development of the high energy physics software, and the growing demand from the physics analysis, the project of developing general and efficient modelized software becomes the trend. Charged track reconstruction is the most essential task in the processing of high energy physics data analysis, which directly impacts on the accuracy of physics results. There exists various designs of The Circular Electron Positron Collider (CEPC) detector layouts, while each of them requires a corresponding reconstruction algorithm. Therefore, we hope to introduce a common tracking software (ACTS), by which we can implement the whole reconstruction steps and carry out the optimization for all the detector layout designs. We will finally give an evaluation of the different detector layouts in terms of the reconstruction performance, to optimize the design of the CEPC detector.
