Development of Next-Generation Event Visualization Platform for the BM@N Experiment

Abstract

In high-energy physics experiments the ability to display both detector geometry and physical objects of particle collision events, such as hits and particle tracks has become an essential feature required for physicists to better understand particular collision events as well as to present the physical results to a wider audience. Currently, most experimental collaborations build their own event display solutions with little to no unification between them. In this work, a new event visualization solution for the BM@N (Baryonic Matter at Nuclotron) experiment, a fixed target experiment of the NICA (Nuclotron-based Ion Collider fAcility) project, is presented. The solution is based on VisionForge, a modern open-source visualization system. An important part of the solution is integration of the system with the experiment’s software framework, BmnRoot, which is a CERN ROOT-based environment. Several possible methods of such integration are discussed and the established architecture of the next-generation visualization system is explained.
