Measurements of Laser-Driven Plasma Expansion into Hohlraum-Relevant Background Gas
S. Hilsabeck, S. Dannhoff, C. A. Walsh +3
Experiments at the OMEGA EP laser facility were designed and executed to study plasma expansion into hohlraum-relevant gas fills (0.3-0.6 mg/cc of helium), providing a surrogate pl…
Evolution of laser-driven magnetic fields from proton tomography
J. Griff-McMahon, V. Valenzuela-Villaseca, C. A. Walsh +9
Self-generated magnetic fields are commonly produced in high-power laser-plasma interactions. These fields can inhibit plasma heat-flow which makes them important in inertial fusio…
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…
Kinetic Corrections to Heat-flow and Nernst advection for Laser Heated Plasmas
Chris Walsh, Mark Sherlock
Reduced models for approximating the impact of kinetic electron behavior on the transport of thermal energy and magnetic field are investigated. The thermal flux limiter has improv…
Measurements of Extended Magnetic Fields in Laser-Solid Interaction
J. Griff-McMahon, S. Malko, V. Valenzuela-Villaseca +5
Magnetic fields generated from a laser-foil interaction are measured with high fidelity using a proton radiography scheme with in situ x-ray fiducials. In contrast to prior finding…
Biermann Battery Magnetic Fields in ICF Capsules: Total Magnetic Flux Generation
Christopher Walsh, Dan Clark
This paper focuses on the process of magnetic flux generation in ICF implosions. Hot-spots are shown to be dominated by fields generated during stagnation, when the temperature and…
Updated Magnetized Transport Coefficients: Impact on Laser-Plasmas with Self-Generated or Applied Magnetic Fields
Christopher Walsh, James Sadler, Jonathan Davies
Errors in the Epperlein & Haines [PoF (1986)] transport coefficients were recently found at low electron magnetizations, with new magnetic transport coefficients proposed simultane…
