Lawson Machine 26 (LM26)
Validates commercial magnetized target fusion scaling using compact toroid injection.
01 Definition
General Fusion's Magnetized Target Fusion demonstration platform in Canada, achieving first plasma in March 2025.
02 Detailed_Analysis
The LM26 (Lawson Machine 26) is an experimental Magnetized Target Fusion (MTF) demonstration device developed by General Fusion in Richmond, British Columbia. Designed to validate fusion conditions without full liquid metal compression, LM26 integrates full-scale compact toroid (CT) plasma injectors to form and compress high-temperature field-reversed configuration or spheromak plasmoids, successfully achieving its first plasma milestone in March 2025.
03 Key_Facts
- ▸ Developed by General Fusion in Richmond, British Columbia, Canada
- ▸ Achieved first plasma milestone in March 2025 as an MTF validation platform
- ▸ Employs power-plant-scale compact toroid plasma injectors for target formation
- ▸ Aims to achieve breakeven-relevant fusion conditions via magnetic compression
04 Deep_Dive_Intelligence
Intelligence Summary: LM26
Node Identity: LM26 is a entity categorized under "MCF" in the canada intelligence graph. General Fusion's demonstration machine achieving first plasma in March 2025, validating MTF approach with compact toroid injectors.
Research Evidence: The following findings from 4 research documents reference this entity:
-
- General Fusion (Canada): World leader in magnetized target fusion using compact toroid plasma injectors — "first in the world to design, build, and commission a compact toroid plasma injector at power plant scale." LM26 demonstration machine achieved first plasma (March 2025).
- The company's scale (150+ employees, $733M funding, LM26 operating) makes this Canada's premier compact toroid program.
- The 2027-2028 timeline convergence across multiple companies (CFS SPARC 2027, Helion Microsoft contract 2028, General Fusion LM26 2028) appears driven by commercial/venture capital dynamics and the AI energy demand surge, not by coordinated classified program milestones.
- General Fusion's 2028 target is for LM26 Lawson criterion, a physics milestone, not a commercial delivery Evidence against coincidence: 1.
Strategic Relevance: LM26 is a tracked entity within the canada network. With 2 documented connections to other entities, this node plays a supporting role in the network topology.
Network Linkage: This entity maintains 2 documented connections in the intelligence network: LM26 uses Compact Toroid Injector; General Fusion operates LM26.
