Integrated Analysis of Nuclear Measurements from the Target-Offset Campaign on OMEGA

ORAL

Abstract

A series of room-temperature and cryogenic experiments with intentional target offsets have been performed on OMEGA to maximize the nuclear signatures of asymmetric compression of the hot spot. Introducing an intentional target offset seeds low-mode asymmetries that generate flows within the hot spot and asymmetries in the shell areal density. Flows within the hot spot manifest as shifts and non-thermal broadening in the neutron energy spectrum emitted by the hot spot, while areal-density nonuniformities lead to variations in the scattered neutron energy spectrum. Measurements of the inferred hot‑spot motion, ion temperature, and shell areal density along multiple lines of sight are presented and compared with 2-D radiation–hydrodynamic simulations including the effect of target offset as well as cross-beam energy transfer.
