Today, neutron and X-ray beam application is well suited to reveal the structure and dynamics of materials which is the central of disciplines such as chemistry, physics, biology, engineering, materials, medicines and health sciences. A small-angle scattering (neutron, SANS and X-ray, SAXS) becomes a powerful tool for investigating and revealing the structure and dynamics, including magnetic structures of hard and soft matter in the length scale of 1 – 500 nm under variety extreme process conditions such as temperature, pressure, shear, concentration, magnetic field, etc. The 36 meter SANS spectrometer in Serpong, Indonesia has been utilized for basic research purposes on liquid, gel, powder, alloy and solid-state thin film samples. Considering the advance of nanoscience, engineering and technology is emerging rapidly, a specific mid to long-term research strategy using SANS BATAN’s spectrometer including instrument and data analysis is established and the spectrometer is widely open for research collaboration from local and regional users. Beside neutron scattering facility in Serpong Indonesia, X-ray synchrotron facility of Synchrotron Light Research Institute (SLRI) Thailand is also open for the users, especially from ASEAN countries.
