Peer-reviewed publication confirms General Fusion achieved plasma energy confinement time required for its LM26 large-scale fusion machine

Nuclear Fusionconfirm General Fusion successfully created magnetized plasmas that achieved energy confinement times exceeding 10 milliseconds. The published energy confinement time results were achieved on General Fusion's PI3 plasma injector—the world's largest and most powerful plasma injector of its kind.

Nuclear Fusion confirm General Fusion successfully created magnetized plasmas that achieved energy confinement times exceeding 10 milliseconds. The published energy confinement time results were achieved on General Fusion's PI3 plasma injector—the world's largest and most powerful plasma injector of its kind. Commissioned in 2017, PI3 formed approximately 20,000 plasmas in a machine of 50 per cent commercial scale. The plasma injector is now integrated into General Fusion's Lawson Machine 26 (LM26)—a world-first Magnetized Target Fusion demonstration tracking toward game-changing technical milestones that will advance the company's ultimate mission: generating zero-carbon fusion energy for the grid in the next decade.

The 10-millisecond energy confinement time is the duration required to compress plasmas in LM26 to achieve key temperature thresholds of 1 keV, 10 keV, and, ultimately, scientific breakeven equivalent (100% Lawson). These results were imperative to de-risking LM26. The demonstration machine is now forming plasmas regularly, and the company is optimizing its plasma performance in preparation for compressing plasmas to create fusion and heating from compression.

Quotes:

“LM26 is designed to achieve a series of results that will demonstrate MTF in a commercially relevant way. Following LM26's results, our unique approach makes the path to powering the grid with fusion energy more straightforward than other technologies because we have front-loaded the work to address the barriers to commercialization.”

Dr. Michel Laberge
Founder and Chief Science Officer

“For over 16 years, I have worked hand in hand with Michel to advance General Fusion's practical technology. This company is entrepreneurial at its core. We pride ourselves on building real machines that get results that matter, and I'm thrilled to have the achievements recognized in Nuclear Fusion .”
