| Abstract Scope |
The potential of hard X-ray imaging to tackle scientific questions especially related to materials sciences can be substantially increased when the dimension time is accessible. Nowadays, unprecedented temporal resolution with hard X-ray imaging can be reached at synchrotron light sources thanks to high-speed CMOS cameras combined with indirect detection schemes and polychromatic illumination. The success of real-time X-ray imaging is underlined by numerous scientific studies: bending and welding of stainless steel require high photon energies above 100 keV but moderate acquisition rates of a few 1000 images/s. Studies of thermal abuse testing of Li-ion batteries are similar but on top need sophisticated safety installations. Visualization of laser-processing of metals is more demanding in speed (up to several 100 000 images/s). Ultimately, processes such as shock-induced cavity collapse require acquisition rates up to the MHz regime. In this presentation, we shall outline the established capabilities at synchrotron light sources. |
