Title: Fuel-ion diffusion in shock-driven inertial confinement fusion implosions

Abstract

The impact of fuel-ion diffusion in inertial confinement fusion implosions is assessed using nuclear reaction yield ratios and reaction histories. In T³He-gas-filled (with trace D) shock-driven implosions, the observed TT/T³He yield ratio is ~2× lower than expected from temperature scaling. In D³He-gas-filled (with trace T) shock-driven implosions, the timing of the D³He reaction history is ~50 ps earlier than those of the DT reaction histories, and average-ion hydrodynamic simulations cannot reconcile this timing difference. Both experimental observations are consistent with reduced T ions in the burn region as predicted by multi-ion diffusion theory and particle-in-cell simulations.

Probing ion species separation and ion thermal decoupling in shock-driven implosions using multiple nuclear reaction histories

Journal Article Sio, H. ; Larroche, O. ; Atzeni, S. ; ... - Physics of Plasmas

Simultaneously measured DD, DT, and D³He reaction histories are used to probe the impacts of multi-ion physics during the shock phase of inertial confinement fusion implosions. In these relatively hydrodynamiclike (burn-averaged Knudsen number ⟨N_K⟩ ~0.3) shock-driven implosions, average-ion hydrodynamic DUED simulations are able to reasonably match burnwidths, nuclear yields, and ion temperatures. However, kinetic-ion FPION simulations are able to better simulate the timing differences and time-resolved reaction rate ratios between DD, DT, and D³He reactions. FPION simulations suggest that the D³He/DT reaction rate ratio is most directly impacted by ion species separation between the ³He and T ions, whereas themore »« less

Observations of Multiple Nuclear Reaction Histories and Fuel-Ion Species Dynamics in Shock-Driven Inertial Confinement Fusion Implosions

Journal Article Sio, Hong ; Frenje, J. A. ; Le, Ari Yitzchak ; ... - Physical Review Letters

Fuel-ion species dynamics in DT³He-gas-filled Inertial Confinement Fusion implosion is quantitatively assessed for the first time using simultaneously measured D³He and DT reaction histories. Here, these reaction histories are measured with the Particle X-ray Temporal Diagnostic, which captures the relative timing between different nuclear burns with unprecedented precision (~10 ps). The observed 50±10 ps earlier D³He reaction history timing (relative to DT) cannot be explained by average-ion hydrodynamic simulations, and is attributed to fuel-ion species separation between the D, T, and ³He ions during shock convergence and rebound. At the onset of the shock burn, inferred ³He/T fuel ratio inmore »« less

Fuel–shell mix and yield degradation in kinetic shock-driven inertial confinement fusion implosions

Journal Article Sio, Hong ; Larroche, Olivier ; Bose, Arijit ; ... - Physics of Plasmas

Fuel–shell mix in kinetic plasma conditions is probed using nuclear and x-ray self-emission in shock-driven, D³He-gas-filled inertial confinement fusion implosions. As initial gas fill density decreases, measured nuclear yields and ion temperatures are lower than expected as compared to radiation-hydrodynamic simulations. Spatially and temporally resolved x-ray emissions indicate significant mixing at the fuel–shell interface in implosions with low initial gas fill density. In conclusion, this observed fuel–shell mix introduces a substantial amount of shell ions into the center of the implosion prior to and during shock flash and is the key mechanism needed in the kinetic-ion simulations to match experimentalmore » nuclear yields.« less

Kinetic mix mechanisms in shock-driven inertial confinement fusion implosions

Journal Article Rinderknecht, H. G. ; Sio, H. ; Li, C. K. ; ... - Physics of Plasmas

Shock-driven implosions of thin-shell capsules, or ''exploding pushers,'' generate low-density, high-temperature plasmas in which hydrodynamic instability growth is negligible and kinetic effects can play an important role. Data from implosions of thin deuterated-plastic shells with hydroequivalent D³He gas fills ranging from pure deuterium to pure ³He [H. G. Rinderknecht et al., Phys. Rev. Lett. 112, 135001 (2014)] were obtained to evaluate non-hydrodynamic fuel-shell mix mechanisms. Simulations of the experiments including reduced ion kinetic models support ion diffusion as an explanation for these data. Several additional kinetic mechanisms are investigated and compared to the data to determine which are important inmore »« less

First Observations of Nonhydrodynamic Mix at the Fuel-Shell Interface in Shock-Driven Inertial Confinement Implosions

Journal Article Rinderknecht, H. G. ; Sio, H. ; Li, C. K. ; ... - Physical Review Letters

A strong nonhydrodynamic mechanism generating atomic fuel-shell mix has been observed in strongly shocked inertial confinement fusion implosions of thin deuterated-plastic shells filled with ³He gas. These implosions were found to produce D³He-proton shock yields comparable to implosions of identical shells filled with a hydroequivalent 50:50 D³He gas mixture. Standard hydrodynamic mixing cannot explain this observation, as hydrodynamic modeling including mix predicts a yield an order of magnitude lower than was observed. Instead, these results can be attributed to ion diffusive mix at the fuel-shell interface.
