    A highly coherent 13.9 nm x-ray laser (XRL) is generated under an oscillator-amplifier configuration using a new tape target system and a driver laser system with a 0.1 Hz repetition rate. The output energy is comparable to the XRL generated with a silver-deposited slab target, and the pointing...

    Saturated outputs for the Ne-like Ge and Ni X-ray Lasers (XRLs) at 196 and 231 Å respectively are now routinely produced at RAL from long single targets. The pumping configuration of ∼ 100 ps pulses and a new simpler pump beam arrangement has been optimised with a typical XRL output of...

    Simultaneous measurements of the self-emission spectrum, the backlighting source spectrum, and the transmission spectrum in one shot, which reduce the experimental uncertainties from shot-to-shot fluctuation, are essential for precise opacity experiments. In order to achieve precise absorption...

    We demonstrate that high-Z material can be detected and located in three dimensions using radiographs formed by cosmic-ray muons. Detection of high-Z material hidden inside large volume of ordinary cargo is an important and timely task given the danger associated with illegal transport of...

    Parabolic planar compound refractive lenses (CRLs) made from glassy carbon by means of laser ablation are presented. They have radii of curvatures of 5 and 200 μm and geometric apertures of 40 and 900 μm, respectively. The numbers of biconcave elements in the CRLs were 4, 7, and 200. The...
