33 million liters of concrete have been used for the huge body of the house that encloses the target station, the place where the actual spallation takes place in the EES (European Spallation Source).

More precisely, this is where the current of protruding protons from a 500 meter long accelerator tunnel collides with a heavy tungsten core and turns into a torrent of neutrons.

- We usually say that we are building a neutron factory, summarizes Construction Manager Kent Hedin.

New opportunities in research

The neutrons open up entirely new opportunities in material research. Someone has made the comparison that the creation of the ESS, which will be clear by 2023, means the same breakthrough as when the optical microscope was replaced by the electron microscope.
