ESS Council Visits Jülich for the First Time

ESS highest governing body gains an overview of Jülich’s contributions

On 4 December, the highest governing body of the European Spallation Source (ESS), the "ESS Council", visited Forschungszentrum Jülich for the first time. On site, the delegates gathered first-hand information about Jülich’s contributions to the ESS. The visit took place as part of the Council's 17th Meeting. The ESS Council consists of up to two delegates from each member state. It is chaired by Dr. Beatrix Vierkorn-Rudolph, formerly of the German Federal Ministry of Education and Research (BMBF).

 

ESS is currently under construction in Lund, Sweden. In 2023, it is due to start operations as the world's most powerful neutron source, enabling scientific breakthroughs in areas such as materials research, energy, health and the environment.

Forschungszentrum Jülich contributes to the so-called "target station" of the ESS. Here, high-energy neutrons are released by the impact of accelerated protons on the actual tungsten target and then cooled and decelerated to speeds necessary for the experiments. The Central Institute of Engineering, Electronics and Analytics - Engineering and Technology (ZEA-1) is responsible for the design, analysis, assembly, testing and commissioning of key components, such as the moderator and reflector system, the target monitoring plug, the neutron beam extraction system and neutron beam choppers.

In addition, the Jülich Centre for Neutron Science (JCNS), together with ZEA-1, contributes to four of the 15 research instruments funded by the ESS construction budget, and they are the leading laboratory for three of them. A small-angle scattering instrument called SKADI, a time-of-flight machine named T-REX, and two diffractometers, DREAM and MAGIC, will be built at Forschungszentrum Jülich over the next few years, allowing novel investigations to be carried out at the ESS. In this regard, Forschungszentrum Jülich is able to draw on decades of experience in the construction and operation of neutron scattering instruments, dating back to 1962.
