本文提出了一种GEM探测器中入射离子的快速顶点重构方法。受时间投影室（TPC）方法的启发，利用来自前端电子设备（FEE）的连续信号样本的时间信息。该方法是证明与2D读出THGEM探测器与APV-25 FEE耦合。在分析中仅使用一个实验相关参数，所提出的方法导致0.45 mm的空间分辨率，相比之下，传统的重心方法的值为9.10 mm。
This work proposes a fast method of vertex reconstructing for incident ions in GEM detectors. Inspired by the Time Projection Chambers (TPC) approach, the time information of consecutive signal samples from Front End Electronics (FEE) is utilized. The method is demonstrated with a 2D-readout THGEM detector coupled with an APV-25 FEE . Using only one experimentally dependent parameter in the analysis, the proposed method resulted in a spatial resolution of 0.45 mm, compared to a value of 9.10 mm for the traditional center of gravity method.
