OSIRIS simulation on Sequoia of the interaction of a fast-ignition-scale laser with a dense deuterium-tritium plasma. The laser field is shown in green. The blue arrows illustrate the magnetic field lines at the plasma interface. The red/yellow spheres are laser-accelerated electrons that will heat and ignite the fuel.

Star power

A visualization of a Vlasov-Poisson simulation for a bump-on-tail instability problem, where a non-equilibrium distribution of electrons drives an electrostatic wave. The image shows particle density as a function of space and velocity. (Jeffrey Hittinger, Lawrence Livermore National Laboratory.)

A passion for pressure

August 15th, 2012 Updated: August 15th, 2012

Plasmas are the purview of Livermore scientist and Computational Science Graduate Fellowship alumnus Jeffrey Hittinger. He works both sides of the fusion street – inertial confinement and magnetic confinement – while simulating aspects of these tremendously hot, fast-moving particle clouds.
