TL;DR: The spectral features provide evidence of a multispecies scenario of radiation pressure acceleration in the light sail mode and indicates that monoenergetic peaks with more than 100 MeV/nucleon are obtainable with moderate improvements of the target and laser characteristics, which are within reach of ongoing technical developments.

TL;DR: The interaction of a 3x10 W/cm;{2} laser pulse with a metallic wire has been investigated using proton radiography and the transient field measured is interpreted as a charge-neutralizing disturbance propagated away from the interaction region as a result of the permanent loss of a small fraction of the laser-accelerated hot electron population to vacuum.

TL;DR: The relativistic electron beam is shown to be confined to an area of the order of the core diameter (50 μm), which has the potential to substantially enhance the coupling efficiency of electrons to the compressed fusion fuel in the Fast Ignitor fusion in full-scale fusion experiments.

TL;DR: Particle-in-cell simulations indicate that a multitude of tubelike filamentary structures observed to form behind the front of a plasma created by irradiating solid-density wire targets with a high-intensity laser pulse can be attributed to a Weibel instability driven by a thermal anisotropy of the electron population.
