TL;DR: In this article, the effects of laser polarization and wavelength on electron injection dynamics in a laser wakefield accelerator were investigated, and the authors highlighted the complex interplay between several different physical effects, including injection regimes, including above threshold ionization assisted injection, wave-breaking injection by carrier-envelope-phase effects and ionization injection.

TL;DR: Polarization sensitive emission spectroscopy measurements were reported for a petawatt laser-solid target interaction at intensities up to 5 × 10 20 ǫ W −2, using pairs of highly-orientated graphite spectrometers to resolve the sulphur Ly-α doublet as discussed by the authors.

TL;DR: Two-dimensional temperature measurements of magnetized and unmagnetized plasma experiments performed at Z relevant to the preheat stage in magnetized liner inertial fusion indicate that the magnetic field increases T_{e}, the axial extent of the laser heating, and the magnitude of the radial temperature gradients.

TL;DR: In this article, the effects of initial structure on pinch outcome were investigated using three different foil X-pinch designs, and the results from wire Xpinches with comparable mass.

TL;DR: Measurements of K-shell fluorescence lines induced by fast electrons in ramp-compressed Co targets found to increase with compression and to be consistent with predictions from self-consistent models based on density-functional theory.
