Abstract: Revitalization project of the thermal neutron TAS – Triple Axis Spectrometer encoded as SN1 at the Experimental Hall of G.A. Siwabessy Research Reactor of BATAN Indonesia had been performed. For evaluating purpose of the newly developed hardware and software, inelastic scattering experiments to measure lattice dynamics on Cu and Ge single crystals had been carried out. The results had been compared and in a good agreement with references. Though still not optimal, these results show that the revitalization process has been successful in restoring the function of the SN1 as an inelastic scattering instrument. This can be considered as the first important step toward the utilization of the instrument for materials characterization on lattice dynamics and magnetic excitation.
