MODELING LASER–PLASMA INTERACTION PHYSICS UNDER DIRECT-DRIVE INERTIAL CONFINEMENT FUSION CONDITIONS Introduction
Introduction Laser–plasma interaction (LPI) processes taking place in indirectand direct-drive targets differ significantly in several ways. Plasma electron densities ne in hohlraum targets are typically a few percent of the critical density n m e c e = ω π 0 2 2 4 , so that the main instability mechanisms are stimulated Raman and stimulated Brillouin scattering (SRS and SBS, respectively), whi...
متن کاملImpeding hohlraum plasma stagnation in inertial-confinement fusion.
This Letter reports the first time-gated proton radiography of the spatial structure and temporal evolution of how the fill gas compresses the wall blowoff, inhibits plasma jet formation, and impedes plasma stagnation in the hohlraum interior. The potential roles of spontaneously generated electric and magnetic fields in the hohlraum dynamics and capsule implosion are discussed. It is shown tha...
متن کاملLaser-plasma interaction in direct-drive inertial confinement fusion
Hot electrons generated by the two-plasmon–decay instability in direct-drive targets are a preheat concern. A mitigation strategy that employs a layered ablator [V. N. Goncharov et al., Phys. Plasmas 21, 056315 (2014)] has been investigated both numerically and experimentally. The numerical simulations described here predict reduced hot-electron production compared with similar targets using ei...
متن کاملInverse Braking Radiation and Resonance Absorption in Corona Plasmas of Inertial Confinement Fusion
Abstract: In this paper, combining the Maxwell equations with the electron balanceequation, we obtain the inverse braking radiation absorption coefficient in a laser fusioncorona plasma. For a fixed plasma temperature, variations of the absorption coefficientversus the penetration depth into the plasma are illustrated numerically for differentvalues of laser wavelength. ...
متن کاملContributions on Laser Driven Inertial Confinement Fusion
The following modified preprint of a chapter in the forthcoming book by Guillermo Velarde and Natividad Carpintero Santamaria Inertial Confinement Nuclear Fusion: A Historical Approach by its Pioneers with personal comments is presented here as an example about the long years difficult developments towards the aim for producing unlimited, safe and clean nuclear energy in the same way as it is t...
