Spallation Neutron Source SNS produces neutrons with an accelerator-based system that delivers short (microsecond) proton pulses to a steel target filled with liquid mercury through a process called spallation.

Spallation neutron source (SNS) is an accelerator complex designed to deliver 1.5 MW of pulsed beam power at a repetition rate of 60 Hz. The accelerator complex consists of the ion source...

Production of Spallation Neutrons. A schematic diagram of a pulsed source (based on ISIS, UK) is shown below: Pulsed neutron sources have some similarities to synchrotron sources in that both accelerate particles in a ring, but there the similarity ends.

The Spallation Neutron Source [1,2], located in Oak Ridge, TN, is a next-generation neutron-scattering facility now under construction by a partnership of six national laboratories. The facility is composed of a high-power particle-accelerator system, a liquid-mercury target-moderator system, and a suite of world-class scientific instruments.

Not unlike reactor-based neutrons, spallation neutrons are moderated by either water or a liquid hydrogen source, giving rise to thermal or cold neutrons, respectively. The SNS chose mercury as...

At present mainly two types of neutron sources arc in usc for neutron scattering research, the steady state source based on fission reactors using highly enriched U235 fuel and the acce lerator based pulsed source, where the neutrons arc produced by spallation of a nonfissile target.

The Spallation Neutron Source (SNS) is an accelerator-based neutron source facility in the U.S. that provides the most intense pulsed neutron beams in the world for scientific research and industrial development. [1]

The Spallation Neutron Source (SNS) at ORNL provides the most intense, pulsed accelerator-based neutron beams in the world, while the High Flux Isotope Reactor (HFIR) is the most powerful reactor-based source of neutrons for research in

SNS delivers short pulses of protons—60 times a second—to a target system where neutrons are produced through a process called spallation. Why neutrons? Because neutrons have no electrical charge, they can easily pass through a sample of material without harming it, revealing information about the material’s structure and properties.
