ocusing optics for neutron diffraction

A UROP project in computer simulations of neutron optics. This project is suitable for off-campus remote work. Neutron scattering is a widely used collection of techniques with applications in materials science, physics, and chemistry. These techniques are severely limited by relatively low neutron fluxes. Consequently, we are developing neutron diffractive focusing optics, which will enable very efficient neutron diffractometers. The sample is illuminated by a polychromatic neutron beam, and the multiplexing analyzer is reflecting the diffracted beam towards position-sensitive detectors. Such a multiplexing analyzer would allow for a novel way of measuring especially residual stress, in a compact high-resolution instrument, at a variety of neutron sources. The student will help developing specifications for bent Si-crystal analyzers by numerical simulations based on an existing theoretical framework, which uses matrix formalism of manipulating neutron-beam phase space. The project will require coding this analytical framework into Python or Matlab scripts and conduct simulations. Proficiency with Python or Matlab, good linear-algebra skills and interest in optical and/or nuclear experimental techniques are required. This project is suitable for being done remotely provided a student is comfortable with doing a project largely independently while relying on relatively limited if regular communications using Skype or Zoom.
