Abstract: The advent of high-current accelerator systems launched the development of high-current accelerator-driven neutron sources(HiCANS) utilizing low energy nuclear reactions. This development can counteract the increasing shutdown of existingfission-based neutron sources and a resulting decline in available neutron beam days as well as establishing HiCANS as a nextgeneration national neutron source. A main component of a HiCANS is the target station used to release neutrons, to moderatethe neutrons to the required energy in the keV or meV range, to extract the neutrons to the instruments with the proper phasespace volume as well as to shield the surrounding equipment. Within the High-Brilliance neutron Source (HBS) project, threetarget stations will be operated simultaneously with one long pulse, and two medium pulse proton beams. The target stations havetarget / moderator / reflector geometries optimized to the specific proton beam structure resulting in tailored neutron beams fordifferent groups of neutron instruments. At the ECNS conference, we will present the general design ideas of such HiCANS targetstations, show the flexibility they offer and present the resulting TMR assemblies for the HBS project. This work is part of thecollaboration within ELENA and LENS on the development of HiCANS.
