History was made at Columbia

Columbia University's original cyclotron, a 10‐MeV machine that has stood in the basement of Pupin Hall for 27 years, is being dismantled and sent to the Smithsonian Institution where it will be set up as an historical exhibit. The machine was one of the first particle accelerators constructed in the United States and was used for early experiments on the fission of uranium nuclei as well as other important work.
