John Cockcroft: Radar & Nuclear Leadership

John Cockcroft

British experimental physicist. He studied nuclear physics under the guidance of Ernest Rutherford and developed the "Cockcroft-Walton accelerator," a device that accelerates protons using high voltage, together with Ernest Walton. In 1932, using this device, he succeeded in artificially splitting lithium atomic nuclei, achieving artificial nuclear transformation. For this achievement, he was jointly awarded the Nobel Prize in Physics with Walton in 1951. During World War II, he was involved in radar development and atomic energy research, and after the war, he made significant contributions to the advancement of nuclear energy research in the United Kingdom.
