Description

Digital shadows offer a methodology for bridging physical particle accelerators with their virtual counterparts, enabling predictive modelling, automated control, and improvements in facility design and implementation. A digital shadow for the CLARA accelerator is being developed, integrating two complementary tools: LAURA, an ontology-driven description language for particle accelerator lattices; and SIMBA, a simulation framework that utilises LAURA-defined models to perform start-to-end particle tracking using multiple tracking codes. Together, LAURA and SIMBA form the simulation backbone of a digital shadow, providing a consistent and extensible representation of the accelerator. This architecture is further augmented by pyCATAP, a controls middle layer that interfaces with accelerator control systems, PUMBA, a procedural automation framework for running complex operational tasks and standardising I/O data structures, and SARABI, a framework for generating soft EPICS IOCs from a LAURA lattice.
