Exploration of kinetic and multiple-ion-fluids effects in D$^{3}$He and T$^{3}$He gas-filled ICF implosions using multiple nuclear reaction histories

ORAL

Abstract

To explore kinetic and multi-ion-fluid effects in D$^{3}$He and T$^{3}$He gas-filled shock-driven implosions, multiple nuclear reaction histories were measured using the upgraded Particle Temporal Diagnostic (PTD) on OMEGA. For D$^{3}$He gas-filled implosions, the relative timing of the DD and D$^{3}$He reaction histories were measured with 20 ps precision. For T$^{3}$He gas-filled implosions (with 1-2{\%} deuterium), the relative timing of the DT and D$^{3}$He reaction histories were measured with 10 ps precision. The observed differences between the reaction histories on these two OMEGA experiments are contrasted to 1-D single-ion hydro simulations for different gas-fill pressure and gas mixture. This work is supported in part by the U.S. DOE, LLNL, LLE, and NNSA SSGF.
