TL;DR: Simulations indicate that with improvements in the laser-pulse focus quality, acceleration to nearly 10 GeV should be possible with the available pulse energy, and the principal physical barriers to multi-gigaelectronvolt acceleration are overcome.

TL;DR: In this paper, a new generation of laboratory diagnostics is reviewed that yield snapshots, or even movies, of laser and particle-beam-generated plasma accelerator structures based on their phase modulation or deflection of femtosecond electromagnetic or electron probe pulses.

TL;DR: In this paper, the authors adapt tomographic methods to visualize the instantaneous structure and evolution of a laser-induced object propagating through a transparent Kerr medium, reconstructing a laser pulse's diffraction, self-focusing and filamentation from phase'streaks' imprinted onto probe pulses that cross the main pulse's path simultaneously at different angles.

TL;DR: In this article, an experimental-computational study of the parameters necessary to optimize a tunable, quasi-monoenergetic, efficient, low-background Compton backscattering (CBS) x-ray source that is based on the self-aligned combination of a laser-plasma accelerator (LPA) and a plasma mirror (PM) is presented.

TL;DR: Simulations show that the nonlinear susceptibility chi(3) of the individual clusters and the coherence length of the clustered plasma medium are optimized nearly simultaneously as the clusters expand, and both contribute to the observed THG enhancement.
