The European Spallation Source ERIC ( ESS ) is a major research facility under construction in Lund , Sweden . It is supposed to supply neutron radiation for materials science and engineering. Construction began in 2014, and user operations are scheduled to begin in 2023 Template: future / in 3 years. The construction, including the first 15 scientific instruments, will cost around 1.8 billion euros (as of 2017); Sweden contributes 35%, Denmark 12.5% ​​and Germany 11%. The running operating costs are estimated at around 140 million euros annually.

After the Laue-Langevin Institute founded in 1967 , the ESS will be the second multinational neutron source for research purposes in Europe.


The first plans for a European spallation source began in 1993. On May 28, 2009, the European research ministers in Brussels decided on the location of Lund. In the run-up to this, archaeological investigations were carried out on the planned building site in 2013, but they did not reveal any notable findings. The foundation stone was laid in October 2014.


A proton beam with an energy of 2 GeV falls in pulses of 62.5 mA current and 2.9 ms duration on a rotating, 5 ton tungsten target . Here are Spallation 10 18 neutrons per second released. The ESS will be home to up to 22 experiment stations that will be operated simultaneously. A special synergy with the neighboring synchrotron MAX-LAB is seen here, as both systems can complement each other.

Transport links

From 2020 the Lund tram will provide a fast connection with Lund Central Station .
