    1939-01-02 · New York City, New York, United States

    

    Fermi arrived in New York City after leaving Italy, accepted a Columbia appointment, and entered the American scientific community. Coordinates represent New York City; the source does not identify a specific arrival terminal.

12. First U.S. fission experiment

    1939-01-25 · Pupin Hall, Columbia University, New York City, New York, United States

    Fermi participated in the first nuclear-fission experiment in the United States, conducted in Pupin Hall at Columbia University.

13. Chicago Pile-1 chain reaction

    1942-12-02 · Chicago Pile-1 site, Stagg Field, University of Chicago, Chicago, Illinois, United States

    

    Fermi led the experiment in which Chicago Pile-1 initiated the first human-made self-sustaining nuclear chain reaction. Coordinates identify the documented Chicago Pile-1 site beneath the former Stagg Field stands.

14. Argonne Woods reactor work

    1943-01-01 · Argonne Woods, Cook County, Illinois, United States

    After Chicago Pile-1 was moved to Argonne Woods, Fermi directed experiments there using the relocated reactor. The source does not date Fermi's Argonne Woods experiments more precisely than the reactor's post-1942 relocation.

15. X-10 reactor criticality

    1943-11-04 · X-10 Graphite Reactor, Oak Ridge, Tennessee, United States

    

    Fermi was present at Oak Ridge when the X-10 Graphite Reactor went critical, a milestone in the plutonium-production program.

16. Arrival at Project Y

    1944-09-01 · Los Alamos Laboratory, Los Alamos, New Mexico, United States

    

    Fermi arrived at Los Alamos and became associate director with responsibility for nuclear and theoretical physics and command of F Division. The source gives September but not the exact arrival day.

17. B Reactor fuel loading

    1944-09-01 · B Reactor, Hanford Site, Washington, United States

    Fermi inserted the first uranium fuel slug into Hanford's B Reactor, a production reactor designed to breed plutonium.

    1946-01-01 · Argonne National Laboratory, Lemont, Illinois, United States

    

    At Argonne, Fermi continued experimental physics through neutron-scattering investigations while also contributing to theoretical discussions. The source places this work in the postwar discussion following Argonne's establishment on 1 July 1946; no narrower date is supplied.

22. Recurring Los Alamos consultations

    1947-01-01 · Los Alamos National Laboratory, Los Alamos, New Mexico, United States
