A new time of flight inelastic neutron scattering instrument, Pelican, is currently under construction at the OPAL research reactor at ANSTO. The instrument is designed to be of broad use with applications ranging from superconductivity and condensed matter physics, through to polymer science and soft condensed matter. The use of large PSD detectors (Fig 1) will allow a large fraction of reciprocal space to be measured simultaneously allowing the study of single crystals as well as powders and liquids. The instrument is also designed to allow polarization analysis with a large detector coverage. A supermirror transition polarizer will be utilized, while the neutron polarization will be determined using 3He and a PASTIS coil setup [1]. The utilization of polarization analysis further extends the potential use of Pelican to allow the study of magnetic excitations in a wide range of materials. In the current poster I will present the scientific background behind the instrument along with potential scientific applications.
