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 heating. This world-first result for General Fusion's practical approach to fusion marks a major step forward on the Company's plan to deliver reliable baseload, economical clean power from fusion energy.
The gold-standard Thomson scattering result, measured in collaboration with the UK Atomic Energy Authority ("UKAEA"), is detailed in a joint release issued today by the two organizations and a technical paper co-authored by UKAEA that is being concurrently posted on General Fusion's website and submitted for peer review. The Company's AXUV temperature measurement and ion heating results are detailed in a separate technical paper, also available on General Fusion's website and submitted for peer review.
The combined results provide further confidence in the Company's core MTF technology principles and achieve the first of three key technical milestones for LM26.
The combined results provide further confidence in the Company's core MTF technology principles and achieve the first of three key technical milestones for LM26. Its next major milestone on its path to commercial power: compressional heating to 10 keV. Planned upgrades to LM26 are now underway for this next milestone.
