Demonstration of ignition-driven radiation transport through a THOR hohlraum

Ryan Lester, B. M. Haines, H. M. Johns, L. Kot et autres

The achievement of fusion ignition at the National Ignition Facility opens new opportunities for foundational studies in opacity, radiation transport, and high-flux astrophysics in regimes previously unattainable. We have succeeded in the critical enabling step of demonstrating ignition in a hohlraum modified …

Influence of the drive design on ablation front hydrodynamic instability growth in a capsule implosion at the National Ignition Facility

Alex A. Do, Seth Davidovits, Nicholas A. Aybar, Salmaan H. Baxamusa et autres

A critical aspect of inertial confinement fusion experiments lies in the control of ablation front instabilities during the implosion process. The growth of Rayleigh–Taylor and Richtmyer–Meshkov instabilities, seeded by target defects, can significantly degrade the performance of the implosion. This study explores …

First demonstration of improved yield with reduced adiabat in inertial confinement fusion implosions on the National Ignition Facility

M. Hohenberger, Daniel S. Clark, Kelli Humbird, Arthur E. Pak et autres

Laser-driven, indirect-drive inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF) recently achieved a target gain greater than one, where fusion energy output exceeds input laser energy [Abu-Shawareb et al., Phys. Rev. Lett. 132, 065102 (2024)]. Despite this milestone, gain …

Longitudinal position dependence of dark line defect growth rate in high-power diode lasers at 790 nm

Luyang Wang, R. J. Deri, William E. Fenwick, Elaine D. McVay et autres

Using a nondestructive, in situ near-infrared defect imaging technique, we obtained time-resolved images of dark line defect (DLD) growth in the cavities of several high-power 790-nm diode lasers and calculated individual DLD growth rates. A clear longitudinal spatial dependence in the DLD …

Quantification of Changes in Fill Tube Curvature During Target Assembly

Xavier Lepró, Daniel R. Malone, Chantel M. Aracne-Ruddle, Alexander Schwartz et autres

National Ignition Facility (NIF) targets used for inertial confinement fusion (ICF) experiments are precision-engineered assemblies composed of more than 100 components carefully and precisely assembled with accuracies no larger than a few micrometers in most cases. When individual components deviate from these …

Effect on compression of lowering the design adiabat in the SQ-n campaign

K. L. Baker, D. T. Casey, Daniel S. Clark, Riccardo Tommasini et autres

A set of experiments in the SQ-n campaign attempts to increase the compression in layered implosions by reducing the design adiabat from 3.0 down to ∼2.6. The experiments utilize nanocrystalline high density carbon ablators driven by a ramped laser pulse drive. Contrary …

Direct Experimental Proof of the Principal Role of Reduced High-Mode Hydrodynamic Mix in Recent Ignition Success on NIF

B. Bachmann, L. Divol, Arthur E. Pak, N. Birge et autres

This Letter details the role of reduced hydrodynamic mix in achieving the first fusion plasma to satisfy the Lawson criterion for ignition. Using novel 3D measurements of the temperature and density of the burning deuterium-tritium plasma across a series of experiments, we …

First Demonstration of Improved Fusion Yield with Increased Compression through Reduced Adiabat in Inertial Confinement Fusion Experiments at the National Ignition Facility

M. Hohenberger, Daniel S. Clark, Kelli Humbird, A. Pak et autres

Recent advancements in indirect-drive inertial confinement fusion (ICF) experiments at the National Ignition Facility (NIF) have achieved a significant milestone by demonstrating target gains greater than one, yet future applications necessitate much higher target gains. One approach to achieving improved implosion performance …

High-compression implosions based on high density carbon ablator using modified drive and capsule dopant profiles

Riccardo Tommasini, D. T. Casey, Daniel S. Clark, A. Do et autres

Laser-driven inertial fusion experiments have, for the first time, achieved a target gain greater than unity in a laboratory setting [Abu-Shawareb et al., Phys. Rev. Lett. 132, 065102 (2024)]. Despite this breakthrough, the burn-up fraction remains limited to about one-fourth of ideal …
