Laser-plasma interaction in direct-drive inertial confinement fusion
نویسندگان
چکیده
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 either a solid CH or Be ablator. These findings are shown to be consistent with experimental observations

Inverse 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. ...

LLE Review, Volume 134 112 Introduction Two-plasmon decay1–6 (TPD) is a three-wave–decay instability in which an electromagnetic (EM) wave parametrically decays into two longitudinal (Langmuir) waves. Experimentally, signatures of TPD have been observed in the ionosphere7 and in laser–plasma interaction experiments.8,9 In the context of laser fusion, TPD has been identified in both the indirect...
متن کاملOrigins and Scaling of Hot-Electron Preheat in Ignition-Scale Direct-Drive Inertial Confinement Fusion Experiments.
Planar laser-plasma interaction (LPI) experiments at the National Ignition Facility (NIF) have allowed access for the first time to regimes of electron density scale length (∼500 to 700 μm), electron temperature (∼3 to 5 keV), and laser intensity (6 to 16×10^{14} W/cm^{2}) that are relevant to direct-drive inertial confinement fusion ignition. Unlike in shorter-scale-length plasmas on OMEGA, ...
