QuBs Webinar | Neutron Scattering: Challenges and Opportunities
Welcome from the Chair
The opportunities offered by novel neutron sources with increased neutron flux and new optimized instrument designs at reactors and spallation sources have led to significant advances in research, ranging from elucidating the mechanisms of catalysis and ligand binding in viruses, to the determination of the numbers of nanopores in metallurgical cokes. In addition, the modernization of the sources and instruments, the development of computational tools and the complex sample environment are becoming progressively critical to success.
The future ahead of us is bright, and together we need to expand our user community in order to take advantage of these new opportunities. With this in mind, this webinar will start by providing an overview of how small-angle scattering can be applied in order to elucidate the structure of matter at the nanometer scale, followed by its recent applications and developments. Then, we will discuss the European Spallation Source, ESS, and the MIRACLES spectrometer in particular, and how these elucidate dynamic processes in a range of fields, such as life and polymer sciences, energy materials and magnetic materials. The webinar will be concluded with a discussion of how the capabilities of the Second Target Station at the Spallation Neutron Source, SNS, will complement those of the SNS First Target Station and the High Flux Isotope Reactor (HFIR).

Event Chair
The unifying theme of my research has been to understand the effects of structural changes on the physical properties principally those governing dynamics in, and induced around, a material. The sequence of topics I worked on evolved from luminescent impurities in ionic crystals to other classes of materials; ferroelectrics, colossal magnetoresistance, molecular magnets, cement paste, clays, and then to systems of biological significance. As a consequence of this development of scientific interest, I have been trained in a broad range of experimental and computational techniques, starting with op-tical spectroscopy and proceeding to Raman, infrared, elastic and inelastic neutron scattering, X-rays, and synchrotron radiation. I have sought to develop links to strong collaborators at the international level and have been engaged in promoting neutron scattering as a technique that possesses the ability to answer important questions to physicists, chemists, material scientists, and biologists.
Keynote Speakers
Small Angle Neutron Scattering, Australian Centre for Neutron Scattering, ANSTO Sydney, Australia
Small Angle Neutron Scattering, a Method to Reveal Nanometer-Range Structures Is a Wide Range of Materials: How It Works, Where to Find and What to Expect to See
Dr Anna Sokolova was a Project Leader for the design, construction and commissioning of Bilby, the time-of-flight small-angle neutron scattering instrument at the Australian Centre for Neutron Scattering, and is now an Instrument Scientist on the Bilby team. Anna is a physicist from the Small-Angle Scattering Laboratory at the Institute of Crystallography of the Russian Academy of Sciences (RAS). During her PhD and in the following years, she worked extensively in the European Molecular Biology Laboratory (EMBL, Hamburg outstation c/o Deutsche Electronen Synchrotron). She has a Masters in Physics/Biophysics from the Faculty of Physics, M V Lomonosov Moscow State University (Diploma Cum laude), and a PhD in Condensed Matter Physics from the Institute of Crystallography RAS (Moscow, Russia). Anna began work on the Bilby project in October 2009. Anna’s scientific interests have expanded extensively since her original focus on complex biological structures. In recent years, she has worked with various user groups on projects aiming to study a wide range of materials, from surfactants to vortex line lattices and skyrmions, often using complex sample environments.
The Making of MIRACLES, Building a World-Class Neutron Spectrometer at the European Spallation Source
Dr. Félix Jimenez-Villacorta currently serves as the Head of the Neutron Science and Instruments Division at ESS-Bilbao, being responsible for the design and construction of the MIRACLES spectrometer for the European Spallation Source (ESS). He has been involved in “large-facility spectroscopies” for many years, mainly in relation to synchrotron X-ray techniques and now neutron scattering, covering all aspects of research, from instrumentation to data interpretation and modeling. In the past, his main research interests were related to the determination of local order and the electronic structure of nanoscale materials and complex oxides, aiming to understand their unique (and sometimes exotic) physical properties. He has also used a combination of synchrotron X-ray and neutron scattering techniques to understand the physical properties of novel materials. At present, in addition to his duties relating to project leadership, he is also interested in the development of up-to-date neutron scientific instruments in future accelerator-driven neutron sources. As well as his professional duties as a member of the program committee of various conferences and of review panels, he has authored 90 peer-reviewed publications, three book chapters related to innovative functional nanomaterials, and recently participated in the LENS Report for “Low Energy Accelerator-driven Neutron Sources”.
Second Target Station Project, Oak Ridge National Laboratory, Oak Ridge, Tennessee, USA
The Second Target Station at the Oak Ridge National Laboratory Spallation Neutron Source - New Capabilities for Science
Dr. Ken Herwig is the Technical Director for the Oak Ridge National Laboratory (ORNL) Second Target Station (STS) Project, where he is responsible for the design, fabrication, testing, installation, and commissioning of the STS hardware. Throughout his career, he has combined his interests in understanding the structure and dynamics of molecules at interfaces, surfaces and in porous media with the development, construction and operation of new neutron scattering instrumentation and technologies. He joined ORNL in 1998 as the first instrument scientist for the Spallation Neutron Source, where he led the design and construction of the BaSiS near-backscattering neutron spectrometer, which continues to support approximately 20-30 scientific publications every year. He has served in many leadership and management roles within the Neutron Sciences Directorate at ORNL since its formation in 2006. Ken received his BS degree in Physics and Computer Science, his MS degree in Physics from Southern Illinois University Edwardsville and his PhD in Physics from the University of Illinois at Urbana-Champaign.
