A high-density and high-confinement tokamak plasma regime for fusion energy | Nature

Summary

This article explains an experimental advancement made in DIII-D tokamaks that demonstrates the potential for efficient fusion power. It addresses achieving high plasma density and confinement, sustained small ELMs, and moving toward divertor detachment—all essential for future fusion pilot plants (FPPs) like ITER. Key concepts include magnetic confinement, the high-confinement mode (H-mode), and the importance of the Greenwald density limit. The tags are well-aligned with the components and experiments mentioned, such as Tokamaks, Divertor, High-confinement mode, DIII-D, and ITER.
