Abstract

Target interactions in Fast Ignition, a concept for igniting inertial fusion, have proven too difficult to model with standard particle-in-cell, Fokker-Planck, and/or hydrodynamics codes ¿ due to the high densities of the compressed cores and the complexities of the collisional, relativisitic electron transport initiated by laser absorption. Implicit/hybrid codes can properly treat this phenomenology, but an optimal form for these codes has not yet been developed. Moreover, their broad application has been limited, and their development and distribution has seriously lagged the more standard but less capable techniques. This project aims to further develop, refine, extend and distribute these codes throughout the Fast Ignition community. Phase I involves the development, refinement, and wide dissemination of basic implicit/hybrid simulation software. This effort will include the development of new laser absorption models, new ion transport capabilities, and the creation and distribution of a readily installable/usable code for the users. Commercial Applications and other Benefits as described by the awardee: Commercial benefits from this project would include the development of new modeling capabilities, and their dissemination to a variety of companies working to help the DOE Fast Ignition effort. Beyond the application to Fast Ignition, the refined codes should be applicable to industrial pulse power switching, lightning studies, semi-conductor design, and plasma panel optimization.
