The 36-meter small-angle neutron scattering (SANS) spectrometer in BATAN Serpong which utilizes thermal neutron produced from a 30 MW of multi-purposes C. A. Siwabessy reactor (RSG-GAS) is a pinhole or conventional SANS spectrometer. The performance of the spectrometer has been improved by implementing a focusing device system, a stack of 40 MgF2 biconcave lenses, for gaining the neutron intensity upto 2.5 times and maintaining its resolution with a neutron wavelength of 5.7 angstrom. The minimum momentum transfer Q(min) of 0.002 angstrom(-1) can be achieved.
