Hamburg-based deep tech startup MuRay raised €7.1 million to inspect dense industrial components using subatomic particles called muons. The round combines €3.5 million in private venture capital with €3.6 million in public grants, including backing from the EU Horizon Europe research program.
The technology lets engineers look inside solid metal hardware where traditional X-rays cannot reach.
Why It Matters
Commercial ImplicationsRocket engines and power turbines increasingly rely on complex 3D-printed metal parts that run at extreme temperatures and pressures. Traditional non-destructive testing tools like X-rays fail to pierce thick, dense metals, leaving hidden internal flaws undetectable.
MuRay solves this critical quality assurance bottleneck, giving aerospace and energy manufacturers a reliable way to verify hardware before launch.

Key Developments & Takeaways
- Funding structure: €3.5 million in private capital paired with €3.6 million in public grants from Horizon Europe.
- Core technology: Muons pass straight through dense alloys that scatter and block standard X-rays.
- Commercial focus: First rollouts target additive-manufactured rocket combustion chambers and heavy industrial gas turbines.

The Big Picture
Hamburg-based startup MuRay has secured €7.1 million in fresh financing to scan the insides of dense metal parts using muons. The capital is split nearly evenly, pairing a €3.5 million private venture round with €3.6 million in non-dilutive public research grants, including funding from the European Union's flagship Horizon Europe program.
MuRay is tackling a major pain point in modern heavy engineering: non-destructive testing for solid metal components.
How the Technology Works
Modern aerospace and energy firms build complex parts using metal 3D printing. These components, such as rocket combustion chambers and gas turbine blades, contain internal channels that must survive extreme heat and pressure.
- The X-ray wall: Standard industrial X-rays and computed tomography (CT) scanners cannot easily penetrate thick, high-density metals like nickel superalloys or solid steel.
- The particle solution: Muons are naturally occurring subatomic particles generated when cosmic rays hit Earth's atmosphere. They possess far greater mass than electrons, allowing them to pass clean through dense matter without scattering.
- Actionable imaging: By tracking how muons deflect as they travel through a structure, MuRay builds high-contrast three-dimensional maps of internal cavities, voids, and structural defects.
Why It Matters
For space launch providers, a single microscopic flaw inside a 3D-printed engine nozzle can cause catastrophic loss of vehicle during liftoff. Current inspection methods often force manufacturers to rely on expensive sample cutting or uncertain acoustic tests.
MuRay gives quality assurance teams a way to inspect the exact part that will fly. By cutting inspection failure rates, space firms can accelerate production schedules and slash insurance costs.
Strategic Verdict
MuRay proves that frontier particle physics is finding practical, high-value commercial uses in European manufacturing corridors. The backing from Horizon Europe shows Brussels wants to anchor strategic space infrastructure and inspection intellectual property inside the EU.
