Past and present of time-of-flight small-angle neutron scattering at IBR-2

A historical overview of MURN-YuMO instrument (including some technical and scientific development prospects) is presented. Numerous references are cited which demonstrate a tireless activity on the first in the world SANS machine functioning at a neutron pulsed reactor. The relevant scientific activity trajectories of Yu.M.Ostanevich and his colleagues are retraced and put into perspective.
