Abstract(摘要):
A radiation transport algorithm suitable for Inertial Fusion Energy (IFE) research is presented. Although it can be applied to the study of other types of IFE targets, it is specially conceived for Indirect Drive hohlraum targets, in which radiation transport plays a main role. Special attention has been paid to special IFE requirements. (i) handling of complex three-dimensional geometries, with very high contrasts in physical magnitudes, (ii) smooth transition between optically thin and optically thick regimes, both always present in hohlraum targets, and (iii) high angular resolution, essential to accurately calculate irradiation uniformity in fuel capsules. The effectiveness and precision of the algorithm is demonstrated by its application to various benchmark radiation problems.
