US’ inverted D plasma research leads to breakthrough in nuclear fusion reactor control.

Scientists at the DIII-D National Fusion Facility are investigating a different approach to tokamak operation that has yielded promising results for the design of future fusion power plants.

Recent experiments have demonstrated that a plasma configuration known as “negative triangularity” can achieve the high-performance conditions necessary for sustained fusion energy, while also addressing a critical challenge related to heat management inside the reactor.
