Fusion energy: Progress, partnerships, and the path to deployment
Over the past decade, fusion energy has moved decisively from scientific aspiration toward a credible pathway to a new energy technology. Thanks to long-term federal support, we have significantly advanced our fundamental understanding of plasma physics—the behavior of the superheated gases at the heart of fusion devices. This knowledge will enable the creation and control of fusion fuel under conditions required for future power plants. Our progress is exemplified by breakthroughs at the National Ignition Facility and the Joint European Torus.

Plasma flow velocity and its shear perpendicular to magnetic-field lines are generated by using the tungsten hot plate concentrically three segmented, which can form the radially-different plasma potential, or radial electric field even in a fully-ionized collisionless plasma. A drift-like instability which exists in the peripheral region, where the density gradient is relatively large, is observed to be suppressed by the perpendicular flow velocity shear in the central region.
