The saturn target for polar direct drive on the national ignition facility.
A new target design concept is proposed for direct-drive implosions while the National Ignition Facility is in its initial, indirect-drive configuration. It differs from earlier "polar-direct-drive" designs by adding a low-Z ring around the capsule equator. Refraction in the plasma formed around this ring permits time-dependent tuning of the capsule drive uniformity. An optimized simulation sho...
متن کاملPolar Direct Drive on the National Ignition Facility
212 LLE Review, Volume 96 Introduction Recent advances in direct-drive target design have enhanced target performance beyond that achieved in the original baseline ignition design.1 This substantially increases the probability of achieving moderate to high direct-drive target gain on the National Ignition Facility (NIF). The baseline direct-drive design for the NIF is itself very attractive. It...
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 کاملThe Effect of Increased Irradiation Uniformity on Imprinting by 351-nm Laser Light
LLE Review, Volume 71 101 The experimental program1 at LLE supports the national inertial confinement fusion (ICF) effort by performing experiments on OMEGA2 to investigate the requirements for attaining ignition using direct-drive targets on the National Ignition Facility. One of the primary challenges in direct-drive ICF is to minimize perturbations in the target that are created by nonunifor...

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 ...
