Spinning Plasma Solves a Long-Standing Fusion Reactor Mystery

A persistent asymmetry in fusion exhaust has challenged researchers for years. New simulations show that plasma core rotation, working together with cross-field drifts, determines where particles land inside a tokamak. Tokamaks are often described as giant magnetic “doughnuts,” built to keep an ultra-hot soup of charged particles suspended long enough for atomic nuclei to fuse […] Read More
