Researchers from the DIII-D National Fusion Facility are preparing to support their colleagues at the National Spherical Tokamak Experiment-Upgrade (NSTX-U) at the U.S Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) in a quest to develop sustained fusion energy. Under recently announced DOE funding programs, two teams at DIII-D will perform research on physics and instrumentation for NSTX-U as the facility’s staff work to restart operations late next year.

Feature

Scientists Solve Key Challenge for Controlling “Runaway” Electrons in Fusion Plasmas

July 16, 2020 sarah Jonas Fusion, fusion power, runaway electrons, tokamak

Scientists at the DIII-D National Fusion Facility have for the first time studied the internal structure and stability of high-energy runaway electron (RE) beams in a tokamak. The finding could provide a way to control the damaging potential of RE beams and could contribute to future power production using tokamak fusion power plants.
