Supplementary Materials:General Guide Concepts for Compact, High-Brilliance Neutron Moderators

The supplementary materials include four figures. Figure S1 explains the workflow used for final optimizations (Sec. II B). Figure S2 shows the spatial inhomogeneity for all optimized guides (Fig. 4). Figure S3 compares the acceptance diagrams of the curved beamlines under different assumptions about gravity effects and the supermirrors' waviness and reflectivity (Sec. III D). Figure S4 shows the high-resolution angular distribution of the curved beamlines along the horizontal and vertical directions (Sec. III D).
