___ We are using Particle-in-Cell (PIC) computer models to explore how intense photon and particle beams evolve as they propagate through plasmas. Such interactions involve relativistic and ultra-fast physics and are important in advanced Inertial Fusion, plasma-based accelerators, and plasma-based radiation concepts, as well as astrophysical plasmas. We are also modeling nonlinear laser-plasma instabilities, such as Raman scattering and two-plasmon decay, to study their importance to direct and indirect drive laser fusion. |
