Recent Development of a 36 meter Small-Angle Neutron Scattering BATAN Spectrometer (SMARTer) in Serpong Indonesia

The 36 meter small-angle neutron scattering (SANS) spectrometer BATAN
(SMARTer) in Serpong, Indonesia has been revitalised for several years. The work on
replacing, upgrading and improving the control system and the experimental method were
conducted in order to setup the spectrometer back in operation. Two main personal computers,
one for handling and controlling the mechanical system and another one for acquiring neutron
data were employed at the spectrometer. The standard and established SANS data reduction
and analysis programs, such as GRASP and NIST Igor have been implemented to subtract the
raw scattered neutron data with the backgrounds and then analyse the corrected data. The
scattering data of ferrofluids samples, Fe3O4 and MnZnFe2O4 have been obtained using SANS
spectrometers in BATAN Serpong, Indonesia and HANARO-KAERI, Republic of Korea for
inter-laboratory comparison and investigation of proposed research interest. The results were
comparable from both scattering data analysis.
