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.},
