RICHMOND, British Columbia, Nov. 22, 2024 — General Fusion has made significant strides in the field of fusion energy, achieving world-first results in plasma compression using its Magnetized Target Fusion (MTF) technology. The findings, published in the journal Nuclear Fusion, confirm that the company successfully produced a substantial fusion neutron yield during its Plasma Compression Science (PCS) experiment series.
The innovative experiments demonstrated a method that maintains plasma stability and symmetry during compression, validating the company's predictions regarding plasma heating rates and neutron yield increases. This research lays the groundwork for the Lawson Machine 26 (LM26), a large-scale fusion demonstration set to begin operations in early 2025.
LM26 aims to achieve pivotal milestones, targeting temperatures of 1 keV and 10 keV, which correspond to fusion conditions exceeding 100 million degrees Celsius. Ultimately, the project aspires to reach scientific breakeven equivalent, fulfilling the 100% Lawson criterion within the next two years.
Key outcomes from the PCS experiments include a neutron yield surpassing 600 million neutrons per second in a single compression shot, with plasma density increasing approximately 190 times its initial state. The magnetic field used for plasma confinement was found to be over 13 times stronger during compression, enhancing the stability of the high-energy environment.
Dr. Michel Laberge, Founder and Chief Science Officer of General Fusion, stated, "This research exemplifies our pioneering efforts over the past two decades. We are now on the verge of achieving breakthrough milestones with LM26, which could lead to economical power generation by the early to mid-2030s."
General Fusion's approach to MTF utilizes a liquid metal liner mechanically compressed by high-powered pistons, allowing for the creation of fusion conditions in short pulses. This method not only protects the machine's vessel but also facilitates heat extraction and fuel re-breeding, positioning the technology as a viable option for cost-effective power plants.
The advancements in plasma compression technology signify a promising step toward commercial fusion energy, with the potential to transform global energy landscapes and contribute to sustainable power solutions.
