Cockcroft-Walton Acceleratorš at the University of California's Los Alamos Scientific Laboratory, New Mexico (1943). John H. Manley˛, a physicist recruited into the Manhattan Project from the University of Illinois' Metallurgical Laboratory brought his accelerator to Project Ył P-Division (physics) to aid in the study of neutron scattering⁴. Later in the war, the reorganized R-Division (research) scientists employed the machine for studying neutron behavior in subcritical⁵ uranium masses.
A Cockcroft–Walton generator, or multiplier, is an electric circuit that generates a high DC voltage from a low-voltage AC input. Designed by physicists John Douglas Cockcroft and Ernest Thomas Sinton Walton to power their particle accelerator, performing the first artificial nuclear disintegration in history. They used this voltage multiplier cascade for most of their research, which in 1951 won them the Nobel Prize in Physics for "Transmutation of atomic nuclei by artificially accelerated atomic particles". The Greinacher multiplier (or doubler cascade) circuit was originally developed in 1919, by Swiss physicist Heinrich Greinacher. Cockcroft–Walton circuits are still used in modern particle accelerators. They also are used in everyday electronic devices that require high voltages, such as X-ray machines and photocopiers.
