The Small Angle Neutron Scattering (YS-SANS) instrument is composed of : 1. The SANS diffractometer Yellow Submarine covers a Q-range of 0.003 to 0.7 Å-1 allowing to probe structures at length scales from 5 Å to 1500 Å. It has a wide range of applications from studies of defects and precipitates in materials, alloy segregation, surfactant and colloid solutions, ferromagnetics, magnetic correlations, polymers, proteins and biological membranes alike. The instrument is installed on the curved neutron guide No.10/2, with a 40x40 mm2 cross-section, made of (m=1.5) supermirrors. The beam is monochromatized by a multidisc type velocity selector, (L. Rosta: Physica B 174 (1991) 562) the rotation speed can be tuned between 700 and 7000 rot/min (wavelengths between 3 and 12 Å). The width Δλ/λ of the transmitted wavelength distribution can be varied between 12% and 30% by changing the tilt angle between the selector axis and the direction of the neutron beam. The collimation distance is 5 m. 2. The FSANS instrument is a recently built instrument at the Budapest Neutron Centre site, used for non-destructive study of the nano-structural features of various materials, among them archaeological objects. The studied size range is between 10 nm and 500 nm. Because of its technical characteristics, it is complementary to the Yellow Submarine SANS Instrument.
