متن کاملFirst Observation of Cross-Beam Energy Transfer Mitigation for Direct-Drive Inertial Confinement Fusion Implosions Using Wavelength Detuning at the National Ignition Facility.
Cross-beam energy transfer (CBET) results from two-beam energy exchange via seeded stimulated Brillouin scattering, which detrimentally reduces ablation pressure and implosion velocity in direct-drive inertial confinement fusion. Mitigating CBET is demonstrated for the first time in inertial-confinement implosions at the National Ignition Facility by detuning the laser-source wavelengths (±2.3 ...
متن کاملImplosion experiments using glass ablators for direct-drive inertial confinement fusion.
Direct-drive implosions with 20-microm-thick glass shells were conducted on the Omega Laser Facility to test the performance of high-Z glass ablators for direct-drive, inertial confinement fusion. The x-ray signal caused by hot electrons generated by two-plasmon-decay instability was reduced by more than approximately 40x and hot-electron temperature by approximately 2x in the glass compared to...
متن کاملFuel Assembly for Conventional, Fast and Shock Ignition Direct-Drive Inertial Confinement Fusion
Relations between stagnation and in-flight phases are derived both analytically and numerically, for hydrodynamic variables relevant to direct-drive inertial confinement fusion implosions. Scaling laws are derived for the stagnation values of the shell density and areal density; also the hot spot pressure, temperature and areal density. Simple formulas are derived for the thermonuclear energy g...
متن کاملThe Effect of Resonance Absorption in OMEGA Direct-Drive Designs and Experiments
LLE Review, Volume 111 179 Introduction Ignition of thermonuclear fuel (DT mixture) requires a fuel areal density L0.3 g/cm2 and a hot-spot temperature L10 keV (Refs. 1 and 2). Such conditions are predicted to be achieved in direct-drive inertial confinement fusion (ICF) designs, in which a cryogenic spherical DT-ice-shell target is imploded using direct illumination by intense laser beams.3–7 ...
