SUMMARY:
In-Situ Visualization and Steering of Digital Twins for Particle 
 Accelerators
DESCRIPTION:Andreas Adelmann (Paul Scherrer Institute PSI)\n\nDigital twin
 s are emerging as a transformative concept for the design, operation, and 
 optimisation of complex scientific instruments. In this plenary, I will pr
 esent recent progress on integrating in-situ visualization and interactive
  steering into the open-source accelerator simulation framework OPAL. The 
 motivation is rooted in the way modern particle accelerators are operated—
 where real-time monitoring, adaptive decision-making, and iterative optimi
 sation are indispensable.

By coupling high-fidelity simulations with in-s
 itu analysis and steering, we demonstrate a new paradigm: optimisation dur
 ing simulation. This approach reduces turnaround time, enables exploration
  of vast parameter spaces, and creates opportunities for interactive workf
 lows that mirror experimental practice. Beyond accelerator science, these 
 developments resonate strongly with other domains that rely on large-scale
  digital twins, such as fusion energy, materials science, and climate mode
 lling.

I will discuss the architectural and HPC challenges of enabling su
 ch capabilities, including integration with exascale systems, data movemen
 t constraints, and scalability considerations. I will conclude with a pers
 pective on how in-situ visualization and steering can reshape scientific c
 omputing more broadly, supporting interactive, real-time science at unprec
 edented scales.⁦\n\nRecording: Not Livestreamed, Not Recorded, Partially L
