Effect of laser pulse duration on damage to metal mirrors for laser IFE
A Grazing Incidence Metal Mirror (GIMM) is a chief candidate for beam delivery for Inertial Fusion Energy (IFE). The goal for GIMM survival is greater than 3 10 8 laser pulses with 5 J/cm 2 laser fluence normal to the incident beam. Laserinduced damage to metal mirrors is primarily a thermomechanical process. Long-term exposure leads to microstructural evolution analogous to fatigue. We have pe...
متن کاملLong-term Survival of Grazing-incidence Metal Mirrors for Laser Fusion
The grazing incidence metal mirror is a promising option for the final optic in a laser-driven inertial fusion energy power plant. It has been pursued as an alternative to multi-layer dielectric mirrors based on expectations of higher radiation damage resistance. Aluminum offers high reflectivity over a broad range of wavelengths extending deep into the ultraviolet part of the spectrum, and thu...
متن کامل14.5% near-normal incidence reflectance of Cr/Sc x-ray multilayer mirrors for the water window.
Cr/Sc multilayer mirrors, synthesized by ion-assisted magnetron sputter deposition, are proved to have a high near-normal reflectivity of R = 14.5% at a grazing angle of 87.5 degrees measured at the wavelength lambda = 3.11 nm, which is an improvement of more than 31% compared with previously published results. Elastic recoil detection analyses show that the mirrors contained as much as 15 at. ...
متن کاملUWFDM-987 Three-Dimensional Neutronics Analysis for the Final Optics of the Laser Fusion Power Reactor SIRIUS-P
A three-dimensional neutronics calculation has been performed for the final optics of the laser driven reactor SIRIUS-P. The reactor utilizes grazing incidence metallic mirrors (GIMM) and dielectric coated final focusing (FF) mirrors placed at 25 and 40 m from the target, respectively. High aspect ratio neutron traps are attached to the outer reactor containment building. The GIMM can have a li...
متن کاملDevelopment of adjustable grazing incidence optics for Generation-X
For X-ray astronomy, 0.1 arc-second imaging resolution will result in a significant advance in our understanding of the Universe. Similarly, the advent of low cost high performance X-ray mirrors will also increase the likelihood of more X-ray telescopes being funded and built. We discuss the development plans of two different types of adjustable grazing incidence optics: one being a tenth arc-s...
