μ子电离冷却实验（MICE）将演示通过电离冷却减少μ子束相空间的原理。拟建的中微子工厂或μ子对撞机将需要μ子束冷却。必须精确测量冷却单元前后的相空间。这是使用两个光纤跟踪器实现的，每个光纤跟踪器都放置在螺线管磁场中。本文介绍了软件重建的光纤跟踪器：GEANT 4为基础的模拟;实施的几何形状;数字化;空间点重建;模式识别;和最后的跟踪拟合卡尔曼滤波器的基础上。软件的性能进行评估，通过蒙特卡罗研究和最终的轨道重建的精度进行评估。
The Muon Ionization Cooling Experiment (MICE) will demonstrate the principle of muon beam phase-space reduction via ionization cooling. Muon beam cooling will be required for the proposed Neutrino Factory or Muon Collider. The phase-space before and after the cooling cell must be measured precisely. This is achieved using two scintillating-fibre trackers, each placed in a solenoidal magnetic field. This paper describes the software reconstruction for the fibre trackers: the GEANT4 based simulation; the implementation of the geometry; digitisation; space-point reconstruction; pattern recognition; and the final track fit based on a Kalman filter. The performance of the software is evaluated by means of Monte Carlo studies and the precision of the final track reconstruction is evaluated.
