Researchers have developed a deep learning framework to reconstruct detailed kinetic information about low-temperature plasmas from macroscopic measurements. By training neural networks like U-Net, Fourier Neural Operators (FNO), and MeshGraphNet on data from PIC-MCC simulations, the system can infer electron and ion energy distribution functions (EEDFs/IEDFs) from non-invasively measured plasma observables. The FNO model demonstrated the best performance, accurately recovering plasma density, temperature, and rate coefficients, which could advance plasma diagnostics and surrogate modeling. AI
