Linked neutronics and hydrodynamics calculations have been performed for X-1 targets using the radiation hydrodynamics computer code BUCKY and the neutronics code ONEDANT. Target neutronics calculations were performed taking into account the varying configuration during the burn as well as the distributed material densities and fusion neutron source profile. The energy spectrum of neutrons emitted from the target varies during the bum with a softer spectrum produced in early time intervals. Neutrons emitted from the target carry 69.22% of the fusion energy with 28.3% carried by the x-rays and debris. A small fraction of 0.03% is carried by gamma photons and 2.45% is lost in endoergic reactions. Full coupling of the neutronics and hydrodynamics calculations is essential for making consistent predictions of the partitioning of the target energy between x-rays, ion debris, neutrons, and gamma photons and an accurate estimate of the net target yield by accurately accounting for the endoergic energy losses and energy deposited by neutrons.
