In the second half of 2022, Startorus completed assembling the main body of SUNIST-2, a spherical tokamak. Its work on magnet-supporting pulsed power supplies also pressed forward smoothly. Such progress has prepared Startorus for verifying the viability of its fusion proposals and laid a solid foundation for the company to level the plasma performance of its device up to that of the world’s leading devices of the same size in the next stage.
