Polarized Neutron Beam back at MURR after three decades

In September, 2025, Charles Majkrzak and Brian Maranville, esteemed scientists from the NIST Center for Neutron Research, visited MURR to help launch the neutron polarization capability on the GANS Neutron Reflectometer. This development is a result of our strategic partnership in neutron reflectometry and neutron scattering in general. With meticulous attention to detail, they set up the supermirrors – generously provided by NIST – and other neutron spin-flipping devices, allowing us to produce the first polarized neutron beams in nearly thirty years. The seamless commissioning is a testament to the dedication and hard work of Mizzou’s undergraduate and graduate students who put in extra hours over the past month. This cutting-edge capability will open new avenues for characterizing magnetic structures and their interplay with the chemical and physical structures of thin films at the nanometer scale. This incredible research not only deepens our understanding of fundamental science but also paves the way for advancements of national interest in quantum storage and quantum computing.
