Structure of self-generated magnetic fields in laser-solid interaction from proton tomography
Jesse Griff-McMahon, Christopher A. Walsh, Vicente Valenzuela-Villaseca +9
Strong magnetic fields are naturally self-generated in high-power, laser-solid interactions through the Biermann-battery mechanism. This work experimentally characterizes the 3D lo…
Particle collisionality in scaled kinetic plasma simulations
S. R. Totorica, K. V. Lezhnin, W. Fox
Kinetic plasma processes, such as magnetic reconnection, collisionless shocks, and turbulence, are fundamental to the dynamics of astrophysical and laboratory plasmas. Simulating t…
Expansion-Driven Self-Magnetization of High-Energy-Density Plasmas
K. V. Lezhnin, S. R. Totorica, J. Griff-McMahon +4
Understanding plasma self-magnetization is one of the fundamental challenges in both laboratory and astrophysical plasmas. Self-magnetization can modify the plasma transport proper…
Particle-in-cell simulations of expanding high energy density plasmas with laser ray tracing
K. V. Lezhnin, S. R. Totorica, A. S. Hyder +5
The design and analysis of high energy density (HED) laser experiments typically rely on radiation hydrodynamics simulations. However, some laser-plasma interaction regimes are not…
X-ray imaging and electron temperature evolution in laser-driven magnetic reconnection experiments at the National Ignition Facility
V. Valenzuela-Villaseca, J. M. Molina, D. B. Schaeffer +13
We present results from X-ray imaging of high-aspect-ratio magnetic reconnection experiments driven at the National Ignition Facility. Two parallel, self-magnetized, elongated lase…
On parallel laser beam merger in plasmas
K. V. Lezhnin, Kenan Qu, N. J. Fisch +1
Self-focusing instability is a well-known phenomenon of nonlinear optics, which is of great importance in the field of laser-plasma interactions. Self-focusing instability leads to…
