SNS in Guinness Book of World Records

The U. S. Department of Energy's Spallation Neutron Source (SNS) at ORNL has been officially confirmed by the Guinness Book of World Records as the world's most powerful pulsed neutron spallation source. The accelerator-based SNS recently ramped up beam power to more than 300 kilowatts, producing 4.8 x 10¹⁶ neutrons per second.

The SNS is currently sending neutrons to five instruments of an eventual 24. The first scientific paper based upon research from an SNS experiment has been accepted by Physical Review Letters. Each time the SNS ramps up toward an eventual beam power of 1.4 megawatts, this incredible tool for "seeing" the positions and motions of atoms and molecules in materials will set a new neutron production standard.
