The DIII-D National Fusion Facility, located in San Diego, California, is the largest magnetic fusion research facility in the United States and is operated by General Atomics for the US Department of Energy. This facility plays an important role in optimizing the tokamak approach to fusion energy production since the mid-1980s and provides valuable data for the engineering design phase of ITER.
DIII-D has recently been in the news because has completed a two-year research campaign that resulted in a record-breaking 1,600 hours of plasma research and 140 groundbreaking studies, leading to many transformative advancements for delivering cost-effective fusion energy.
