以L3宇宙线实验的径迹重建为例,讨论了一个在磁谱仪漂移室中对大斜率宇宙线径迹着火点进行重建的Cellmap,并与L3宇宙线实验中已采用的Cellmap进行了比较.对大斜率径迹,用新的Cellmap可以重建出更多的着火点,并且径迹重建χ2量的分布有所改善.
Taking the track reconstruction of L3 cosmic ray experiment as an example, we discuss a Cellmap that reconstructs the large-slope cosmic ray trace fire point in the drift chamber of the magnetic spectrometer and compares it with the Cellmap that has been used in the L3 cosmic ray experiment. For large-slope tracks, more new fire spots can be reconstructed with the new Cellmap, and the distribution of track-corrected χ2 is improved.
