Abstrakt: The recently constructed Spallation Neutron Source at the Oak Ridge National Laboratory is quickly becoming the world’s leader in neutron scattering sciences. In addition to the world’s most intense pulsed neutron source, we are continuously constructing state of the art neutron scattering instruments as well as sample environments to address today and tomorrow’s challenges in materials research. The Dynamically Polarized Sample project at the SNS is aimed at taking maximum advantage of polarized neutron scattering from polarized samples, especially biological samples that are abundant in hydrogen. Polarized neutron scattering will allow us drastically increase the signal to noise ratio in experiments such as neutron protein crystallography. The DPS project is near completion and all key components have been tested. Here we report the current status of the project. [ABSTRACT FROM AUTHOR]
