MuRay Raises €7.1M for Advanced Material Imaging

Deeptech innovator MuRay has successfully closed a €7.1 million funding round, propelling its groundbreaking muon imaging technology toward industrial application. This significant capital infusion is earmarked for refining the company's Active Muon Imaging system, designed to peer inside the densest materials where conventional inspection methods fall short. The funding comprises €3.5 million in private investment, spearheaded by First Momentum Ventures and co-led by Caelora, a subsidiary of Marvel Fusion. Additional backing came from Superangel, Mätch VC, Arcas VC, and Tiny VC, alongside continued support from existing investor Nordic Science Investments. Complementing this private capital, MuRay also secured €3.6 million in non-dilutive public funding, including a substantial grant from the EU's Horizon Europe initiative.

Founded by visionary scientists Dr. Andi Hektor and Dr. Kristjan Põder, who now jointly lead the company, MuRay leverages controlled muon beams to generate high-resolution, three-dimensional images of internal structures. This capability is particularly crucial for quality assurance in sectors demanding extreme reliability. The company's initial market focus targets safety-critical components such as advanced 3D-printed rocket engines and gas turbine parts, where detecting microscopic internal flaws is paramount but exceedingly difficult with current technologies.

Traditional X-ray imaging struggles to penetrate materials thicker than a few centimeters of steel, a significant limitation for components used in aerospace and energy. MuRay's muon-based approach overcomes this hurdle, offering unparalleled insight into metals, ceramics, and composites. The system's ability to differentiate material composition and density allows for rapid defect identification, potentially reducing inspection times from hours to mere minutes. This advancement promises to enable manufacturers to identify flaws directly on production lines with a significantly lower radiation footprint than existing methods.

The implications for industries like space, aerospace, defense, and energy are profound. By enabling more thorough inspections of components such as reusable rocket engines and jet turbines, MuRay's technology could lead to shorter maintenance cycles and enhanced operational safety. The company is actively collaborating with institutions like the German Space Agency at DLR, with plans for a real-world demonstration of its rocket engine inspection capabilities scheduled for 2027. This project aims to validate the technology's effectiveness in identifying critical internal defects.

Beyond its core industrial applications, MuRay is exploring a diverse range of future use cases. These include enhancing security screening for cargo and border control, specifically for detecting illicit nuclear materials like uranium within dense shipments. Longer-term prospects extend to monitoring radioactive waste, inspecting large-scale infrastructure such as bridges and buildings, and even potential applications in clinical diagnostics. The newly acquired capital will be instrumental in advancing the technology's development and commercialization, including the creation of a mobile imaging unit, roughly the size of a shipping container, designed for on-site industrial inspections.
