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…
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…
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…
Laser-driven ion and electron acceleration from near-critical density gas targets: towards high-repetition rate operation in the 1 PW, sub-100 fs laser interaction regime
V. Ospina-Bohórquez, C. Salgado-López, M. Ehret +34
Ion acceleration from gaseous targets driven by relativistic-intensity lasers was demonstrated as early as the late 90s, yet most of the experiments conducted to date have involved…
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…
Guided Electromagnetic Discharge Pulses Driven by Short Intense Laser Pulses: Characterisation and Modelling
M. Ehret, M. Bailly-Grandvaux, Ph. Korneev +13
Strong electromagnetic pulses (EMP) are generated from intense laser interactions with solid-density targets, and can be guided by the target geometry, specifically through conduct…
Proton deflectometry with in situ x-ray reference for absolute measurement of electromagnetic fields in high-energy-density plasmas
C. L. Johnson, S. Malko, W. Fox +5
We report a technique of proton deflectometry which uses a grid and an in situ reference x-ray grid image for precise measurements of magnetic fields in high-energy density plasmas…
Enhanced relativistic-electron beam collimation using two consecutive laser pulses
S. Malko, X. Vaisseau, F. Perez +8
The double laser pulse approach to relativistic electron beam (REB) collimation has been investigated at the LULI-ELFIE facility. In this scheme, the magnetic field generated by th…
