Abstract

Recently a new fast ignitor concept has been proposed by Velarde et al. (2003) that uses only one energy drive. In this concept, the ignition is induced by the collision of high velocity matter accelerated inside a conical guide. The first model used a jet produced by illuminating a conical shape with a laser or X-rays. On the other hand, in the shell impact concept, the compressed deuterium-tritium fuel is ignited by a separately imploded shell traveling in a guiding cone. In this article, we will study the first design, jet driven concept that have been developed during this year. We use for this work the Arwen code (Ogando & Velarde, 2001; Rendleman et al., 2000), with two-dimensional (2D) multi-group radiation transport. The main parameter is to analyze the specific power transmitted to the target during the collision. Problems with the designs are the guide integrity during the collapse, the radiation preheating, and the average efficiency of the process, etc. which we will address as well.
