Abstract
Since more than ten years, MetalJet sources, based on liquid-metal-jet technology [1], are successfully operated in many labs over the world. By using a high-speed jet of liquid metal, instead of the traditional solid- or rotating anode, it has been demonstrated that a much higher power can be applied to the anode. Since melting of the anode is thereby no longer a problem as it is already molten, MetalJet has achieved an at least 10-100x higher brightness than the conventional solid-anode microfocus tube with the X-ray spot size range of 5- 40 µm. Key applications of the MetalJet includes X-ray diffraction and scattering, but several publications have also shown very impressive imaging results using MetalJet technology, especially imaging applications that has traditionally been limited to synchrotron studies – like ptychography [2], X-ray microscopy [3, 4] and phase-contrast imaging [5]. The transfer of these imaging technologies from the synchrotron to the home laboratory are enabled by the high brightness of the MetalJet. During 2021 the latest version of the MetalJet X-ray source, the MetalJet E1+, was introduced which can run up to 1 kW of power at a microfocus X-ray spot (30 µm). This very high power loading enables really fast X-ray imaging, and shows great promise for fast industrial X-ray inspection with high resolution. During the presentation, we will show how we achieved sub-second CT-scans of Li-ion batteries.
