ABSTRACT
Small-angle Neutron Scattering (SANS) is a powerful technique for probing the inhomogeneous structure and orientation of materials on a scale of up to several hundred nanometers. A key advantage of neutron scattering is its sensitivity to isotopes, particularly the significant contrast between hydrogen and deuterium. This makes SANS an indispensable tool for investigating the structure and dynamics of hydrogen-rich materials, such as polymers and biological macromolecules. The SANS instrument at the China Spallation Neutron Source (CSNS) has been open to the user community since 2018 and has successfully facilitated nearly 400 user projects, yielding a growing number of high-quality scientific outcomes. This presentation will introduce the fundamental principles of the SANS technique and its appliation in various fields. Furthermore, it will provide a brief overview of the unique characteristics of the SANS instrument at CSNS and offer practical guidance on the process of applying for beamtime and conducting experiments.
BIOGRAPHY
Dr. Hanqiu Jiang is an associate professor and instrument scientist for the small-angle neutron scattering (SANS) instrument at the China Spallation Neutron Source (CSNS). She earned her Ph.D. in materials science from the University of Cincinnati in 2019, where her doctoral research focused on the structural characterization of wormlike micelles using SANS and other small-angle scattering techniques.
Immediately following her doctoral studies in 2019, Dr. Jiang joined the SANS group at CSNS. She is in charge of the development and maintenance of the instrument's data reduction framework. She is also primarily responsible for providing expert support to users from diverse backgrounds—including polymer science, biology, shales, alloys, et al. Her work on user support, which covers experiment design, sample preparation, data reduction, and analysis, has resulted in over 40 collaborative, peer-reviewed publications.
