DESCRIPTION:Speakers: Anna Sokolova (Dr)\, Andrew Whitten (ANSTO)\, Lilian
 a de Campo (ANSTO)\, Chun-Ming Wu (NSRRC)\nANSTO for more than ten years s
 uccessfully operates the Small Angle Neutron Scattering (SANS) instrument 
 Quokka[1] and in 2016 commenced the user operation of the second SANS inst
 rument\, Bilby[2]. The Ultra-small angle scattering instrument Kookaburra[
 3] is completing the set of the SANS instruments at ANSTO.\n\nBilby exploi
 ts neutron Time-of-Flight (ToF) to extend the simultaneous measurable Q-ra
 nge over and above what is possible on a conventional reactor-based monoch
 romatic SANS instrument. In ToF mode\, choppers are used to create neutron
  pulses comprising wavelengths between 2 and 20 Å of variable wavelength 
 resolution (~3% ‒ 30%). In addition\, Bilby can operate in monochromatic
  mode using a velocity selector.\n\nTwo arrays of position sensitive detec
 tors in combination with utilizing the wide wavelength range provide the c
 apability to collect scattering data of a wide simultaneous angular range 
 without changing the experimental set-up (maximum accessible Q on the inst
 rument is 0.001-1.8Å-1). \n\nAdditionally\, there is a range of sample en
 vironment available allowing to change sample conditions in situ\, which i
 s priceless for the study of a wide variety of samples ranging from colloi
 ds and hierarchical materials to metals. Here we present some recent examp
 les. \n\n\n\nReferences\n\n1.	K. Wood et al\, QUOKKA\, the pinhole small-a
