Description
SIRIUS is a 4th generation synchrotron facility operated by LNLS/CNPEM, with multiple beamlines currently in operation and others under commissioning. As the number and complexity of beamlines grow, there is an increasing need for scalable, maintainable, and reusable software solutions.
To address these challenges, SIRIUS has been evolving its high-level control and orchestration ecosystem around modular services and a client-server architecture. A central component of this effort is the SIRIUS Ophyd and Bluesky Utilities (sophys) ecosystem, including sophys-server, sophys-clients (web, desktop and CLI) and beamline specific integration, which provide a unified way to execute experiments, manage queues, and interact with the experiment. It integrates data acquisition routines based on Bluesky, enabling a consistent interface across different beamlines. This approach has enabled code reuse, reduced maintenance overhead, and led to faster delivery of new features across multiple beamlines.
The architecture incorporates extensible authentication and authorization integrated with institutional systems. Additional applications such as sophys-CLI expand usability for different user profiles.
Recent developments include web-based real-time visualization of control system process variables and support for asynchronous acquisition modes such as fly-scanning. Ongoing work also explores solutions for more complex experimental scenarios, including multiple concurrent execution queues for parallel and in situ experiments.
Looking forward, we discuss the adoption of Tiled as a potential layer for structured data access and experiment planning, and its integration with workflow orchestration tools such as Prefect. These directions aim to further improve reproducibility, automation and interoperability across beamlines and to provide the flexibility needed to reach a better user experience and more efficient use of beamtime.
