Proton Radiography Inversions with Source Extraction and Comparison to Mesh Methods
J. Griff-McMahon, V. Valenzuela-Villaseca, S. Malko +4
Proton radiography is a central diagnostic technique for measuring electromagnetic (EM) fields in high-energy-density, laser-produced plasmas. In this technique, protons traverse t…

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…
