描述了在L3+C实验的大型漂移室中基于组合Hough变换(CHT)的径迹寻找方法. 针对宇宙线事例中μ子方向近似平行的特点,从径迹段的方向的直方图可估算出事例的主方向,从而大大优化寻找完整径迹的Hough变换. 跨卦重建程序可高效率的重建多重度在50以下的宇宙线多μ事例.

We describe a track finding method based on the Combinatorial Hough Transform (CHT) in the large drift chambers of the L3+C experiment at CERN. With the feature of near parallelism of muons in cosmic multi-muon events, the dominant direction can be estimated from the histogram of directions of segments. Then the CHT in finding the whole track can be greatly optimized. The cross octant reconstruction program can efficiently reconstruct cosmic muon events with multiplicity up to 50.
