ESS - European Spallation Source

The European Spallation Source, ESS, will be the largest and most advanced neutron scattering facility in the world—and the first major international research facility to be located so close to Denmark. ESS is being built in Lund, Sweden, and the facility is expected to come online in 2022.

Neutron radiation opens up remarkable opportunities for studying the internal structure and dynamics of all kinds of materials. Siting a world-leading facility in the Øresund Region will provide Danish companies and researchers with excellent access to the benefits it offers. The ESS installation is expected to attracted a host of companies and researchers—particularly those specializing in the fields of material technology and life sciences—to the Øresund Region, Sweden and Denmark.

Knowledge about the structure and dynamic properties of materials is of relevance in the context of developing new everyday items such as faster computers, improved cleaning agents and more efficient pharmaceuticals; it also has a key role to play in the work to find solutions to the pressing societal challenges we are facing in the areas of climate, energy and transport, for instance.

ESS will be not only the most powerful, but also the most advanced neutron source in the world. The actual experiments on the neutron source will be performed at the facility in Lund, while the associated data processing will take place at the ESS Data Management and Software Centre (ESS DMSC) in Copenhagen.

DTU is responsible for a number of areas, including developing some of the highly specialized instruments that need to be constructed for the neutron source, where they will be used to take a variety of measurements in the future. In addition, DTU has been awarded responsibility for several of the lighthouse projects that form part of the national ESS strategy, and which are intended to support partnerships with the business community, for example.

The parties behind ESS

ESS is owned jointly by 18 European countries, forming what is known as an ERIC—European Research Infrastructure Consortium.

While the research facility itself is being built in Lund, data processing of the results will take place at ESS DMSC in Copenhagen
