A cold-neutron disk-chopper spectrometer AMATERAS is under construction in Materials and Life Science Facility in J-PARC. AMATERAS is dedicated to inelastic and quisielastic neutron scattering experiments in the range of cold thermal neutron region with high-efficiency and high-resolution. The spectrometer is expected to be ready in the beginning of 2009. In this presentation, we will show current status of construction of AMATERAS and expected scientific results from the spectrometer.
