Keeping it Cool while Maintaining Core Performance
One of the great challenges in fusion tokamaks is how to keep the core of a plasma hot enough that fusion can occur while maintaining a temperature at the edge of the plasma low enough that it doesn’t melt the tokamak’s walls. This requires dissipating the heat and particles flowing towards the wall without reducing the performance of the core. Researchers recently developed a pathway to addressing this core-edge integration challenge.
