Artist's concept of the cyclotron

An artist's concept of how the cyclotron particle accelerator works as a tool for cancer radiotherapy.

NRL developed the Cyclotron Particle Accelerator, which produced beams of neutrons, protons, deuterons, and helium and carbon nuclei with energies up to 80 million electron volts. These particles were used for the study of radiation damage to reactor materials, for neutron radiation therapy for cancer, for the production of radioisotopes, and for general radiation research. The NRL Cyclotron was decommissioned in 1985.
