Abstract
In inertial fusion energy (IFE) research, a considerable attention has recently been focused on the issue of large target fabrication for MJ-class laser facilities. The ignition and high-gain target designs require a condensed uniform layer of hydrogen fuel on the inside of a spherical shell. In this report, we discuss the current status and further trends in the area of developing the layering techniques intended to produce ignition, and layering techniques proposed to high repetition rate and mass production of IFE targets.
Highlights
Controlled inertial fusion energy (IFE) research is aimed at developing a new powerful energy source which is safe, environment- friendly and cost-effective
In this Review we discussed the state of the art, and described recent developments and strategies in the area of high repetition rate and mass production of the cryogenic targets for laser IFE
Special emphases were focused on principal changes that must be made in technology development in the area of target fabrication and delivery
Summary
Controlled inertial fusion energy (IFE) research is aimed at developing a new powerful energy source which is safe, environment- friendly and cost-effective. (4) In addition, the single crystals with anisotropic HCP structures formed by the beta-layering technique in terms of current and future applications (e.g., in reactor-scaled targets) generate serious problems relevant to the target quality survival under different environmental effects. This concerns the survivability of fuel layers with different anisotropy under conditions of the thermal and mechanical overloads during target delivery. We discuss the issues concerning the evaluation and recommendations of scalable techniques for mass production of the foam shells and the cryogenic targets
