AB  - For modern neutron scattering facilities, effective generation of neutrons and their transmittance to smallvolume samples are very important. Particularly, in neutron macro-molecular crystallography, the samplesare very small, sometimes between 0.01 mm3 and 1 mm3 [1, 2]. A high-intensity compact neutron source(HICANS) will be ideally suited for experiments that require the measurement of small samples [3, 4], andSELENE neutron guides are a promising option to enables the beam spot shaping at a virtual sourceposition far away from the sample [5, 6]. In this work, SELENE neutron guides have been simulated fora potential neutron diffractometer for macro-molecular crystals at the Jülich High Brilliance Source (HBS).With the optimized guide geometry, we can obtain a low background tunable neutron beam for a samplewith a cross section as small as 1 mm2 with a flux comparable or even higher than that of existinginstruments at spallation neutron sources or medium flux reactor sources.
