Sweden takes extra responsibility by hosting one of the world’s most powerful neutron sources. Researchers using the instruments at ESS will be able to study materials used in citizens’ daily lives, from plastic to proteins, to medicines and molecules, to understand how they are constructed and how they work. The project contributes to laying the foundation for ESS to open the way for future research breakthroughs in medicine, environmental science, climate, communication and transport by completing the goal of two instruments and supporting researchers in direct connection to the entire instrument programme. With these clear goals, the project will ensure the continuation and quality of the neutron source through the instruments, thereby ensuring that the instrumentation gets the right conditions for excellent research and that the neutron source itself is developed for the best performance. By participating in the ongoing instrument programme, researchers from the Swedish research community also ensure the Swedish ability to transfer knowledge to Swedish small and medium-sized companies. The building of knowledge lies in the future collaboration between academia and companies. Main content of the project: —Instructions 1; Test Beam Line instrument (TBL). TBL plays a crucial role in ESS’s long-term capacity and performance. TBL will show the first neutrons that ESS will deliver, thus becoming the first instrument to measure neutrons. During the operational phase, it is TBL that helps and develops existing instruments while at the same time fulfilling an important function in the development of new instruments. —Develop a resource during the project as Neutron Instrument Lead Engineer (NILE) to coordinate and integrate the installation and commissioning of the entire ESS instrument program (a total of 15 instruments). The person will lead and support the instrument projects and the goal is to involve Swedish expertise on the breadth of the instrument programme and to utilise the industrial engineering expertise that Sweden has. —Instructions 2; I'm Ymir. The instrument is the equivalent of TBL but for all data-driven systems. Here it is about testing and categorising data management of both chopper systems and instrument systems to secure capacity and performance. Ymir will also be able to be used for future development and upgrades of both systems, as well as control and measurement methods. It will be an existing important component in order to ensure and guarantee a long-term operation of ESS. —Create a collaboration between the Swedish Research Council and a number of Swedish universities and develop a network of researchers who can enter eight of the instrument projects that are first in the plan. Today, there is a shortage in the instrument programmes in terms of Swedish expertise and the Swedish neutron society’s ability to participate and influence the development of the various disciplines covered by the instruments.
