Experimental measurement of Au M-band flux in indirectly-driven double-shell implosions
Indirectly-driven double-shell implosions are being investigated as a possible noncryogenic path to ignition on the National Ignition Facility (NIF). In recent double-shell experiments, the inner shell trajectory was shown to exhibit a strong sensitivity to the temporal history of the M-band (2-5 keV) radiation emitted from the Au hohlraum wall. A large time-dependent discrepancy was observed b...
متن کاملA Consistent Measurement-Based Picture of Core-Mix in Direct-Drive Implosions on OMEGA
68 LLE Review, Volume 86 Introduction The central goal of direct-drive implosions on the OMEGA laser1 is to validate the performance of the high-gain, directdrive ignition designs2 planned for use on the National Ignition Facility. Inferring the density, temperature, and fuel–shell mix of ignition-relevant capsule implosions is important in validating models of implosions. To this end, diagnost...
متن کاملUsing high-intensity laser-generated energetic protons to radiograph directly driven implosions.
The recent development of petawatt-class lasers with kilojoule-picosecond pulses, such as OMEGA EP [L. Waxer et al., Opt. Photonics News 16, 30 (2005)], provides a new diagnostic capability to study inertial-confinement-fusion (ICF) and high-energy-density (HED) plasmas. Specifically, petawatt OMEGA EP pulses have been used to backlight OMEGA implosions with energetic proton beams generated thr...
متن کاملSoft x-ray backlighting of cryogenic implosions using a narrowband crystal imaging system (invited).
A high-performance cryogenic DT inertial confinement fusion implosion experiment is an especially challenging backlighting configuration because of the high self-emission of the core at stagnation and the low opacity of the DT shell. High-energy petawatt lasers such as OMEGA EP promise significantly improved backlighting capabilities by generating high x-ray intensities and short emission times...
متن کاملHigh-Resolution Neutron Imaging of Laser-Imploded DT Targets
74 LLE Review, Volume 86 Imaging the neutrons produced by implosions at the National Ignition Facility1 or the Laser Mega Joule2 will require spatial resolution as good as 5 μm (Ref. 3) to identify failure mechanisms such as poor implosion symmetry or improper laser pulse shaping. An important step to achieving this goal is reported in this article. Neutron images were obtained from OMEGA implo...
