Journal ArticleDOI
Enhancement of Proton Acceleration by Hot-Electron Recirculation in Thin Foils Irradiated by Ultraintense Laser Pulses
A. J. Mackinnon,Yasuhiko Sentoku,P. K. Patel,D. W. Price,S. P. Hatchett,M. H. Key,C. Andersen,R. Snavely,R. R. Freeman +8 more
TL;DR: Observations are consistent with modeling showing an enhanced density of MeV electrons at the rear surface for the thinnest targets, which predicts an increased acceleration and higher proton energies.
Journal ArticleDOI
Numerical methods for particle simulations at extreme densities and temperatures: Weighted particles, relativistic collisions and reduced currents
Yasuhiko Sentoku,Andreas Kemp +1 more
TL;DR: This work presents a fully relativistic energy-conserving binary collision model for particle simulations with large density scale plasmas, conserving energy perfectly in each collision while momentum is conserved on the average.
Journal ArticleDOI
High energy proton acceleration in interaction of short laser pulse with dense plasma target
TL;DR: In this article, the effect of electron recirculation on the rear side sheath acceleration is discussed and it is found that the peak proton energy increases in inverse proportion to the target thickness.
Journal ArticleDOI
Laser light and hot electron micro focusing using a conical target
TL;DR: In this article, it is shown that the laser light is optically guided inside the conical target and focused at the tip of the cone, where the convergence of hot electrons to the head of a cone is observed as a consequence of the surface electron flow guided by self-generated quasistatic magnetic fields and electrostatic sheath fields.
Journal ArticleDOI
Anomalous resistivity resulting from MeV-electron transport in overdense plasma.
TL;DR: Laser produced hot electron transport in an overdense plasma is studied by three-dimensional particle-in-cell simulations, leading to a configuration which is unstable to electromagnetic Weibel and tearing instabilities.
