Abstract: Aiming to develop a high-current accelerator-driven neutron source (HiCANS), the High BrillianceNeutron Source (HBS) project has extensively detailed its technical aspects in the conceptual andtechnical design reports [1][2]. The facility, based on a high-power linear proton accelerator deliveringa 70 MeV proton beam with a peak current of 100 mA, is designed to supply three distinct targetstations operating at different pulse frequencies. Each target station will provide pulses optimizedfor specific instrument groups, ensuring efficient use of the available beam and supporting a competitivesuite of instruments.A next step is the realization of an HBS Science Demonstrator, which aims to assess the scientificpotential of HiCANS, providing a proton beam power of approximately 10 kW. It will feature a selectionof highly demanded neutron instruments, among them a small angle neutron scattering (SANS)instrument. For this, we will present a conceptual design including ray-tracing Monte Carlo simulationsusing the software VITESS to optimize instrument parameters. Virtual experiments on selectsamples, representing typical use cases, will be used to quantify the instrument performance.[1] Thomas Brückel et al.
