ePLAS code improvements for short pulse laser-matter interaction studies

We detail new features for ePLAS, a 2D implicit/hybrid simulation model in use for Fast Ignition. The hybrid/PIC code tracks laser light with ponderomotive force, depositing at critical into relativistic hot particle electrons, while pulling cold collisional, return-current Van Leer fluid electrons through fluid ions by means of self-consistent Implicit Moment\footnote{R. J. Mason, J. Comp. Phys. \textbf{71,} 429 (1987).} $\quad E-$ and $B-$fields. The new features include: a 1D formulation for light absorption studies with generalized \textit{E- and B-} fields, multiple laser beams, real EOS data from analytic models or the Sesame tables, K{\_}$\alpha $ imaging, generalized cold electron elevation to hots, particle ions for fast ion fusion, improved graphical options, and new Linux and Mac OS X implementations. The focus of the talk is code enhancements.
