High-Gain Direct-Drive Target Design for Laser Fusion (Preprint)

Authors: S E Bodner; D G Colombant; A J Schmitt; M Klapisch; NAVAL RESEARCH LAB WASHINGTON DC PLASMA PHYSICS DIV
Abstract:
A new laser fusion target concept is presented with a predicted energy gain of 125 using a 1.3 MJ KrF laser. This energy gain is sufficiently high for an economically attractive fusion reactor. X-rays from high- and low-Z materials are used in combination with a low-opacity ablator to spatially tune the isentrope, thereby providing both high fuel compression and a reduction of the ablative Rayleigh-Taylor instability.
