Researchers have demonstrated that Electron Cyclotron Resonance Heating (ECRH) can mitigate the generation of runaway electrons during plasma disruptions in the HL-3 tokamak. This finding is crucial for the development of nuclear fusion, as runaway electrons, high-energy particles that can severely damage reactor walls, represent one of the biggest challenges for the safe and efficient operation of future fusion devices like ITER. The ability to control these events is fundamental for the long-term viability of fusion energy.
