Realizing the full potential of ultrahigh-intensity lasers for particle and radiation generation will require multi-beam arrangements due to technology limitations. Here, we investigate how to optimize their coupling with solid targets. Experimentall

Laser-plasma x-ray sources have garnered interest from various communities due to their ability to generate high photon-energies from a small source size. The passive imaging of high energy x-rays and neutrons is also a useful diagnostic in laser-dri

By driving hot electrons between two metal plates connected by a wire loop, high power lasers can generate multi-tesla, quasi-static magnetic fields in miniature coil targets. Many experiments involving laser-coil targets rely on proton deflectometry

The production of intense X-ray and particle sources is one of the most remarkable aspects of high energy laser interaction with a solid target. Wide application of these laser-driven secondary sources requires a high yield, which is partially limite

Many of the new large European facilities that are in the process of coming online will be operating at high power and high repetition rates. The ability to operate at high repetition rates is important for studies including secondary source generati

In this paper we demonstrate the implementation of a modified uniformly redundant array (MURA) coded aperture in the x-ray imaging of high power laser produced plasma. We detail the process of design and manufacture of a self-supporting tantalum code

The ability to maximise the shot rate of large scale laser facilities is dependent on the turnaround time of the laser, diagnostics and targetry. In a move to improve the last of these, a combined target mount and carousel are being implemented on th
