In order to put the results presented in this thesis into context, a short introduction is given at this point. A brief summary of the experimental results is given on page (iii). The discovery of X-ray radiation has shed light on unexplored territories in almost all disciplines of science, ranging from chemistry, biology, physics, materials science and(More)
Could massive arrays of thousands of fibre lasers be the driving force behind next-generation particle accelerators? The International Coherent Amplification Network project believes so and is currently performing a feasibility study. T he challenge of producing the next generation of particle accelerators, for both fundamental research at laboratories such(More)
We present here designs for a staged implementation of an orbiting debris remediation system comprised of a super-wide field-of-view telescope (EUSO) and a novel high efficiency fibre-based laser system (CAN). Initial proof of concept stages will operate from the International Space Station (ISS) where the EUSO telescope has been designed for operation as a(More)
ELI has been put on the European Roadmap for Research infrastructures by the European Strategy Forum on Research Infrastructures (ESFRI). It will be the first Paneuropean Infrastructure utilizing an ultra-intense laser with a peak-power of 200 PW for interaction experiments with electric field strength well above the PV/m (10<sup>15</sup> V/m ). With the(More)
We study laser-matter interactions numerically by using massively parallel computers. The ion acceleration from a double layer target driven by a laser pulse with intensities I = 10 20-10 22 W/cm 2 × (μm/λ) 2 is investigated via multi-parametric particle-in-cell (PIC) simulations. For targets over a wide range of thicknesses l and densities n e , at a given(More)
