40m Small-Angle Neutron Scattering Instrument

40m Small-Angle Neutron Scattering Instrument40M-SANS 40m Small Angle Neutron Scattering Instrument
  • The 40m small-angle neutron scattering (SANS) instrument, which makes use of long wavelength neutron of 4-8 angstrom, is one of the most powerful tools to probe nano-sized (1 - 500nm) microstructures. It covers a wide range of experiment subjects, such as polymer, micelle, colloid, complex fluids, and metallic or ceramic materials. As such, it is widely used not only in the fields of basic science about physics, chemistry, biology, and materials science and engineering, but also in applied science for industrial purposes. Due to its physical characteristics, a longer SANS instrument covers a wider range of measurable microstructures. HANARO houses a couple of SANS instruments, which are 18m and 40m long, respectively, and the 40m SANS instrument of HANARO ranks third in functional terms among all of its kind in the world. Equipped with a lens system, the minimum momentum transfer it can measure ranges from 0.0015 1/Å to 0.0007 1/Å.
