Science & Instruments

The goal of scientific excellence drives the European Spallation Source project. At the heart of the ESS scientific user programme is the ESS instrument suite, together with sample environment equipment, user labs and data analysis support.

Instruments for ESS and their support infrastructure are under construction with a high level of community involvement through in-kind and collaboration, ensuring a long-term connection to the neutron science community and engagement with the users of tomorrow.

On these pages, the work to build the instrument suite and the supporting infrastructure is demonstrated, along with the technological research and development projects enabling these next-generation neutron instruments to maximise the scientific potential of the ESS facility. The staggering range of science areas that will benefit from ESS is highlighted, with examples of the current science being done with neutrons.
