General Fusion says its LM26 fusion machine has more than tripled plasma electron temperature through mechanical compression alone, reaching about 0.72 keV, or 8.4 million degrees Celsius.
The Vancouver-based company said the result marks a key step for its Magnetized Target Fusion (MTF) technology, which aims to generate fusion conditions by compressing plasma rather than relying on powerful lasers or massive superconducting magnets.
According to the company, LM26 achieved a more than threefold increase in electron temperature during compression, bringing it closer to its next target of 1 keV, equivalent to roughly 10 million degrees Celsius.
The findings have been submitted for peer review. General Fusion said the results were obtained using its Lawson Machine 26, a large-scale demonstration system that has been operating since 2025.
