Calculations for Indirectly Driven Be capsule Implosion Experiments at Omega
POSTER
Abstract
Beryllium (Be) ablators offer an attractive path to ignition on the National Ignition Facility (NIF). They offer better ablation rate, higher efficiency, and higher ablation velocity than the currently used CH or Diamond capsules. We have designed a capsule of Be for implosions at Omega to test our understanding of Be implosions in the foot of the anticipated NIF pulse, $\sim$ 100-110 eV for a period of 1 -2 ns drive. We calculated the emission profile, diameter, and implosion time. We will present a comparison to the completed experiments using either Be or CH ablator. We also will provide calculations of the effect of adding different amounts of an Argon dopant on the expected x-ray yield and emission shapes.
