Upgrading the ATLAS tune archiving system

The Argonne Tandem Linear Accelerating System (ATLAS) facility at Argonne National Laboratory is a National User Facility capable of delivering ion beams from hydrogen to uranium. The existing tune archiving system, which utilizes Corel’s Paradox relational data-base management software, is responsible for retrieving and restoring machine parameters from previously optimized configurations. However, the Paradox platform suffers from outdated support, a proprietary programming language, and limited functionality, prompting the need for a modern replacement. To address these limitations, ATLAS is transitioning to a new archiving system based on PySide for the user interface, InfluxDB for time-series data storage, and FastAPI for backend communication.
