Automating neutron experiments with AI

Oak Ridge National Laboratory researchers are developing a first-of-its-kind artificial intelligence device for neutron scattering called Hyperspectral Computed Tomography, or HyperCT. The fully automated, AI-driven platform can rotate a sample in almost any direction, eliminating the need for human intervention and significantly reducing lengthy experiment times.

The design enables scientists using neutron scattering, a technique that measures atoms inside materials, to complete characterizations of samples without pauses for adjustments. The AI software determines the optimal angles to measure based on a sample’s shape, greatly reducing the amount of unnecessary data that could slow down experimental results.

“With only a few input parameters, HyperCT will give us more accurate data roughly four times faster than conventional methods,” said ORNL’s Hassina Bilheux.
