Target debris collection studies for inertial confinement fusion (ICF) experiments

Modelling debris and shrapnel generation in inertial confinement fusion experiments

Modelling and mitigation of damage are crucial for safe and economical operation of high-power laser facilities. Experiments at the National Ignition Facility use a variety of targets with a range of laser energies spanning more than two orders of magnitude (∼14 kJ to ∼1.9 MJ). Low-energy inertial confinement fusion experiments are used to study early-time x-ray load symmetry on the capsule, sh...

Production of Hollow Microspheres for Inertial Confinement Fusion Experiments

The targets used in inertial confinement fusion (ICF) experiments at the Lawrence Livermore National Laboratory are plastic capsules roughly 0.5 mm in diameter. The capsules, which typically have wall thicknesses from 20 to 60 p, must possess extraordinary symmetry and concentricity and must have surface finishes of less than 1000 A peak-to-valley variation over surface contours of from 10 to 1...

Permeation fill-tube design for inertial confinement fusion target capsules

A unique approach for permeation filling of nonpermeable inertial confinement fusion target capsules with deuterium– tritium (DT) is presented. This process uses a permeable capsule coupled into the final target capsule with a 0.03-mmdiameter fill tube. Leak free permeation filling of glow-discharge polymerization (GDP) targets using this method have been successfully demonstrated, as well as i...
