位于欧洲核子研究中心的阿尔法实验旨在比较反氢原子与氢原子的性质。中性反氢原子被八极磁阱捕获。陷阱区周围是一个三层硅探测器，用于重建反质子湮灭顶点。本文介绍了一种方法，我们设计的，可以用于重建湮没顶点具有良好的分辨率，是更有效的比目前用于相同目的的标准方法。
The ALPHA experiment, located at CERN, aims to compare the properties of antihydrogen atoms with those of hydrogen atoms. The neutral antihydrogen atoms are trapped using an octupole magnetic trap. The trap region is surrounded by a three layered silicon detector used to reconstruct the antiproton annihilation vertices. This paper describes a method we have devised that can be used for reconstructing annihilation vertices with a good resolution and is more efficient than the standard method currently used for the same purpose.
