TL;DR: Carroll et al. as mentioned in this paper used multiple laser pulses to enhance and control the properties of beams of protons accelerated in ultra-intense laser irradiation of planar foil targets.

TL;DR: In this article, the dynamics of the plasma critical density surface in an ultra-thin foil target irradiated by an ultraintense (∼6 × 10 20 Wcm − 2 ) laser pulse is investigated experimentally and via 2D particle-in-cell simulations.

TL;DR: In this paper, a differentially filtered image plate stack was used to measure the electron flux and temperature of a high intensity laser with a solid target. But the experimental results showed that the temperature of the electron distribution was relatively constant.

TL;DR: In this article, the authors used a pulse length of ~10ps to accelerate electrons to create a bright x-ray source and measured the bremsstrahlung temperature for a laser intensity from 8.5-12×1018 W/cm2.

TL;DR: In this paper, the authors investigated the transition from radiation pressure acceleration to transparency-driven processes and found that radiation pressure drives an increased expansion of the target ions within the spatial extent of the laser focal spot, which induces a radial deflection of relatively low energy sheath-accelerated protons to form an annular distribution.
