          Abstract

          This paper describes the requirements and implementation of the Traceability System at Sirius, the Brazilian synchrotron light source. The system was designed to ensure that only personnel trained by the Radiation Protection Group operate the beamlines. The solution utilizes radio-frequency identification technology to enable the "Search" procedure, a mandatory safety step for the release of synchrotron radiation. The system integrates Siemens programmable logic controllers (PLCs), C# development for data encoding, and a web infrastructure based on MariaDB, Node-RED, and PHP for real-time monitoring. Results indicate that, between June 15, 2023 and October 24, 2025, 34,099 search procedures were performed across the 15 beamlines in operation and commissioning, involving more than 200 internal and external users. This work elucidates the system's technical architecture and demonstrates its effectiveness in radiological safety management and the traceability of experimental activities at Sirius.
