Information System Based on the Condition Database for the NICA Experiments, User WEB Application, and Related Services

Abstract

The NICA collider complex currently under construction at the Joint Institute for Nuclear Research in Dubna is aimed at creating and investigating hot baryonic matter under extreme conditions. During offline and even online data processing, a large set of various parameters of experiment systems and conditions, under which the experiments are conducted, are required for experimental event reconstruction, detector simulation, physics analysis and quality assurance. To solve the task of storing the required parameters and information on the NICA experiments, which are necessary for further processing of the obtained experimental data (as well as simulated events), an information system has been developed on the basis of the condition database. For convenient management of the data stored in the database called Unified Database, a web application has been implemented for viewing, searching, managing and visualizing information on the experiments of the NICA project, such as information on sessions and runs, detectors, parameters and parameter values, and, in addition, generated simulation files. Furthermore, the developed information system provides collaboration members with a set of auxiliary services, such as data inspection and monitoring services, which improve the functionality of the system and make it more convenient. The paper presents the information system and its components including the condition database, user interfaces and web application, and implemented related services.
