Effect of lattice structure on hot electron transport in warm dense carbon

Summary form only given. The physics of the transport of large currents of fast (relativistic) electrons in dense matter underpins many topics in high intensity laser-solid interactions, including warm dense matter, ion acceleration and the fast ignition approach to inertial confinement fusion. The propagation of fast electrons within the target is subject to transport instabilities (e.g. resistive instabilities) which give rise to filamentation of the beam.
