Abstract

The article is dedicated to the current state of the Geometry Database for the BM@N experiment of the NICA project. The main goal of the database is to provide a central storage of the BM@N geometries, convenient tools for managing its geometry modules, various software assembling versions of the BM@N setup as a combination of modules and additional files providing support for a set of versions. Both the Graphical User Interface (GUI) and the Application Programming Interface (API) have been developed.

Summary

Introduction

The rich heavy-ion physics program will be performed at two experiments: BM@N (Baryonic Matter at Nuclotron) at beams extracted from the Nuclotron and MPD (MultiPurpose Detector) at the NICA collider [1]. BM@N [2] is a fixed target experiment being the first one of the NICA megaproject. The experimental setup was installed in the fixed-target hall, where particle beams from the Nuclotron are extracted, to perform the research program focused on the production of strange matter in heavy-ion collisions at beam energies from 2 to 6 AGeV. The BM@N experiment was started in 2015, and a set of technical runs was performed with deuteron, carbon, argon and krypton beams collided with various targets, from polyethylene to lead. The upgrade of the experiment entails upgrades of the software systems including the software that describes the BM@N geometry
