dc.description.abstractThe presentation will be focused on the unique features and performance characteristics of the new BILBY SANS instrument. The inspiration for BILBY is the D33 instrument located at the ILL [2]. Similar to D33, BILBY exploits neutron time-of-flight (ToF) to extend the measurable Q-range, over and above what is possible on a conventional reactor-based monochromatic SANS instrument. The main feature of the ToF mode is a flexibility in the choice of wavelength resolution starting from value about 3%. Also, BILBY design allows to operate it in the monochromatic mode at a standard wavelength resolution of 10%. Two arrays of position sensitive detectors in combination with utilizing of wide wavelength range provide capability to collect scattering data of wide angular range without changing experimental set-up (standard dynamic range at ToF mode is in order of six hundred; the highest accessible angle ~1.8Å-1). Data reduction concept implemented in Mantid software [3] will be presented. ToF mode has enormous advantages at a price of several complexities. Special attention will be brought to the challenges of using ToF mode for study hard matter samples and samples with high hydrogen content. Also, main performance parameters and their comparison with those of the leading world instrument will be shown.en_AU
