Probing kinetic and multi-ion-fluid effects in ICF implosions using DT and D}$^{\mathrm{\mathbf{3}}}$\textbf{He reaction histories on OMEGA

To explore kinetic and multi-ion-fluid effects in D$^{\mathrm{3}}$He-gas-filled shock-driven implosions (with a trace amount of T$_{\mathrm{2}})$, D$^{\mathrm{3}}$He and DT reaction histories were measured using the upgraded Particle X-ray Temporal Diagnostic (PXTD) on OMEGA. The relative timing between the D$^{\mathrm{3}}$He and DT reaction histories was measured with 10-ps precision. The initial gas-fill density of the thin-glass targets was varied from 0.3 -- 2.2 mg/cc, spanning highly-kinetic to more hydrodynamic-like plasma conditions during shock burn. Multi-ion-fluid simulations of similar implosions show reaction histories that are quantitatively different than those from average-ion-fluid simulations, including differences in burn onset, burn width, and relative bang-time. The measured differences between the reaction histories will be contrasted to average-ion-fluid hydrodynamic simulations, as well as multi-ion-fluid and kinetic-ion simulations, using LSP.
