Research scientist from MIT, Nathan Howard has won the 2019 Nuclear Fusion Award from the International Atomic Energy Agency (IAEA) for explaining the heat loss due to a disturbance in the core of magnetically confined fusion plasmas. Howard figured out that only by performing multiscale simulations he could match the experimental observations. The multiscale results of Howard’s paper have been combined into a reduced transport model called Trapped Gyro-Landau Fluid (TGLF), a model that provides results faster than a supercomputer. Howard thanks his program managers at the Department of Energy for significant support and encouragement.
