Exploring the Science of Plasma Physics on DIII-D National Fusion Facility

DIII-D is a premier plasma research facility dedicated to advancing the science of plasma behavior, improving stability, and managing hot plasmas. A core principle of the DIII-D program is the belief that developing fusion energy solutions requires a deep scientific understanding. To this end, DIII-D is equipped with an extensive array of plasma diagnostics, enabling detailed studies of plasma mechanisms and behaviors. This effort is bolstered by collaboration with numerous universities and national laboratories, which contribute diverse expertise and innovative ideas.

A significant initiative within DIII-D is its engagement with discovery plasma science, which began in 2016. This initiative has significantly enhanced understanding of the fundamental physics shared between fusion plasma science and fields such as magnetosphere, solar physics, astrophysics, and low-temperature plasmas. Key areas of study include magnetic reconnection, wave-particle interactions, plasma-material interactions, and turbulence.

DIII-D is currently undergoing a series of upgrades aimed at further advancing scientific understanding. Additionally, improvements to plasma diagnostics will support these upgrades, providing more comprehensive data on plasma behavior.
