Physics-Informed Neural Networks Infer Plasma Conductivity in Stellarators

By PulseAugur Editorial · [1 sources] ·

Researchers have developed a novel framework using Physics-Informed Neural Networks (PINNs) to infer the perpendicular energy conductivity in the scrape-off layer of stellarator devices. This method combines plasma profile measurements with a reduced transport equation to constrain the inferred conductivity, $\kappa_\perp(n,T)$. The framework was validated with synthetic data, achieving less than 10% error, and has been applied to experimental data from the TJ-II stellarator, providing an initial estimate of the effective SOL conductivity.
