Japan -based Kyoto Fusioneering built a 1-megawatt gyrotron that can superheat plasma.

The device generates high-power microwave radiation required for heating and controlling plasma in fusion reactors.

Tokamak Energy plans to install the device on its spherical tokamak ST40 this year .

The company plans to use the technology to test lithium on the inner wall of the ST40 for a future fusion pilot plant.
