About the School
Polarized neutron measurements allow one to better understand intertwined orders in quantum materials by unambiguously distinguishing between the structural and magnetic scattering features and determining the direction of magnetic moments and their fluctuations. Furthermore, polarized neutrons also enable measurements of magnetization distribution and the determination of atomic site susceptibility tensors in a wide range of materials of fundamental and technological importance.
The main goal of the workshop is to make polarized neutrons more accessible and popular with a wider scientific community. The workshop is designed to educate the rising user community to the level where they can confidently design and propose new experiments, and independently process their data to efficiently extract the essential information.
The workshop will combine lectures and hands-on sessions introducing participants to the key concepts and applications of polarized neutron scattering techniques, including both diffraction and inelastic scattering. In addition to the lectures, the program will feature practical tutorials covering several commonly used analysis tools, including hands-on analysis of polarized diffraction data (flipping ratios and flipping-difference measurements) with CrysPy, analysis of diffuse magnetic scattering with SpinInteract, and an introduction to Mag2Pol, including hands-on analysis of unpolarized and spherical neutron polarization data.
The workshop will also highlight the polarization techniques available at ORNL by showcasing recent and planned instrumental developments in polarized neutrons at the SNS and HFIR facilities. Hands-on demonstrations are planned using pre-collected data from HYSPEC (SNS) and PTAX, POWDER, and DEMAND (HFIR), focusing on their polarization configurations as well as data processing and reduction.
The workshop is intended for graduate students, post-docs, or scientists who are wishing to extend or strengthen their expertise in neutron scattering into the realm of polarization analysis.
Workshop Location
The workshop will be held in-person at Oak Ridge National Laboratory.
