Dr J D Cockcroft listening for atomic disintegration
Dr John D Cockcroft listening for sounds indicating atomic disintegration brought about by the bombardment with high-velocity protons of the lithium nucleus, which appears to break up into two helium nuclei. Physicists Cockcroft and E Ts Walton developed the Cockcroft-Walton accelerator to artificially accelerate atomic particles to high energies, to enable them to observe the results of splitting the atom

EDITORS COMMENTS
In this historic photograph, Dr. John Douglas Cockcroft (1897-1967) of the University of Cambridge listens intently as the sounds of atomic disintegration fill the air around him. The scene takes place in the Cavendish Laboratory, where Cockcroft, alongside his colleague Ernest Thomas Sinton Walton (1903-1995), had developed the groundbreaking Cockcroft-Walton accelerator. This apparatus, a significant advancement in the field of nuclear physics, was designed to artificially accelerate atomic particles to high energies, enabling scientists to observe the results of splitting the atom. The experiment depicted in the image involves the bombardment of a lithium nucleus with high-velocity protons. As the lithium nucleus is struck, it is believed to break up into two helium nuclei. Cockcroft and Walton were pioneers in this research, which was a crucial step towards the understanding of nuclear reactions and the development of nuclear energy. The year is 1932, and the 1930s were an exciting time for scientific discovery. The image captures the essence of the scientific spirit, with Cockcroft focused on the task at hand, surrounded by the intricate equipment and apparatus that would unlock the secrets of the atomic world. This photograph is a testament to the ingenuity and determination of these British physicists, who made significant strides in the field of nuclear physics and paved the way for future research in this area. The Cockcroft-Walton accelerator was a game-changer, opening up new possibilities for scientific exploration and leading to a deeper understanding of the fundamental building blocks of matter. This photograph serves as a reminder of the importance of curiosity, innovation, and perseverance in the pursuit of knowledge.
