标题： ALICE Event Display -- from the legacy ROOT-based visualization to the web-based application

摘要： 大型离子对撞机实验（ALICE）是位于LHC的四个主要CERN实验之一。 研究的重点是研究夸克-胶子等离子体，这种等离子体是在重离子碰撞中产生的。 在线重构碰撞中产生的粒子轨迹，并与探测器几何结构一起可视化，以提供数据的适当增强。 这个交互式可视化工具允许从收集的数据中提取样本进行三维可视化。 从LHC运行3（2022年开始）起，采用了一种新的解决方案，这是在创建新的ALICE O\textsuperscript{2}框架之后。 第一步实现了数据处理部分。 可视化部分使用了LHC运行2的技术开发。 本文介绍了将可视化组件过渡到现代基于网络的解决方案的过程。 展示了现有的ALICE LHC运行3在线实时可视化解决方案的架构。 讨论了新方法的优势。 显示英文摘要

摘要： A Large Ion Collider Experiment (ALICE) is one of the four big CERN experiments at the LHC. The area of interest is the study of the Quark-Gluon Plasma which is produced in heavy-ion collisions. The trajectories of particles created in collisions are reconstructed online and are visualized together with the detector geometry to provide proper augmentation of the presented data. This interactive visualization tool allows 3D visualization of samples taken from the collected data. Starting with LHC Run 3 (from 2022), a newly developed solution has been adopted following the creation of the new ALICE O\textsuperscript{2} Framework. In the first step the data handling part was implemented. The visualization part was developed using technologies from LHC Run 2. This paper presents the process of transition of the visualization component to the modern web based solution. The architecture of the existing ALICE LHC Run 3 online real-time visualization solution is presented. The advantages of the new approach are discussed.
