European Spallation Source (ESS) is a materials research facility for scientific research using the neutron scattering technique. The facility will be built in Lund, Sweden starting in 2013. The facility is expected to open in 2019 and will be fully operational in 2025. At present 17 partner countries are represented in the ESS Steering Committee.
The laboratory is designed around a linear accelerator in which protons are accelerated and collide with a heavy metal target. By this process, intense pulses of neutrons are emitted and led through beamlines to experimental stations, where research on materials is done as part of the scientific front line in energy, telecommunications, manufacturing, transportation, information technology, biotechnology, and health.
ESS will become 30 times more powerful than facilities in the US and Japan.
Since July 1, 2010, the staff and operations of ESS Scandinavia were transferred from Lund University to European Spallation Source ESS AB, a limited liability company set up to design, construct, own and operate the European Spallation Source in Lund. The company's headquarters are situated in central Lund, Sweden.
