Description

The High Brilliance Neutron Source (HBS) project involves the development of a next-generation neutron research facility based on new concepts and recent technological advancements. Unlike other facilities, it does not use fission or spallation but instead uses low-energy nuclear reactions in a compact assembly.
A prototype of the HBS Target-Moderator-Reflector (TMR) assembly has been designed, built and tested at the JULIC Neutron Platform in the Big Karl experimental area of the Cooler Synchrotron (COSY) at Forschungszentrum Jülich. This assembly enabled scientists to perform tests and develop target handling, moderator systems, target cooling systems and biological shielding.
The HBS prototype target, the thermal moderator and the reflector are surrounded by approximately 1 m of multilayer shielding. This consists of several layers of lead and borated polyethylene with a suitable support structure.
The main focus in this presentation is on the challenges and experiences encountered during the development, manufacturing and assembly phases. Lessons learned from the installation and commissioning of the shielding and shielding gates will be presented.
Finally, the next steps in the project and the planned transfer of the target station to ESS Bilbao will also be discussed.
