SUMMARY:"Multi-fidelity digital models for fusion energy device optimi
 zation\, design\, and operation"\, Plasma Physics (Physics/ECE/NE 922)
  Seminar\, Michael Churchill\, Princeton Plasma Physics Laboratory
DESCRIPTION:Digital modelling of the physics and engineering of next-s
 tep fusion devices will become increasingly important for their succes
 sful design and operation. A classical divide exists between modeling 
 relying on pure simulation and pure experimental scaling laws (the so-
 called “sim2real” gap). High-fidelity modeling can help to close t
 his gap\, but often does not fulfill the speed needed for certain work
 flows such as design optimization and control room analysis. I will pr
 esent several efforts and techniques including AI/ML and advanced opti
 mization being pursued towards building out faithful digital twins\, b
 ased on a range of simulations covering differing physics and levels o
 f fidelity. Examples will range from stellarator design optimization w
 ith the StellFoundry SciDAC collaboration\, to fast simulation-based i
 nference with experimental diagnostics.
