Dear colleagues,

We are seeking a Postdoctoral Research Associate to take on a key scientific role in shaping next-generation neutron techniques.

The goal of the project is to push the boundaries of neutron scattering by exploring cross-correlation methods for diffuse scattering with energy discrimination. You’ll work with conventional correlation choppers to study inelastic diffuse scattering, and with polarization-based chopper prototypes.

In this position you will:
(1) Perform experiments at CORELLI, the diffuse scattering instrument at SNS, for analyzing the inelastic contribution.
(2) Simulate the performance of cross-correlation methods using McStas.
(3) Develop a polarization-based correlation chopper.

Oak Ridge National Laboratory is the largest US Department of Energy science and energy laboratory, conducting basic and applied research to deliver transformative solutions to compelling problems in energy and security.  The Spallation Neutron Source (SNS) and the High-Flux Isotope Reactor (HFIR) are world-leading facilities and the scientific center of a diverse, international, and inclusive neutron scattering community (https://neutrons.ornl.gov<https://neutrons.ornl.gov/>).
