Harnessing Simulation to Unlock Fusion
At First Light Fusion, simulation lies at the heart of our research programme.
Realising Inertial Fusion Energy (IFE) requires the design of extraordinarily complex physical systems. Yet, the data available to inform these designs is scarce, as both large-scale computer simulations and real-world experiments come at significant cost. Success depends on our ability to accurately and quickly model extreme physical phenomena, from plasma dynamics to high-velocity impacts, long before a physical test can be run.
By building powerful and precise simulation frameworks, we can explore design space efficiently, test hypotheses safely, and reduce uncertainty before committing to costly experiments. Simulation provides the foundation upon which all further innovation is built.
Augmenting Simulation with Probabilistic AI
To extend the reach of these simulations, we leverage cutting-edge methods in probabilistic artificial intelligence (AI). These bespoke models accelerate design cycles by rapidly predicting how new amplifier concepts will perform in fusion conditions - in a fraction of a second and at a fraction of the cost of running full simulations.
Probabilistic AI refers to systems that use probability theory to reason and make decisions under uncertainty. Instead of returning a single, fixed output, these models provide probability distributions over possible outcomes, reflecting the inherent complexity of the real world. This enables better experimental decision-making when data is noisy, incomplete, or ambiguous. Crucially, these models evolve continuously, updating their predictions as new results are generated.
Constantly Evolving
Together, simulation and AI support every stage of our fusion research and development process - from optimising the design of fusion targets and power-plant concepts, to modelling plasma behaviour and interpreting experimental outcomes. By feeding new data back into our frameworks, our models steadily gain accuracy and predictive power over time.
Our teams combine the most sophisticated methods in simulation and AI to calibrate, reduce uncertainty, and accelerate the refinement of experimental setups. This integrated approach reduces risks at every stage of research, driving us ever closer to achieving commercial fusion energy.
