Abstract

BM@N (Baryonic Matter at Nuclotron) is the first experiment to be realized at the NICA accelerator complex at JINR (Dubna). The aim of the experiment is to study interactions of relativistic heavy ion beams with a kinetic energy from 1 to 4.5 A GeV with fixed targets. In the paper an algorithm for global tracks reconstruction in the BM@N experiment is described. The core of the global track is the track inside the magnet, to which are added upstream and downstream tracks. The results of the proposed algorithm working for both the BM@N experiment and its extension SRC program are presented. Impact of global matching procedure on quality of reconstructed tracks is presented.

BM@N 实验中的全局跟踪

摘要

BM@N（Nuclotron 的重子物质）是在 JINR（杜布纳）的 NICA 加速器综合体实现的第一个实验。该实验的目的是研究具有 1 到 4.5 A GeV 动能的相对论重离子束与固定目标的相互作用。本文描述了BM@N实验中的全局轨迹重建算法。全局轨道的核心是磁体内部的轨道，其上添加了上游和下游轨道。给出了该算法在 BM@N 实验及其扩展 SRC 程序中的工作结果。介绍了全局匹配过程对重建轨迹质量的影响。
