AMATERAS is a cold-neutron disk-chopper spectrometer in Materials and Life science Facility in J-PARC. By combination of high-peak intensity from a H$${_2}$$-coupled moderator source and newly developed high-speed disk-choppers (the maximum revolution: 350Hz, the minimum burst time: 7.6 $$mu$$sec.) for pulse shaping and monochromating, the spectrometer realizes both high-resolution ($$Delta$$$$E/Emathrm{_i}>1%$$) and high-intensity (one order of magnitude higher than the present state-of-the-art chopper spectrometers) in the range of $$Emathrm{_i}=1sim20$$ meV, and can show sufficient performance up to $$Emathrm{_i}<$$80 meV. Construction of AMTERAS has been completed in March 2009 and the spectrometer is at commissioning phase. In this presentation, we will report the current status of AMATERAS including the first results obtained at commissioning.
