land security. The research of fellow Patrick O’Malley from Rutgers University is focused on nuclear reaction studies and in particular on the question of how the stable isotope fluorine-19 is synthesized in stars when nitrogen-15 interacts with alpha particles (Figure FEL 4). Patrick measured the reaction in which nitrogen-15 interacts with deuterium, emitting a proton and thereby transferring a neutron to form nitrogen-16. He hopes to understand the destruction of nitrogen-15 from interactions with neutrons in stars. Much of his research involves the charged-particle detectors of the ORNL-Rutgers University Barrel Array (ORRUBA). He is also part of the team developing the Versatile Array of Neutron Detectors at Low Energy. Patrick spent a summer at LLNL helping to develop the neutron time projection chamber, which can be applied to locate sources of special nuclear materials that emit neutrons.
