PPPL Unravels Puzzle to Speed Development of Fusion Energy
Princeton Plasma Physics Laboratory, John Greenwald, December 17, 2021
A computational technique developed by researchers at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL) can model the movement of free electrons during fusion-harnessing experiments. The algorithm would simulate pitch-angle scattering without losing the energy of the speeding electrons. PPPL's Yichen Fu said, "By solving the trajectories we can know the probability of electrons choosing every path, and knowing that enables more accurate simulations that can lead to better control of the plasma." PPPL's Hong Qin said the research findings offer a strong mathematical proof of the first working algorithm for solving the equation.
