ESS is a European collaboration to build the world's most powerful accelerator-based neutron source.

ESS (European Spallation Source ERIC) is a research facility under construction in Lund, with its data management and software centre in Copenhagen. When completed, ESS will be the world’s most powerful accelerator-based source of neutrons. Once generated, the neutrons are used to study the properties and behaviour of materials that would otherwise be impossible to see – right down to the level of atoms. Every year, thousands of researchers from academia and industry will use the ESS facility to learn more about materials; unlocking discoveries and driving innovative solutions to address some of humanity’s biggest challenges in energy, health and the environment. Funded by 13 European countries, the ESS facility is built with contribution from more than 40 research institutes. ESS attracts people from diverse fields and cultures who share the excitement of building a state-of-the-art facility to enable great science and innovation for a sustainable world.

🌞 A summer at ESS

This year’s Summer Workers have been learning, collaborating, and getting a behind-the-scenes look at life at one of Europe’s largest research facilities ahead of first science.

Hear what it’s like to spend a summer contributing to the future of neutron science.

🚀 Big progress for FREIA at ESS!

Key components are now in place inside the instrument cave, bringing FREIA one step closer to full integration 🔧

✅ Detector bench and guard assembly installed
✅ Collimation vessel in place
✅ Base for the hexapod system installed

🤝 Great teamwork on site with visiting colleagues from Neutron and Muon Source STFC working alongside ESS teams.

🥽 The visitors also tested the VR environment developed by the ESS Spatial Integration team, showcasing how virtual tools can support training and future installation planning.

👏 Huge thanks to everyone at ESS and STFC involved in the installation work. Collaboration and shared expertise are helping turn FREIA into reality.

A summer at ESS ☀️

Over the next few months, our 2026 Summer Workers will join teams across science, engineering, IT, administration, and technical services, contributing to projects that help keep ESS moving forward.

💡 For many, it’s a first experience inside a large international research facility. A summer of learning, collaboration and getting hands-on with real-world challenges alongside colleagues from across Europe and beyond.

We’re excited to welcome this year’s group and can’t wait to see what the summer brings.

✨ This is the moment ESS reached another major milestone on the road to first neutrons.

Beam on Dump 2 is complete.

After four months of accelerator commissioning, ESS teams successfully achieved stable beam delivery to the tuning beam dump at an energy of 800–860 MeV, while seperately increasing pulse length, repetition rate, and beam current.

Behind this achievement are countless hours of collaboration, precision, problem-solving, and persistence from teams across ESS. Every increase in beam power requires magnets, RF cavities, diagnostics, controls, and many other systems to work together in perfect coordination.

📸 In the first photo, ESS Director General Helmut Schober shuts down the beam, marking the successful completion of the Beam on Dump 2 commissioning phase, and another significant step towards first neutrons.

✨ What does a neutron source look like from the inside?

The Source is a collaboration between artist and ESS scientists, exploring how neutron activation and imaging could create a portrait of the ESS moderator.

As ESS moves closer to Beam on Target, the research continues...

🚀 FREIA is rapidly taking shape!

🇸🇪🇬🇧 Installation and integration work advances across the instrument with teams from ESS and ISIS Neutron and Muon Source working together on multiple systems.

Major support structures are now in place for future beamline and sample systems, including the hexapod setup that will precisely position samples during experiments.
