Cancelled - Petascale Simulations of Laser Plasma Interactions in Higher Dimensions

In inertial confinement fusion, laser plasma interactions, where the incident laser decays into a backward going light wave and a collective mode of the plasma can reduce laser coupling by reflecting the incident laser and also accelerate electrons to pre-heat the target and degrade compression. In SRS, the instability itself is primarily one dimensional, meaning that the scattered light and the plasma waves both travel in the same direction as the laser. However, higher dimensional effects, which can be caused by laser speckle pattern used by laser smoothing schemes, external magnetic fields, can both introduce higher dimensional effects in this problem.  In my talk, I will show results from our very large scale simulations of laser plasma interactions relevant to the ongoing inertial fusion energy, and also show our current code development efforts to move our codes to the upcoming DOE exa-scale supercomputers which will enable us to perform these simulations with ever increasing realism.
