Introducing Alpha
Alpha is Proxima Fusion’s demonstration stellarator, Europe’s industrial bridge from advanced fusion research to commercial deployment.
Designed to achieve net energy gain (Q>1) from a stellarator for the first time, Alpha validates the manufacturing methods, materials, and high-performance systems that will define future stellarator power plants.

About The Alliance
The Alpha Alliance brings together industrial companies and public research institutions with deep expertise in the design, manufacturing, and integration of components for fusion devices, aligning Europe’s strong fusion ecosystem behind a concrete engineering project.
The purpose of the Alliance is not only to deliver Alpha, but to build the supply chains and industrial capabilities required for future commercial stellarators –including Proxima’s first-of-a-kind fusion power plant, Stellaris.
What the Alliance Does
The Alpha Alliance builds on Europe’s long-standing leadership in fusion engineering, based in Wendelstein 7-X (W7-X), ITER, and national programs across Germany, France, Italy, Spain, Switzerland, and the UK.
Members contribute capabilities across superconducting technology, coil manufacturing, power systems, cryogenics, advanced materials, vacuum engineering, diagnostics, precision mechanical structures, and more.
Industrial Ecosystem
Aligning industrial interfaces across suppliers, engineering teams, and research partners
Manufacturing
Ensuring manufacturability of complex components at industrial scale
Technical Integration
Supporting technical integration across superconducting systems, coils, magnets, diagnostics, and plant subsystems
Supply Chains
Preparing supply chains and production processes for future first-of-a-kind machines
Delivery
Translating research capabilities into industrial delivery pathways
Members of the Alpha Alliance
With members based in Germany, France, Italy, Spain, Switzerland, Japan, Sweden and the UK, the Alpha Alliance unites the entire European fusion supply chain around an ambitious German engineering project.
