General Fusion Achieves World-First 1 keV Electron Temperature Milestone on its Path to Commercial Fusion Power

October 8, 2026 8:00 AM EDT

1 keV result announced jointly with the UKAEA and accompanied by meaningful ion heating

VANCOUVER, British Columbia, Oct. 08, 2026 (GLOBE NEWSWIRE) -- General Fusion Group Ltd. (NASDAQ: GFUZ) ("General Fusion" or the "Company") has achieved a world-first compressional plasma heating result with its large-scale Lawson Machine 26 ("LM26") demonstration, a key milestone on its path to commercialize fusion energy. Using Magnetized Target Fusion ("MTF"), the Company has reached electron temperatures exceeding 12 million degrees Celsius, more than 1 keV, measured with both Thomson scattering and absolute extreme ultraviolet ("AXUV") diagnostics, and accompanied by meaningful ion...
