Use of hohlraum liners to improve hohlraum performance

ORAL

Abstract

Hohlraum liners can be used to improve many aspects in hohlraum physics. They can be used to modify the x-ray spectrum, thereby reducing the symmetry swings induced by m-band driven primarily from the outer beam spots. Simulations indicate that reducing the level of x rays between 1.8 to 4 keV can allow the reduction or elimination of dopant in ICF capsules, thereby reducing the ablation front growth factors and leading to a more stable implosion. Liners can be used to introduce low Z species into the wall to alter the gain of LPI. At the lowest densities they can be used to greatly reduce wall motion. Diminished wall motion would reduce symmetry swings and allow some ICF platforms to operate at lower gas fill densities, thereby reducing LPI and CBET. All of these are beneficial to the performance of the hohlraum. In this presentation experimental results from liner experiments conducted on the NIF will be presented.
