Abstract: The High Brilliance neutron Source (HBS) project aims to develop a scalableCompact Accelerator-driven Neutron Source (CANS) enabling neutron fluxesat the corresponding instruments comparable to medium-flux fission-based re-search reactors. The full-fledged HBS facility features simultaneous operationof different neutron instruments which subdivide into three target stations eachefficiently operated to supply different neutron energies. This will be realized bydifferent proton beam timing schemes distributed to the target stations in orderto obtain the optimal balance between wavelength bandwidth and resolution ofthe time-resolved neutron spectrum extracted from the thermal or cold neutronmoderator according to the requirement of the experiment. For this reason aproton pulse distribution device, i.e. multiplexer, has to be developed. Thispresentation includes developments of a multiplexer test setup at the 45 MeVCOSY injector JULIC in Juelich as well as concepts towards an implementationof such device into the final 70 MeV HBS framework.
