This presentation concerns challenges in relation with planetary security (Dart Mission), spacecraft protection against debris, lightening (NDT/SHM) and life extension of structures (LSP).
In the first two cases, shocks induced by laser plasma reproduce pressure loadings involved in High Velocity Impact (HVI)(7-30 Km/s):
-to model physics,
-to select material,
-to design stacks of...
Additive Manufacturing (AM), both Laser Powder bed Fusion (LPBF) and Laser Blown Powder Directed Energy Deposition (LBP-DED) promise to produce unique, high quality components for aerospace to biomedical applications with unprecedented geometric complexity. However, the underlying physics controlling the melting, solidification, flow and other phenomena are still poorly understood. Many groups...
In the recent years we have established high energy surface sensitive X-ray diffraction as novel tool for the investigation of surfaces and nanostructures. It allows a significant acceleration of the measurements, making fast kinetic processes in in-situ and operando experiments accessible, which could not be addressed before [1-5]. These experiments allow to address fundamental processes in...
First Light Fusion (FLF) is a private UK company investigating a novel approach to inertial fusion energy (IFE), through means of hyper-velocity projectile-driven impact. Using a combination of a proprietary shock pressure amplification technology and a metallic-cased fuel-containing target, we are pursuing the goal of achieving fuel gain [1] in a quasi-spherical, volume ignition configuration...
Crystalline materials are ubiquitous. The performance of metals, ceramics and semiconductors is critical for addressing societal challenges; geoscience relates to rocks, ice and sediments while biomineralisation is an integral part of biology and Health technology. The physical and mechanical properties of such materials is often governed by their structure, which tend to be organized on many...
