DESCRIPTION:Speakers: Kathleen Wood (Australian Nuclear Science and Techno
 logy Organisation)\nQuokka was the first SANS instrument to be in operatio
 n at the Australian research reactor\, OPAL [1]. It is a 40 m pinhole inst
 rument operating with a neutron velocity selector\, an adjustable collimat
 ion system providing source-sample distances of up to 20 m and a two dimen
 sional 1 m squared position-sensitive state-of-the-art detector\, capable 
 of measuring neutrons scattered from the sample over a secondary flight pa
 th of up to 20 m. Also offering incident beam polarization and analysis ca
 pability as well as lens focusing optics\, Quokka has been designed as a g
 eneral purpose SANS instrument with a large sample area\, capable of accom
 modating a variety of sample environments. Some of these sample environmen
 ts are\, a Rapid Heat Quench Cell enabling a sample to be studied in situ 
 following a thermal shock (-120°C to 220°C)\; The neutron Rapid Visco An
 alyser (nRVA) which enables SANS to be measured simultaneously with viscos
 ity via an RVA – an instrument widely used within the food industry\; In
 -situ Differential Scanning Calorimetry (DSC)\; A stopped flow cell\, and 
 RheoSANS.\nIn early 2021 Quokka achieved the milestone of 200 peer-reviewe
 d publications in a variety of research fields. Here we cover some of the 
 research highlights along with Quokka’s performance and operation.\n\n[1
