J. Reginald Richardson
"For his original contributions to the development of cyclotrons. These include the first experimental demonstration of phase stability, the first synchrocyclotron, and the first sector-focused cyclotron. The work is the basis of the numerous cyclotrons that have had and continue to have major impact on nuclear physics, solid state physics, chemistry, and medicine."
