The round combines €3.5M in private funding, led by First Momentum Ventures and co-led by Caelora, with €3.6M in public funding including a Horizon Europe grant. According to the company, X-rays can only get through a few centimeters of steel, while muons can pass through more than a metre of steel. MuRay plans to launch its first imaging service in 2027 using DESY's existing electron beam in Hamburg, with a full laser-driven accelerator system due in 2029, and aims to grow to about 25 staff by the end of 2027. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### How much funding did MuRay raise for its muon imaging technology? MuRay raised €7.1 million, combining a €3.5 million private round led by First Momentum Ventures and co-led by Caelora with €3.6 million in public funding, including a grant from the EU's Horizon Europe research programme. Other investors include Superangel VC, Nordic Science Investments, Mätch VC, Arcas VC and Tiny VC. _daily.dev surfaces funding rounds like this for those tracking deep tech investment trends._ ### Why would you use muons instead of X-rays to inspect metal parts? Muons can pass through more than a metre of steel and other dense metals, while X-rays only penetrate a few centimeters of steel. This makes muon imaging suited for inspecting thick metal components like reusable rocket engines and gas turbines, letting manufacturers spot hidden flaws that X-rays cannot reach, with scans taking minutes rather than hours. _Engineers evaluating inspection methods for thick metal parts can follow developments like this on daily.dev._ ### When will MuRay's muon imaging service become available for industrial use? MuRay plans to open its first imaging service for industrial customers in 2027, using DESY's existing electron beam in Hamburg. A full-scale system powered by a compact laser-driven accelerator is due in 2029. The company also plans its first real rocket engine test in 2027 with the German Space Agency at DLR. _daily.dev keeps manufacturing and aerospace engineers informed as new inspection technologies near launch._ ## Similar posts on daily.dev - [Berkeley Lab-Led Project Secures Funding to Develop a Transportable Muon Imager](https://daily.dev/posts/berkeley-lab-led-project-secures-funding-to-develop-a-transportable-muon-imager-3ezzkfuuw) · The Quantum Insider · 0 upvotes · 0 comments - [Ideon Technologies Joins Consortium for Laser-Driven Muon Imaging](https://daily.dev/posts/ideon-technologies-joins-consortium-for-laser-driven-muon-imaging-izdju8dmf) · The Quantum Insider · 0 upvotes · 0 comments - [Muon Space raises $250m from backers including Google and Salesforce](https://daily.dev/posts/muon-space-raises-250m-from-backers-including-google-and-salesforce-botaoniwr) · The Next Web · 0 upvotes · 0 comments - [Cambridge Heavy Industries has been quietly building a desktop fusion device](https://daily.dev/posts/cambridge-heavy-industries-has-been-quietly-building-a-desktop-fusion-device-mjflodty8) · TechCrunch · 0 upvotes · 0 comments - [The Exploration Company raises $450m to build a rocket engine](https://daily.dev/posts/the-exploration-company-raises-450m-to-build-a-rocket-engine-b9dq7ox7r) · The Next Web · 0 upvotes · 0 comments --- Tags: [#startup](https://daily.dev/tags/startup), [#deep-tech](https://daily.dev/tags/deep-tech) [View this post on daily.dev](https://daily.dev/posts/hamburg-s-muray-raises-7-1m-for-muon-imaging-of-rocket-engines-onnxiezv2) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"Hamburg’s MuRay raises €7.1M for muon imaging of rocket engines","url":"https://daily.dev/posts/hamburg-s-muray-raises-7-1m-for-muon-imaging-of-rocket-engines-onnxiezv2","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/hamburg-s-muray-raises-7-1m-for-muon-imaging-of-rocket-engines-onnxiezv2"},"datePublished":"2026-10-29T09:48:21.100Z","dateModified":"2026-10-29T09:48:52.129Z","description":"MuRay has raised €7.1M to build muon-based imaging for inspecting dense metal parts like 3D-printed rocket engines and gas turbines.
