Tech News 1: Blowing dust to cool fusion plasmas

[bob_turner]

Future tokamak fusion power reactors will generate heat beyond what current materials can withstand. Scientists have proposed various methods for cooling the edge of the magnetically confined fusion fuel, or plasma, to protect the walls of the surrounding tokamak. One approach is injecting impurities in the form of gases to help radiate away excess heat. However, there is a limited range of gases that can be injected, and some gases react poorly with hydrogen fusion fuel.
