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…

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…
