In a groundbreaking achievement, Canadian company General Fusion has shattered previous records by generating 600 million neutrons per second using Magnetized Target Fusion (MTF). This milestone, recognized by the International Atomic Energy Agency (IAEA), marks a significant step toward achieving stable and scalable fusion energy, bringing humanity closer to the dream of limitless, clean power.

The Innovative Plasma Compression Approach
How Magnetized Target Fusion Works
Unlike conventional nuclear fusion methods, General Fusion’s MTF technology employs a unique liquid metal liner that is mechanically compressed by high-powered pistons. This approach facilitates rapid plasma compression within a spherical tokamak, creating the extreme conditions necessary for fusion.
During recent Plasma Compression Science (PCS) experiments, this technique produced an unprecedented neutron output, setting a new standard for plasma compression-based fusion technology.
Key Advancements in Plasma Stability and Density
The breakthrough achieved by General Fusion also delivered several remarkable advancements:
- Plasma Density Increase: The plasma density surged to 190 times its initial state, demonstrating exceptional containment and compression efficiency.
- Extended Particle Confinement Time: The stability of the plasma was reinforced by a longer confinement time than the actual compression period, a crucial factor for maintaining sustained fusion reactions.
- Enhanced Magnetic Field Strength: The magnetic field strength increased more than thirteenfold, improving plasma containment and reducing energy losses.
These improvements collectively validate the practicality and effectiveness of MTF technology, making it a serious contender in the race to develop commercial nuclear fusion.

Dr. Michel Laberge’s Vision for Fusion Power
Dr. Michel Laberge, founder and Chief Scientist of General Fusion, underscored the importance of this milestone, stating:
“This is the first-ever compression of a spherical tokamak using a collapsing metal liner. These results strengthen MTF as a viable path to commercial fusion energy and pave the way for large-scale implementation.”
This breakthrough sets the stage for General Fusion’s next major project: the Lawson Machine 26 (LM26)—a prototype designed to scale up plasma compression, enhance fusion yields, and accelerate the transition to practical fusion power.

Building on Experimental Success
The recent PCS experiments have confirmed that metal liner compression is both feasible and effective, significantly de-risking the development of LM26. This upcoming large-scale prototype aims to:
- Demonstrate sustained fusion heating
- Increase neutron production for energy generation
- Validate the long-term commercial viability of MTF-based fusion reactors
LM26 represents a crucial next step in proving General Fusion’s technology at power plant scale, with the goal of achieving grid-ready fusion energy.
A Path Toward Clean and Cost-Effective Fusion Energy
Why MTF is a Game-Changer
General Fusion’s pulsed fusion approach distinguishes itself from other fusion strategies by avoiding the need for continuous reactions, which can be challenging to sustain. The key benefits of this method include:
- Eliminating the need for massive superconducting magnets or high-powered lasers, reducing costs and complexity
- Efficient heat extraction and fuel regeneration, enhancing reactor longevity
- Greater protection for reactor components, minimizing long-term wear and tear
The results, published in the journal Nuclear Fusion, confirm that this compression-based fusion experiment is the most successful of its kind to date.

Scaling Toward Commercial Fusion Power
Mike Donaldson, Senior Vice President of Technology Development at General Fusion, reinforced the impact of these findings:
“This breakthrough proves that stable fusion reactions using MTF are not just possible, but scalable. Our decades of research have built a strong foundation for LM26, which will showcase fusion heating and energy production at a commercial scale.”
A Timeline for Fusion Power Deployment
General Fusion is now preparing for the next phase, aiming to achieve transformative technical milestones within the next 24 months. Their ambitious timeline includes:
- Finalizing LM26’s large-scale compression system
- Increasing energy yields to commercial levels
- Delivering the first commercial fusion power to the grid by the early-to-mid 2030s
If successful, this could revolutionize global energy infrastructure, offering an inexhaustible, zero-carbon energy source that would fundamentally reshape how the world powers itself.
