abstract = {The High-Brilliance neutron Source (HBS) project [1]
develops a High-Current Accelerator-driven Neutron Source
(HiCANS) with a pulsed proton beam, a peak current of 100 mA
and an average power at the target of 100 kW. The concept of
such a HiCANS was published some years ago [2] indicating
the feasibility of such a facility with all of its
components: high-current accelerator, target station with
integrated moderator-reflector assemblies and neutron
instruments. All components require engineering development
and testing. The JULIC Neutron Platform was thus developed
as a testbed for all components and the investigation of
their interplay.The JULIC Neutron Platform uses a cyclotron
providing a tunable pulsed proton beam with a low current
but a variable frequency and pulse length to a spacious
experimental area. A target station shielding is placed in
its center with an empty inner core of 1 m3, able to
accommodate different moderator-reflector assemblies as well
as cryogenic moderators. The target station uses a tantalum
target for the conversion of protons to neutrons and has
eight spacious flexible ducts where moderator plugs for
neutron extraction or blind plugs are placed.First beam on
target was achieved in December 2022 with three instruments
in operation: reflectometer, diffractometer and detector
test stand. Further beamtime in 2023 is planned in order to
investigate different cryogenic moderators, to estimate the
performance of such a HiCANS and to perform further
experiments.At UCANS, we will present the JULIC Neutron
Platform, the experiments performed and the possibilities it
offers.[1] P. Zakalek, et al, J. Phys.: Conf. Ser., 1401,
