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.
