NIST’s INFER project aims to develop far field neutron interferometers for multi-scale imaging and precision measurements of fundamental constants. The project seeks to create tools that can study hierarchical systems across multiple length scales, from nanometers to kilometers. INFER will use a two-grating far-field neutron interferometer to create phase images and measure pair correlation functions. The project also aims to measure the local gravitational field and make precision measurements of Newton’s gravitational constant. The INFER collaboration includes researchers from NIST, University of Maryland, Louisiana State University, and University of Waterloo.
