UK's Tokamak Energy reveals high-speed color details of plasma behavior

Breakthrough in Fusion Energy: Tokamak Energy Reveals Plasma Behavior

Tokamak Energy has released high-speed color images of plasma from inside a fusion energy machine, providing new visual insights into the behavior of the plasma.

Current experiments on our ST40 spherical tokamak are offering new visual insights into plasma behaviour, thanks to a high-speed colour camera capturing footage at 16,000 frames per second

The footage shows lithium turning greenish-yellow as it traces magnetic lines, clearly visualizing how the plasma is both fueled and controlled.
