Abstract

<p>AMATERAS is a cold-neutron disk-chopper spectrometer newly constructed in Materials and Life Science Facility in J-PARC. By combination of high-peak intensity from a H<sub>2</sub>-coupled moderator source and high-speed disk-choppers for both pulse shaping and monochromating, the spectrometer is designed to realize both high-resolution (<i>ΔE/E</i><sub>i</sub>=1%@<i>E</i><sub>i</sub>=20meV) and high-intensity with high flexibility in cold-neutron region. Construction of AMATERAS has been completed in this spring and the spectrometer is now in commissioning phase.</p>
