arXiv:2509.05510v3 Announce Type: replace-cross Abstract: Continued progress in inertial confinement fusion (ICF) requires solving inverse problems relating experimental observations to simulation input parameters, followed by design optimization. However, such high-dimensional dynamic PDE-constrained optimization problems are extremely challenging or even intractable. It has been recently shown that inverse problems can be solved by only considering certain robust features. Here we consider the ICF capsule's deuterium-tritium (DT) interface, and construct a causal, dynamic, multifidelity redu
The continuous advancements in AI, particularly in machine learning and causal inference, are enabling new approaches to complex scientific problems like ICF, previously intractable with traditional methods.
This development suggests AI can significantly accelerate fusion energy research by making the design and optimization of implosions more efficient and less resource-intensive, potentially bringing commercially viable fusion closer.
The ability to use multi-fidelity surrogate models for forward and inverse problems in ICF means the discovery and calibration of optimal parameters for fusion will become significantly faster and more accurate, reducing the need for costly physical experiments.
