Influence of the thickness absorbing film on the PETN ignition threshold by a laser pulse [PDF]

open access: yesMATEC Web of Conferences, 2015
Numerical simulation of the PETN ignition by a film, which is heated by a laser pulse was conducted. There are shown that dependence of threshold energy of ignition of PETN by a laser pulse has a linear dependence from the thicknesses of the absorbing ...

Systematic analysis of direct-drive baseline designs for shock ignition with the Laser MégaJoule [PDF]

open access: yesEPJ Web of Conferences, 2013
We present direct-drive target design studies for the laser mégajoule using two distinct initial aspect ratios (A = 34 and A = 5). Laser pulse shapes are optimized by a random walk method and drive power variations are used to cover a wide variety of ...

Shock Ignition Laser-Plasma Interactions in Ignition-Scale Plasmas [PDF]

open access: yesPhysical Review Letters, 2021
We use a subignition scale laser, the 30 kJ Omega, and a novel shallow-cone target to study laser-plasma interactions at the ablation-plasma density scale lengths and laser intensities anticipated for direct drive shock-ignition implosions at National Ignition Facility scale.
