spallation neutron sources

A spallation neutron source produces neutrons by bombarding a heavy metal target, like tungsten or mercury, with high-energy protons. When the protons hit the target, they cause the nucleus of the metal atoms to become unstable and eject neutrons. These neutrons are then used for scientific research, such as studying materials at the atomic level. This process allows for the generation of intense, pulsed neutron beams, which are valuable tools in physics, chemistry, and biology for understanding the structure and behavior of various substances.
