Schematic of a cryogenic layered DT ignition target showing hohlraum and capsule dimensions.
Measured laser power during peak for the four cryogenic layered experiments that were simulated.
Measured laser power (black) and input to simulation (red) after applying multipiers to match experimental data.
(a) Partially assembed shock timing target. (b) Experimentally measured shock speed versus time (black) for N110521 shock timing experiment compared to simulation without laser power adjustment (red) and with adjustment (blue).
(a) Plot of the center of mass of the remaining mass versus time for N110625 convergent ablator experiment. Black squares (data) are compared to simulations with (blue curve) and without (red curve) laser power adjustment. (b) Plot of center of mass velocity versus radius for same experiment.
Comparison of simulated and measured x-ray bangtime for simulations without multipliers (green) and with multipliers (red).
Comparison of measured Dante flux versus time to simulated flux from simulation without multipliers (red) and with multipliers (blue).
Time dependence of the P2 Legendre moment of several contours of experimental gated x-ray image of shot N110620 compared to P2 moment of 17% contour of simulated x-ray images (red pentagons). Also shown is the emission versus time, indicating that peak emission (x-ray bangtime) occurs at 22.25 ns for this experiment.
Core symmetry at time of peak x-ray emission for the June 2011 layered experiments. First row are experiment gated x-ray images. Second row are simulated x-ray images. Third row are density contour plots at same times.
Plots of (a) core density and (b) core temperature. Left side of plots is for calculation with smooth ablator and ice surfaces, while right side is for higher resolution calculation with imposed surface perturbations up to mode 60.
Comparison of experimental and simulated neutron down scattered ratios. Open squares are simulations with clean surfaces and blue diamonds are simulations with mode 60 surface perturbations.
Comparison of experimental and simulated burn-weighted ion temperatures. Open squares are simulations with clean surfaces and blue diamonds are simulations with mode 60 surface perturbations.
Comparison of experimental and simulated gamma burn widths. Open squares are simulations with clean surfaces and blue diamonds are simulations with mode 60 surface perturbations.
Comparison of experimental and simulated neutron yields (neutrons from 13–15 MeV). Open squares are simulations with clean surfaces and blue diamonds are simulations with mode 60 surface perturbations.
Summary of measured capsule performance metrics for experiment N110620 compared to simulated values from semi-empirical models of increasing complexity. YOS is measured yield over simulated yield.
