A Pulsed Spallation Source for Neutron Scattering Research

A rapid-cycling 800 MeV proton synchrotron is proposed for the Rutherford Laboratory as the basis of a high intensity, pulsed, spallation neutron source (SNS) to be used for thermal neutron scattering research. The facility will be generally complementary to existing high flux sources but its effective source brightness will be at least an order of magnitude greater than these at neutron wavelengths of 1Å (~ 100 meV) and below, with an increasing advantage (100-1000 times) over the best reactor source at wavelengths approaching O.3Å (1 eV).
