Born in Todmorden, Yorkshire, John Douglas Cockcroft was educated at the Manchester College of Technology and the University of Cambridge, where he studied mathematics and electrical engineering. After graduating from Cambridge in 1924, he worked at the Cavendish Laboratory under English physicist Ernest Rutherford and collaborated with Russian physicist Peter Kapitza to design and develop powerful electromagnets. Cockcroft’s interests soon turned to nuclear physics and the challenge of accelerating atomic particles in an electric field. During the 1920s the only particles used for bombarding and breaking down the atomic nucleus (a process known as atom smashing) were alpha particles emitted by naturally radioactive elements. Rutherford had thoroughly exploited this approach, and Cockcroft believed it necessary to find particles of still higher energies to improve the process.

In 1928 Cockcroft became a Fellow at St John's College , a post he held until 1946. In 1932 Cockcroft, in collaboration with another British physicist, Ernest Walton, became the first to disintegrate an atomic nucleus with artificially accelerated subatomic particles. The two scientists used a particle accelerator that they had developed, called the Cockcroft-Walton accelerator, to bombard

Gemeinsam mit dem britischen Physiker Ernest Walton spaltete Cockcroft 1932 erstmalig einen Atomkern durch Protonenbeschuss. Die zwei Wissenschaftler verwendeten einen selbst entwickelten Teilchenbeschleuniger , den Cockcroft-Walton-Beschleuniger, um Lithium kerne mit beschleunigten Protonen zu beschieŸen. Einige Lithiumatome absorbierten ein Proton und zerfielen in zwei Helium kerne. Der Cockcroft-Walton-Beschleuniger wurde daraufhin weltweit zu experimentellen Zwecken eingesetzt. Seine Arbeit zu den Atomkernen von Lithium und Wasserstoff erwies sich als wichtig bei der Entwicklung der Wasserstoffbombe ( siehe Atomwaffen ). Cockcroft teilte sich 1951 mit Walton den Nobelpreis f¼r Physik.
