Geometric scaling of laser-driven proton focusing from hemispherical foils
Jesse Griff-McMahon, Xavier Vaisseau, William Fox +7
We systematically characterize the focusing behavior of laser-driven proton beams from hemispherical targets of various diameters using mesh radiography. The proton focal location…
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…
Laboratory measurements of energy partitioning and anomalous electron heating in magnetized, perpendicular collisionless shocks
V. Valenzuela-Villaseca, S. Totorica, J. Griff-McMahon +6
We present laboratory results on energy partitioning from supercritical, magnetized collisionless shock experiments (, ). We report the first ob…
Reconstruction of 2D line-integrated electron density using angular filter refractometry and a fast marching Eikonal solver
Brendan McCluskey, Jesse Griff-McMahon, Daniel Haberberger +3
Refraction of an optical probe beam by a plasma can be measured with angular filter refractometry (AFR), which produces an image containing intensity contours that correspond to cu…
Record Magnetic Field Generation by Short-Pulse Laser-Driven Capacitor-Coil Targets
Lan Gao, Yang Zhang, Hantao Ji +6
Magnetic fields generated by capacitor-coil targets driven by intense short-pulse lasers have been characterized using ultrafast proton radiography. A 1-kJ, 15-ps laser at a center…
Diagnosing electric and magnetic fields in laser-driven coil targets
Yang Zhang, Lan Gao, Hantao Ji +6
Laser-driven capacitor coils are widely used to generate intense magnetic fields for various applications in high-energy-density physics research. Accurate measurement of the magne…
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…
