Abstract: Accelerator driven neutron sources provide a cost-efficient and attractive alternative to classicalneutron sources like fission reactors and spallation sources. With the advent of highcurrent proton accelerator systems, a novel class of such neutron facilities can be establishedtermed High-Current Accelerator-driven Neutron Sources (HiCANS). Such sources cancounteract the increasing shutdown of existing fission-based neutron sources and a decline inavailable neutron beam days in Europe.The High Brilliance neutron Source project (HBS) [1, 2] at the Forschungszentrum Jülichdevelops such a HiCANS facility. It utilizes a 70 MeV and 100 mA pulsed proton linearaccelerator providing tailored proton pulses with frequencies of 24 Hz or 96 Hz up to threeoptimized target stations. Due to the low energy nuclear reactions releasing neutrons from atantalum target, the target stations are compact in comparison to spallation neutron sources,requiring only 4% of the shielding material. It allows for an efficient neutron production,moderation and extraction and thus allowing competitive neutron instrument performances.A detailed technical design report describing all relevant components ranging from accelerator,target, moderators up to the instruments was published recently. Due to the flexibilityand modularity in target station design, high performant instruments for basic applicationsas well as specialised applications for activation analysis can be built. It shows a potentialnational neutron source facility with up to 24 instruments for all kinds of applications.We will present the current status of the High-Brilliance Neutron Source (HBS) HiCANSproject. The next steps and milestones for this next generation neutron source will be reportedas well as he performance of instruments for activation analysis will be estimated.References1. P.
