This satellite meeting to the SAS2012 conference focuses at the contemporary tendency in ultra-small-angle scattering to develop Bonse-Hart double-crystal diffractometers operating with the high-orders of the Bragg reflection. This approach leads to a dramatic improvement of the Q-resolution (Q min) of the USANS and USAXS instruments, which is very important for studies of large-scale homogeneities (~ 10 μm - 100 μm); it also offers an opportunity to increase neutron flux at Qmax which is critical for USANS measurements of weakly scattering objects. Contributions will cover parameters and status of advanced USANS/USAXS instruments along
with recent experimental results obtained on large-scale structure.
