Technetium: The First Element Created by a Particle Accelerator - History & Discovery
The first synthetic element to be made by a particle accelerator was Technetium (Tc).
It was created in 1937 by Carlo Perrier and Emilio Segrè at the University of California, Berkeley, using a cyclotron. They bombarded molybdenum with deuterons (nuclei of deuterium, a heavy isotope of hydrogen) to produce technetium.
