520 _ _ |a Neutron protein crystallography requires a highly brilliant beam in order to measure very small biological single crystals, which typically measure between 0.01 and 1 mm³. Additionally, these crystals have a large unit cell size, which may be as large as 200 Å in at least one dimension. This makes it challenging for neutron beamlines to accommodate this type of measurement. The Jülich High Brilliance Neutron Source is a potential future source of neutrons for Germany. As part of this project, the design and simulation of a macromolecular diffractometer at the 24 Hz TMR station with a conventional 80 m long neutron guide using a cold moderator is planned. An optimized elliptical guide was developed for a neutron bandwidth of 2-4 Å. Simulations suggest that the 80 m instrument will have a flux of 3.3×106 n/s/cm² and a brilliance transfer of 91.7% within a divergence of ±0.4°. Furthermore, it is proposed that the diameter of the smallest moderator should be 14 mm.
