Case history – European Spallation Source
Enabling cutting edge neutron research through advanced cooling solutions
The European Spallation Source is a multi-disciplinary research facility outside Lund, Sweden, with a vision to build and operate the most powerful pulsed neutron source in the world. Neutron research enables the detailed study of matter, with the potential to unlock breakthroughs in energy science, environmental technology, healthcare and fundamental physics.
At ESS, the process of creating neutrons begins with a linear proton accelerator. Protons are guided into the linear accelerator, which focuses a proton beam towards the neutron source: a custom-built tungsten target. This process, called ‘spallation’, causes a collision between protons and the nuclei of the tungsten target which triggers high energy neutrons to be scattered. The scattered neutrons are then examined at a series of experimental stations to investigate the nature of materials.
