General Fusion's magnetized target fusion system uses a ~3 meter sphere filled with liquid metal. The liquid is spun, creating a vertical cavity in the centre of the sphere. This vortex flow is established and maintained by an external pumping system; liquid flows into the sphere through tangentially directed ports at the equator and exits radially through ports near the poles of the sphere.{{Cite news |url=https://www.euro-fusion.org/newsletter/general-fusion/ |title=Introducing alternative fusion concepts: General Fusion |access-date=2017-01-17 |language=en-US |work=EUROfusion |archive-date=18 April 2017 |archive-url=https://web.archive.org/web/20170418083520/https://www.euro-fusion.org/newsletter/general-fusion/ |url-status=dead}}

A plasma injector is attached to the top of the sphere, from which a pulse of magnetically confined deuterium-tritium plasma fuel is injected into the center of the vortex. A few milligrams of gas are used per pulse. The gas is ionized by a bank of capacitors to form a spherical tokamak plasma (self-confined magnetized plasma rings) composed of the deuterium–tritium fuel.{{Cite news |url=https://www.mitacs.ca/en/projects/magnetic-compression-and-stability-spheromaks |archive-url=https://web.archive.org/web/20170418083839/https://www.mitacs.ca/en/projects/magnetic-compression-and-stability-spheromaks |url-status=dead |archive-date=18 April 2017 |title=Magnetic Compression and Stability of Spheromaks |date=2014-11-17 |work=Mitacs |access-date=2017-04-17 |language=en}}{{Cite journal|last1=Gibbs|first1=Wayt|date=18 October 2016|title=Can Small Fusion Energy Start-Ups Conquer the Problems That Killed the Giants?|journal=Scientific American|volume=315|issue=5|pages=38–45|bibcode=2016SciAm.315e..38G|doi=10.1038/scientificamerican1116-38|pmid=27918497}}

The outside of the sphere is covered with steam pistons, which push the liquid metal and collapse the vortex, thereby compressing the plasma. The compression increases the density and temperature of the plasma to the range where the fuel atoms fuse, releasing energy in the form of fast neutrons and alpha particles.Image:General Fusion pistons (31634031395).jpgThis energy heats the liquid metal, which is then pumped through a heat exchanger to generate electricity via a steam turbine. The plasma forming and compressing process repeats and the liquid metal is continuously pumped through the system. Some of the steam is recycled to power the pistons.{{Cite news |last1=Hamilton |first1=Tyler |date=31 July 2009 |url=https://www.technologyreview.com/s/414559/a-new-approach-to-fusion/ |title=A New Approach to Fusion |access-date=2017-01-17 |work=MIT Technology Review |publisher=Massachusetts Institute of Technology}}

In addition to its role in compressing the plasma, the liquid metal liner shields the power plant structure from neutrons released by the deuterium-tritium fusion reaction, overcoming the problem of structural damage to plasma-facing materials.{{Cite journal |last1=Clinard |first1=Frank |date=1975 |title=First wall materials problems in fusion reactors |journal=Journal of Vacuum Science and Technology |volume=12 |pages=510|doi=10.1116/1.568576}} The lithium in the mixture breeds tritium.{{Cite news |last1=Grossman |first1=Lev |date=October 2015 |title=Inside the Quest for Fusion, Clean Energy's Holy Grail |url=https://time.com/4082939/inside-the-quest-for-fusion-clean-energys-holy-grail/ |magazine=Time}}

In August 2023, General Fusion announced it intends to build a new fusion demonstration machine named Lawson Machine 26 (LM26) to achieve important technical milestones using magnetized target fusion. LM26 aims to achieve fusion conditions of over 100 million degrees Celsius by 2025 and progress towards scientific breakeven equivalent by 2026.{{Cite web |title=General Fusion lands $25M and reveals plans for demo machine in B.C.|date=9 August 2023 |url=https://www.geekwire.com/2023/general-fusion-lands-25m-in-funding-announces-new-plans-for-demo-reactor-in-b-c/}}

LM26 will use a Marshall gun to inject a deuterium plasma into a target chamber. The target chamber’s outer wall is a solid lithium liner contained within a cylindrical composite vacuum vessel. Toroidal coils mounted on the outside of the cylindrical vessel are pulsed and push on the liner to initiate compression. As the liner collapses, the plasma is compressed to higher density and temperature.{{Cite web |last1=Braglia |first1=Filiberto |last2=Carle |first2=Patrick |last3=Rohollahi |first3=Akbar |last4=Howard |first4=Stephen |last5=Hildebrand |first5=Myles |title=Diagnostics for the General Fusion LM26 Machine |url=https://custom.cvent.com/DCBD4ADAAD004096B1E4AD96F3C8049E/files/event/c6850a6069dc489d93451d47a5d704d2/03514401903f4df6a9005f6f945eec00.pdf |place=Richmond, British Columbia, Canada}}

In January 2024, the company reported it had achieved symmetrical compression of a solid lithium ring within a few weeks of announcing LM26 and had built and began operating a compression test bed for LM26 named Prototype 0.{{Cite web |title=Innovation in Action: LM26 on Track After Swift 2023 Launch|date=31 January 2024 |url=https://generalfusion.com/post/innovation-in-action-lm26-on-track-after-swift-launch/}}

The plant had several key differences from the commercial power plant concept:

• 70% scale.
• 1 pulse per day repetition rate vs 1 pulse per second for a power plant.
• Among other things this increases the time available to re-establish the high vacuum conditions required for plasma formation by a factor of 86400, avoiding a significant engineering obstacle that will need to be solved for any future commercial application to be viable.
• Drive gas system using helium rather than hydraulic rams.{{Cite web |last1=Edwards |first1=Warren |date=7 July 2022 |title=Fusion Demonstration Plant UKAEA 8th Supplier Event |url=https://ukaeaevents.com/wp-content/uploads/2022/07/8-General-Fusion.pdf |access-date=28 January 2022}}
• A compression system using liquid lithium rather than lead-lithium.
• Ideally plasma facing materials should be composed of light elements. Plasma contamination by heavier elements, such as lead, significantly increase plasma power loss due to Bremsstrahlung radiation.{{cite book |doi=10.1016/B978-008042683-9/50014-5 |chapter=Fusion Energy Applications |title=Carbon Materials for Advanced Technologies |date=1999 |last1=Snead |first1=Lance L. |pages=389–427 |isbn=978-0-08-042683-9}} The choice of lithium rather than lead-lithium therefore significantly reduces plasma power losses making the demonstration program much more viable than it otherwise would be.

The 100 kg, 30 cm diameter hammer pistons were driven down a 1 m long bore by compressed air. The hammer piston struck an anvil at the end of the bore, generating a large amplitude acoustic pulse that was transmitted to the liquid metal in the compression chamber. To create a spherical wave, the timing of these strikes had to be controlled to within 10 μs. The firm recorded sequences of consecutive shots with impact velocities of 50 m/s and timing synchronized within 2 μs. However it was found that the wall of the liquid metal vortex turned to a spray soon after the arrival of the pressure wave.

From its inception until 2016, the firm built more than a dozen plasma injectors.{{Cite news|last1=Ambreen|first1=Ali|date=December 2016|title=Reviving the Fusion Dream|work=PM Network|url=http://www.pmi.org/learning/library/nuclear-reactor-private-sector-project-teams-10370|url-status=dead|access-date=24 March 2017|archive-url=https://web.archive.org/web/20171212031624/https://www.pmi.org/learning/library/nuclear-reactor-private-sector-project-teams-10370|archive-date=2017-12-12}} These include large two-stage injectors with formation and magnetic acceleration sections (dubbed "PI" experiments), and three generations of smaller, single-stage formation-only injectors (MRT, PROSPECTOR and SPECTOR).Peter O’Shea, Michel Laberge, Mike Donaldson, Michael Delage "[http://generalfusion.com/2016/11/acoustically-driven-magnetized-target-fusion-at-general-fusion-an-overview/ Acoustically Driven Magnetized Target Fusion at General Fusion: An Overview]" {{webarchive|url=https://web.archive.org/web/20170418084327/http://generalfusion.com/2016/11/acoustically-driven-magnetized-target-fusion-at-general-fusion-an-overview/|date=18 April 2017}} Poster presented at the 58th Annual Meeting of the APS Division of Plasma Physics 31 October – 4 November 2016.

Around 2017 the company performed a series of experiments named Plasma Compression Small (PCS). These implosion experiments used a chemical driver to compress an aluminum liner onto a compact toroid plasma. Because the implosions involved chemical explosives, the tests took place outdoors in remote locations. The tests were destructive and could only be executed every few months.

Magnetized target fusion has a number of challenges. General Fusion's founder and Chief Science Officer noted several specific difficulties that are not present in DC tokamaks. These include, but are not limited to:

• Confinement at high energy density is not known.
• Liquid metal vaporization. To address this challenge, the company is collaborating with Lawrence Livermore National Laboratory to better predict how its plasma will behave as it is compressed to fusion conditions in its MTF machine.{{Cite journal|title=Boundary plasma studies for a spherical tokamak with lithium walls |url=https://generalfusion.com/wp-content/uploads/2024/05/Spherical-Tokamak-Plasma-Studies-1.pdf|first1=Abetharan|last1=Antony|collaboration=A.
