AMATERAS is a cold-neutron disk-chopper spectrometer installed at beam-line No. 14 at Materials and Life Science Experimental Facility (MLF) at J-PARC. Owing to the use of newly developed high-speed disk choppers and the high peak intensity from the coupled moderator source of MLF, the AMATERAS design to realize high-intensity and fine and flexible energy resolution measurements in quasielastic and inelastic neutron scattering experiments in cold and sub-thermal neutron energy region. In this presentation, we will show the current status of AMATEAS including the results of performance tests and some of examples of scientific outputs.
