After nearly five years of fabrication and a battery of rigorous testing and troubleshooting, General Atomics (GA) has completed the first major milestone in one of the United States’ largest contributions to the ITER fusion project in France. The first module of the ITER Central Solenoid will join six others still in fabrication to make up the largest pulsed superconducting magnet in the world. The Central Solenoid will play a critical role in ITER’s mission to establish fusion as a practical, safe and nearly inexhaustible source of clean, abundant and carbon-free electricity.

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.

Researchers at the DIII-D National Fusion Facility recently achieved a scientific first when they used machine learning calculations to automatically prevent fusion plasma disruptions in real time, while simultaneously optimizing the plasma for peak performance. The new experiments are the first of what they expect to be a wave of research in which machine learning–augmented controls could broaden the understanding of fusion plasmas. The work may help deliver reliable, peak-performance operation of future fusion reactors.
