Three-dimensional simulations of asymmetric implosion for cone-guided targets

Abstract

In a fast ignition scheme using a cone-guided target, the fusion target is imploded with the inserted cone. Due to the existence of the cone, asymmetric implosion is not avoidable, which has the possibility to degrade fuel compression efficiency. This paper shows how the fuel compression and temperature at the maximum compression time are affected by changing the initial opening angle and position of the cone by the use of two and three dimensional fluid code.
