Computational Modeling in Support of National Ignition Facility Operations {*}

M. J. Shaw, R. A. Sacks, C. A. Haynam, W. H. Williams (LLNL)

Success on many of the National Ignition Facility laser^Rs missions depends on obtaining precisely specified energy waveforms from each of the 192 beams over a wide variety of pulse lengths and temporal shapes. A computerized Laser Performance Operations Model (LPOM) is being developed to guide laser setup. The LPOM automates inter-beam power balance, provides parameter checking for equipment protection and diagnostic setup, and supplies post-shot data analysis and archiving services. The LPOM relies on a NIF virtual beamline (VBL) physics model for fundamental modeling of individual beamline performance. This code integrates the simulation of amplifier pumping and energy storage, laser extraction and propagation, thermal distortions due to solid-state deformations and gas dynamics, optical aberrations and obscurations, nonlinear index-of-refraction effects, laser fluence limits, frequency conversion and focus onto target. It is a successor to several previously-separate modeling efforts in the NIF program.
