Dr. Kirk Flippo received his Ph.D. in Nuclear Engineering from the University of Michigan, studying under Professor Don Umstadter (currently at the University of Nebraska), in 2003. His Ph.D work concerned the interaction of high-intensity short-pulse laser interactions with matter in both the underdense and overdense regimes. His thesis work concerned the differences in ion beam quality from targets of varying conductivities; differentiating between the front and back surface acceleration mechanisms; using these beams to produce nuclear isotopes and proof-of-principle hadron therapy experiments. At Michigan he gained extensive knowledge of dense plasmas, laser-matter interactions and instabilities, particle stopping, nuclear reactions, and self-modulated wake field produced electron beams. Part of his thesis work on solid targets was basis of the seminal 2000 Phys. Rev. Lett. [Macksimchuk, 2000] paper on ion acceleration from solid targets. In March of 2004 he joined Los Alamos National Laboratory in the Plasma Physics group (P-24) as a Post-doc to begin work on a project where he studied the generation and stopping of heavy ions in plasmas. This work culminated in the production of the world’s first mono-energetic (10% ΔE) ion beam from short-pulse laser-matter interactions. He is currently working on laser plasma instabilities in the underdense regime relevant for ignition conditions on the NIF, and high-current, high-energy, laser-driven ion accelerators with applications in warm dense matter, boost physics, and fast ignition fusion. He is the Principal Investigator on an experiment using novel hollow micro cone targets, which have produced the highest energy laser-accelerated protons of any research group to date (67.5 MeV), and he has produced protons beams with the highest current and efficiency for a given laser energy.
