We report on the progress of the Dynamically Polarized Sample at the Spallation Neutron Source. The SNS DPS is a collaborative project with the University of Virginia constructed for the purpose of polarized neutron scattering and diffraction. The project aims at significantly enhancing the signal-to-noise ratio by utilizing the strong spin dependent scattering cross section of hydrogen. One of the areas that are expected to benefit from this project is neutron protein crystallography, where a 10 fold gain in diffraction intensity and 10 fold reduction in incoherent background are within reach. The first step of the SNS DPS project uses a simple one Kelvin refrigerator and a 5 Tesla magnet. Our final goal is to design and build optimized setups for instruments such as the neutron protein diffractometer at the SNS (MaNDi). A brief overview of the DPS project will be given.
