Early-Time HANE Simulation and Experiment

Abstract

This report focuses on the NRL laser facility, new experimental results from it, and computer models for the experiments. It makes a substantial contribution to the understanding of collisionless coupling, both with and without magnetic fields. It remains very important to stay focused on the critical question of early-time debris-air coupling related to late-time spatial structures. Cataloging collisionless phenomena is recommended for consideration while continuing to perform collisional experiments. Early-time shadowgraphy with radiating ambient gasses should be considered. While aneurysms remain an interesting phenomena, they may not be related to the primary HANEs explorations. Consideration is recommended of blunt-ended probes as a supplement to spherical obstacles in plasma flow experiments. The use of a fast multichannel device is recommended after the spectrometer and the consideration of two-color interferometry as diagnostic tools. The purposeful exploration of target variation is recommended through the deliberate use of spherical or hemispherical and other non-flat targets of planned inhomogeneity. Increased correspondence between experimental simulations and the HANE data base is recommended. Two-dimensional modeling efforts are anticipated and the consideration is suggested of special purpose machines or parallel machines before investing in more conventional computers for such modeling.
