摘要
本文介绍在前冲谱仪中重建带电粒子径迹的一种三维约束方法。用最小二乘法求解X^2方程,得出满足X^2为最小值时的径迹参数。为了减少计算时间,用二维x线作为计算出发点。用蒙特卡罗数据对本方法进行了检验,并与其它方法所得的结果进行了比较。结果说明这一方法的分辨率和正确性均较好。
A new three dimensional constrained method to reconstruct the charged particle tracks for the forward spectrometers is introduced. Using the method of least squares to solve the equation, the parameters of the tracks can be obtained. In order to reduce the computing time, the two-dimensional x-line is used as the starting points. We generated some Monte-Carlo data and compare the results with the data by different methods. It is shown that this method has good resolution and accuracy.
