X-ray phase-contrast imaging of micron-scale objects and features requires high spatial coherence. These highly spatially coherent x-rays can be generated at fourth generation light sources or by passing laser-produced x-rays through a narrow slit. B

The authors show that plasma electrons under petawatt laser light exhibit a random walk in a self-generated field resulting in electron confinement and efficient ion acceleration.

Our understanding of a large range of astrophysical phenomena depends on a precise knowledge of charged particle nuclear reactions that occur at very low rates, which are difficult to measure under relevant plasma conditions. Here, we describe a meth

In pump–probe experiments with an X-ray Free Electron Laser (XFEL) and a high-power optical laser, spatial overlap of the two beams must be ensured to probe a pumped area with the x-ray beam. A beam monitoring diagnostic is particularly important i

The implosion efficiency in inertial confinement fusion depends on the degree of stagnated fuel compression, density uniformity, sphericity, and minimum residual kinetic energy achieved. Compton scattering-mediated 50-200 keV x-ray radiographs of ind

We present a study on the impact of a gas atmosphere on the collision of two counterpropagating plasmas (gold and carbon). Imaging optical Thomson scattering data of the plasma collision with and without helium in between have been obtained at the Om

1. Introduction One of the most studied short-pulse laser-driven particle acceleration schemes is proton generation via the target-normal sheath-acceleration[1] mechanism, where hundreds of experiments[2] have been performed at facilities worldwide.

Compound parabolic concentrator (CPC) cone targets have been shown to produce increased MeV photons on the NIF-ARC by 10× over flat targets. Multiple x-ray frames can potentially be generated by firing the NIF-ARC's beamlets into distinct cone targe

We study the interaction of intense multi-picosecond laser pulses with arrays of carbon wires attached to solid substrates. We find that laser absorption in wire arrays resembles that in flat targets with very large uniform plasma density gradients.
