Investor brief
Swedish revival of the magnetic mirror concept
Executive Summary
Novatron Fusion Group is a Swedish revival of the magnetic-mirror concept with a novel field geometry claimed to be MHD-stable without the rotating-plasma or tandem complications that limited earlier mirror programs.
Strategic Thesis
A linear, open-ended mirror is mechanically the simplest fusion device — if stability can be solved, capex drops dramatically.

How Novatron Fusion Group sits vs peers
Linear open-ended magnetic mirror — claimed MHD-stable without the rotating plasmas earlier mirror machines required.
Class engineering bottlenecks
- Non-planar coil geometry historically required sub-millimetre manufacturing precision — the dominant cost driver.
- Heat exhaust in non-axisymmetric 3D geometry produces localised thermal peaking that threatens divertor plasma-facing components.
- Same tritium breeding and neutron-damage constraints as the D-T tokamak class.
LCOE drivers
- Coil manufacturing precision determines unit cost — simplified-geometry approaches (Thea, Renaissance) target order-of-magnitude reductions.
- Higher capacity factor than tokamaks (no disruption downtime) materially improves LCOE.
- Liquid-metal blankets (Helical, Renaissance) double as first-wall, breeding blanket, and heat exchanger — collapsing three subsystems into one.

Founding Team
Novatron Fusion Group was established in Sweden to revive and perfect one of the most elegant, historically overlooked reactor designs: the magnetic mirror. Technical innovator Jan Jäderberg devised a novel, mathematical configuration of magnetic fields that actively corrects the plasma leakage issues that plagued 20th-century mirror machines. Partnered with industrial venture architects Erik Odén and Peter Roos, the KTH alumni have formed an agile engineering group that is rapidly building prototypes to demonstrate a highly stable, continuous-confinement reactor devoid of the complex instabilities found in tokamaks.

The Problem
Global electricity demand is entering an unprecedented growth phase driven by AI infrastructure, data centers, transport electrification, industrial decarbonization, water desalination, and advanced manufacturing. Solar suffers intermittency, wind capacity-factor variability, natural gas carbon emissions, conventional nuclear cost and deployment speed, and batteries energy-density and duration limits. The world requires a new source of clean, dispatchable baseload energy. Fusion represents the ultimate energy source — the challenge is making it commercially practical.
Novatron Magnetic Mirror
A linear, open-ended mirror is mechanically the simplest fusion device. Earlier mirror programs were defeated by end-loss and MHD instabilities; the Novatron field geometry is designed to suppress both.
Novel Mirror Geometry
A new field topology designed to be MHD-stable without requiring tandem cells or rotating plasmas.
Novatron 1 Prototype
First-plasma device demonstrating the field geometry's basic confinement properties.
Open-Ended Architecture
Linear geometry simplifies fuelling, exhaust and maintenance.
Fuel Strategy
Deuterium-Tritium
Standard D-T fuel cycle at the device-prototype stage.
Product Platform
Novatron 1
First-plasma magnetic mirror prototype.
Energy Conversion
Thermal (Rankine/Brayton)
Neutronic (D-T)
33–40% electrical
Deuterium-tritium fusion releases ~80% of its energy as 14.1 MeV neutrons, which deposit their kinetic energy in a surrounding blanket. The heat drives a conventional steam (Rankine) or supercritical-CO₂ (Brayton) turbine.
Conversion chain
- 1D-T plasma
- 214.1 MeV neutrons (80%) + 3.5 MeV alpha (20%)
- 3Neutrons → lithium-bearing blanket (heat + tritium breeding)
- 4Heat → steam/CO₂ turbine → electricity
The most thoroughly understood fusion fuel cycle, highest cross-section at achievable temperatures, and proven back-end engineering (steam turbines are 19th-century technology). Trade-offs: neutron-induced materials damage, tritium handling, ~33–40% Carnot-limited efficiency.
Economic Vision
If end-loss confinement is solved, the magnetic-mirror's mechanical simplicity translates to dramatically lower reactor capex than tokamaks or stellarators.
Vision
Make the magnetic mirror — the simplest fusion device ever built — work.
Mission
Demonstrate stable mirror confinement and scale to a fusion power plant.
Engineering Bottlenecks
- End-loss confinement
- Mirror-throat heat flux
Milestone Timeline

The description above reflects Novatron Fusion Group's publicly stated technology goals, roadmap and architecture. Many elements — particularly net-energy gain at scale, advanced fuel cycles, and grid-relevant economics — remain ambitious objectives that have not yet been demonstrated commercially anywhere in the fusion industry. Forward-looking statements should be treated as engineering targets, not certainties.
