Proton probing measurements of filamentary electromagnetic structure in laser ablation of solids
J. Peebles, P. V. Heuer, D. H. Barnak +2
Proton radiography of laser direct-drive spherical implosions has shown anomalous structures that correspond to strong electric or magnetic fields extending throughout the corona.…
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…
Suppression of Electromagnetic Pulses from Laser-Target Interactions by Strong Magnetic Fields
P. V. Heuer, J. L. Peebles, J. R. Davies +12
Laser-target interactions generate intense electromagnetic pulses (EMP) that can interfere with measurements and damage equipment. In this paper we show that applying a magnetic fi…
Enhanced Hot Electron Preheat Observed in Magnetized Laser Direct-Drive Implosions
M. Cufari, M. Gatu Johnson, C. K. Li +5
Hard x-ray emission, associated with hot electron preheat, in direct-drive implosions was observed to be enhanced by a factor of by application of a T magnetic fie…
Collisionless ion-electron energy exchange in magnetized shocks
Y. Zhang, P. V. Heuer, H. Wen +7
Energy partition between ions and electrons in collisionless shocks has long been an unsolved fundamental physical problem. We show that kinetic simulations of moderate Alfvénic M…
Distortions in Charged-Particle Images of Laser Direct-Drive Inertial Confinement Fusion Implosions
P. V. Heuer, J. L. Peebles, J. Kunimune +17
Energetic charged particles generated by inertial confinement fusion (ICF) implosions encode information about the spatial morphology of the hot-spot and dense fuel during the time…
