General Fusion says LM26 hit 1.1 keV electrons in paper under peer review
General Fusion said on October 8, 2026 that its LM26 machine heated plasma electrons to 1,090 ± 40 eV (about 1.1 keV), a Thomson scattering measurement in a paper co-written with UKAEA and submitted for peer review. A companion paper reports 1,180 eV from X-ray diodes; the company targets 10 keV next and all three LM26 milestones by 2028.
UK Fusion Week: a UK-US statement, a supercomputer link and up to £3m
The Global Fusion Policy Summit in London on September 14, 2026 is first on the Fusion Industry Association's listing for UK Fusion Week, which runs to September 17. The UK and US issued a joint statement saying fusion safety standards should be distinct from fission safety standards; UKAEA and PPPL signed a declaration of intent to explore linking the SUNRISE and STELLAR-AI supercomputers; Tennessee, TVA and the UK expanded a fusion partnership; Kyoto Fusioneering committed up to £3 million to a breeder blanket experiment for STEP; and DESNZ published a fusion regulation landscape paper.
