PPPL physicist Fatima Ebrahimi has for the first time used advanced models to accurately simulate key characteristics of the cyclic behavior of edge-localized modes, a particular type of plasma instability. The findings could help physicists more fully comprehend the behavior of plasma, the hot, charged gas that fuels fusion reactions in doughnut-shaped fusion facilities called tokamaks, and more reliably produce plasmas for fusion reactions.
