CocroftBorn in Todmanden, Yorkshire, on May 27, 1897, he entered in 1914University of ManchesterLearn mathematics, one year laterthe First World WarWhen it broke out, he had to abandon school and join the army to work as a signalman in the army.In 1918, Cochraff returned to Manchester and transferred to the Technical College to study electrical engineering. He became interested in this when he was serving in the military. He obtained a master's degree in 1922 and a bachelor's degree in mathematics in 1924 when he entered Cambridge University.Later, Cochraff stayedCavendish Lab, working with Professor Rutherford.Rutherford asked him to cooperate with Kapitza to design strong electromagnets.Later, he worked with Walton to design a voltage multiplier to accelerate protons.With this device, the first artificial transformation was made in 1932 - lithium to helium.Later, Cochraff and Walton continued to carry out atomic transformation experiments on other elements, successfully transforming elements such as boron into helium.[1]
CocroftHe was born on May 27, 1897, in Todmorton, Yorkshire.

CocroftAnd his friendsWaltonAfter repeated research, a high-voltage device capable of generating 800000 volts was built. With this device, they accelerated the protons to such a high speed that they could shoot into the atomic nucleus of light elements, thus inducing nuclear reaction.They first split the lithium nucleus into two helium nuclei by this artificial method.Furthermore, they split the nuclei of beryllium and carbon.In addition, they also found the relationship between the energy of incident particles and the energy of generated particles.The great significance of this achievement of Kocroft and Walton lies in that they changed the particles in the atomic system by means of manual control for the first time. They released powerful atomic energy by means of inducing nuclear reaction. Their experiments provided the first and most important evidence for Einstein's theory of mass energy relationship,It has played a leading role in the cause of atomic energy.Royal Swedish Academy of SciencesIt was decided on October 15, 1951 thatNobel Prize in PhysicsPresented to Professor Cocroft and Professor Walton.
