Materials - SNS's bright beginnings

Months into its commissioning since the first neutrons were made in late April 2006, the Spallation Neutron Source is distinguishing itself as a robust neutron source. The SNS has set records for the highest-energy proton linear accelerator in the world, for the highest number of protons in an accumulator ring and for the highest brightness, or protons per pulse onto the mercury target. Three instruments the backscattering spectrometer and the liquids and magnetism reflectometers are already receiving neutrons. In some configurations, the reflectometers are receiving neutron beams intense enough to saturate the detectors, even operating at 2 percent of the SNS's eventual 1.4 megawatts of power. All in all, these early accomplishments mark a promising beginning to decades of neutron science.
