TL;DR: The Spallation Neutron Source (SNS) as discussed by the authors was designed and constructed by a collaboration of six U.S. Department of Energy national laboratories and consists of a 1 GeV linear accelerator and accumulator ring providing 1.4 MW of proton beam power in microsecond-long beam pulses to a liquid mercury target for neutron production.
