Description
A multifaceted virtual accelerator model that seamlessly integrates with the online experimental system would highly benefit the operators to test and evaluate beam tuning scenarios and apply them online. As part of this effort, the beam dynamics code TRACK is wrapped with control system architecture and the graphic user interface BADGER developed by SLAC. Customizability and task visualization are prioritized based on end user feedback. More important than the user experience is how well the simulation model agrees with the experimental measurements. A recent effort to account for beam steering and misalignment effects has reduced the error between simulation and measurements from ~ 40% to ~ 10%. More work to pare down this error and close the gap even further is currently underway. The concurrent execution of simulation with experiment for troubleshooting and parallel simulation-based optimizations to quickly determine ideal element settings that map to desired beam parameters are some of the features to be highlighted. Previously published AI/ML capabilities are incorporated to this extent. Surrogate models based on collected data to reproduce a given set of operating conditions (beam energy, charge state etc.) and use of an LLM to monitor simulation progress and make informed decisions at a higher level will be included as add-on features.
