The Department of Energy's Spallation Neutron Source at Oak Ridge National Laboratory has been confirmed by the Guinness Book of World Records as the world's most powerful pulsed neutron spallation source. The SNS recently ramped up beam power to more than 300 kilowatts, producing 4.8 x 10e 16 neutrons per second. The SNS is currently sending neutrons to five instruments of an eventual 24, and its first article has been accepted in Physical Review Letters and is expected to be published soon. With an eventual beam power of 1.4 megawatts, every time the SNS ramps up, it will set a new neutron production standard.
