Project description
Imaging dynamic processes in higher resolution with 4D X-ray microscopy
Efficient diagnostic tools for observing ultrafast phenomena at small scales for modern applications such as additive manufacturing are lacking. The EU-funded MHz-TOMOSCOPY project aims to set a new record in 4D X-ray microscopy, achieving higher spatial and temporal resolutions. Using high-brilliance X-ray sources and multiple X-ray probes, researchers aspire to visualise and characterise dynamics reaching velocities up to some km/s for the first time in the micrometre scale. 4D imaging of opaque samples at MHz rates will open up new windows of understanding in many fields, especially where ultrafast phenomena have been left to simulations and speculations.
Objective
Modern enabling technologies, such as additive manufacturing or cavitation peening used in the aerospace and automotive industries, suffer from a lack of diagnostic tools. To date, one cannot provide relevant volumetric information about the fast processes involved. The realization of this project will break the current limits in fast, 4D X-ray microscopy by three orders of magnitude. It will be possible to visualize and characterize dynamics reaching velocities up to ~km/s for the first time with micron-scale resolutions. Instead of sample rotation, we will generate multiple X-ray probes and virtually rotate them around the sample to obtain with a single exposure multiple angular views simultaneously. Using modern X-ray sources with very high brilliance, each such 3D frame may be sampled at kHz rates at synchrotrons and even MHz rates at X-ray free-electron laser sources. This will unlock access to 4D observation of processes with velocities never before possible. 4D imaging of opaque samples at MHz rates enables insights across a range of sectors and industries. In cavitation peening, an industrially relevant phenomenon for aerospace and new materials, we have no volumetric information, due to its high speed. This breakthrough will be achieved by the construction of a prototype that will demonstrate MHz rate tomoscopy at the European XFEL, taking advantage of world-unique European laboratories for the benefit of industry. Observing MHz-fast phenomena in opaque samples enables an entirely new branch of research, with possibilities for all sectors where such fast phenomena has, to date, been left to simulations and speculations. For industry and society, it would open new possibilities in the development and management of several techniques, including laser driven additive manufacturing, shock waves, fractures, evaporation, light alloy metallurgy, fast fluid dynamics, and cavitation phenomena.
