      abstract     = {Accelerator-driven neutron sources offer a cost-effective
                      alternative to traditional sources such as fission reactors
                      and spallation sources. The advent of high-current proton
                      accelerator systems has given rise to a new class of neutron
                      facility, termed High-Current Accelerator-driven Neutron
                      Sources (HiCANS), which has unique properties and
                      capabilities.The High-Brilliance Neutron Source (HBS)
                      project at Forschungszentrum Jülich is developing a HiCANS
                      facility. It uses a linear accelerator with a pulsed proton
                      beam and a peak current of up to 100 mA to provide
                      customised proton pulses at variable frequencies to
                      optimised target stations. These target stations are more
                      compact than spallation neutron sources because low-energy
                      nuclear reactions release neutrons from a high-power
                      tantalum target. This allows for efficient neutron
                      production, moderation and extraction, enabling competitive
                      neutron instrument performance.A detailed Technical Design
                      Report (TDR) has been published describing all the relevant
                      components, from the accelerator and target to the
                      moderators and instruments. It demonstrates the potential of
                      a national neutron source facility with up to 24 instruments
                      for a variety of applications. A target station prototype
                      was built at a 45 MeV cyclotron and brought into operation
                      producing first neutrons in December 2022. Experiments
                      demonstrated the accessibility and flexibility of this new
                      type of source and allowed the expected performance to be
                      evaluated. The first stage, HBS-I, is planned to have a
                      proton energy of 20 MeV, a neutron yield of 10¹⁵ n/s, and
                      five instruments at a single target station: SANS, a
                      reflectometer, a diffractometer, an imaging instrument and a
                      PGNAA instrument.I will present the current status of the
                      High-Brilliance Neutron Source (HBS) HiCANS project, as well
                      as the next steps and milestones for this next-generation
                      neutron source.},
