Description of YuMO

Small-angle neutron scattering is widely used in investigations of the supraatomic structure of matter as an efficient technique for studying fundamental problems and meeting the crucial technological issues. It is used in condensed matter physics, physical chemistry of disperse systems, surface-active substance aggregates, biophysics and molecular biology, in the research of polymeric substances, in metallurgy and other fields of science and technology. The key point of small-angle scattering is the possibility of analyzing the structure of disordered systems. This method, for instance, is often the only way to obtain direct structural data on systems with chaotic and partially ordered density inhomogeneities with characteristic sizes of 10-10000 Angstrom; it allows to study the disperse structure of alloys, powders, glasses (mechanisms of phase splitting, the size and degree of polydispersity of particles), structural features of polymers in various aggregate states, weight and geometric characteristics of biological macromolecules and their complexes, biological permolecular structures, such as biological membranes and viruses. The significant difference in neutron scattering lengths for hydrogen and deuterium, as well as the possibility of selective deuteration of macromolecules and permolecular structures, makes small-angle neutron scattering an indispensable tool for studying biological and colloidal objects, as well as polymers and liquid crystals.

The small-angle scattering was put into operation using the time-of-flight technique first at the IBR-30 reactor and later - at the high-flux pulsed reactor IBR-2 by Yury Ostanevich and his colleagues. The YuMO spectrometer (named after Yu. M. Ostanevich) provides a wide range of systematic investigations in various areas of condensed matter physics, physical chemistry and biology.

The basic components of the YuMO facility are the neutron beam development system, the sample assembly unit and the detector system.
