Too hot to handle? Nuclear fusion breakthrough tames scorching plasma inside tokamaks

Swiss scientists have developed a new method to remove excess heat from tokamak fusion reactors, improving safety during high-temperature operation. The technique, called X-point target radiator, adds a second X-point along the divertor funnel to boost heat-removing radiation without damaging the reactor walls.

This breakthrough at the Variable Configuration Tokamak could potentially be implemented in next-generation reactors like SPARC. It allows for better control of plasma conditions and opens up new possibilities for managing power exhaust in fusion reactors.
