In technology, a cyclotron is a type of particle accelerator. In physics, the cyclotron frequency or gyrofrequency is the frequency of a charged particle moving perpendicularly to the direction of a uniform magnetic field, i.e. a magnetic field of constant magnitude and direction...

. Dunning wanted a more powerful neutron source and the cyclotron appeared as an attractive tool to achieve this end. During 1935 and 1936, he was able to construct a cyclotron using many salvaged parts to reduce costs and funding from industrial and private donations. The cyclotron design and building project began as Anderson was completing his engineering degree. At the suggestion of Professor Dana Mitchell, Dunning offered Anderson a teaching assistant position if he would also help with the design and building of the cyclotron. While working on his doctorate, Anderson made two major contributions to the project. The first was to design a high frequency filament supply, rather than the commonly used direct current version. This fostered longer filament life in the high magnetic field environment of a cyclotron. The second and more important contribution was the use of a pair of concentric lines to feed the cyclotron dees (cyclotron electrodes in the shape of a “D”), rather than the usual induction system. This refinement resulted in greater cyclotron efficiency and thereafter became a regular feature in cyclotron design. Others assisting Anderson in the construction of the cyclotron were Eugene T.

, two University of Columbia physicists working at Princeton, heard the news and carried it back to Columbia. Rabi said he told Fermi; Fermi gave credit to Lamb. Bohr soon afterwards went from Princeton to Columbia to see Fermi. Not finding Fermi in his office, Bohr went down to the cyclotron area and found Anderson. Bohr grabbed him by the shoulder and said: “Young man, let me explain to you about something new and exciting in physics.” It was clear to a number of scientists at Columbia that they should try to detect the energy released in the nuclear fission of uranium from neutron bombardment. On January 25, 1939, Anderson was a member of the experimental team at Columbia University which conducted the first nuclear fission experiment in the United States, which was conducted in the basement of Pupin Hall

Fermi had only arrived at Columbia a short time before this historic demonstration. This bringing together of Fermi and Anderson resulted in a rewarding relationship lasting until the death of Fermi in 1954. Fermi and Anderson conducted a series of experiments at Columbia on the slowing down of neutrons in graphite, absorption and reflection of slow neutrons by numerous relevant materials, fissioning of uranium, and preliminary experiments using a lattice of uranium in graphite. A paper based on Anderson’s PhD thesis, Resonance Capture of Neutrons by Uranium, for security reasons, was not published until 10 years later.
