We aim at constructing a polarisation analysis neutron spectrometer at Materials and Life Science Experimental Facility (MLF) of Japan Proton Accelerator Research Complex (J-PARC) based on a collaboration of KEK and Tohoku Univ. The proposed instrument, named POLANO, is designed as a compact chopper spectrometer with a rotary detector bank ( = 17.5 m, = 2.5 m). At the first phase of the project, we will concentrate the 30 meV region using a fan type bender supermirror spin analyser because rich scientific targets in basic and application materials science exist in this region. In the second phase, we will try to install a He spin filter analyser for the 100 meV region. This project passed in the final board of J-PARC on SEP-2011, and the construction has been authorized already.
