SANS2 is a general-purpose small-angle neutron scattering spectrometer providing relatively high resolution and relatively low minimum Q values. Figure 1 provides a schematic representation of SANS2, and Table 1 gives the parameters for this instrument. Because of the broad Q range sampled in a single measurement, this instrument will be particularly useful in the study of time-dependent phenomena, such as deformation/orientation and phase transformations in complex fluids and polymers
