| Popis: | A new generation of cameras has made ultra-high-speed x-ray imaging at synchrotron light sources a reality, revealing never-before-seen details of sub-surface transient phenomena. We introduce a versatile indirect imaging system capable of capturing—for the first time—hundreds of sequential x-ray pulses in 16-bunch mode at the European Synchrotron Radiation Facility, recording at 5.68 Mfps over dozens of microseconds, with an effective exposure of 100 ps. The versatile multiplex camera construction of the system allows for various arrangements, including different scintillator configurations, and simultaneous imaging with different resolutions and regions of interest. Image results from a gas gun impact experiment, in which an additive manufactured aluminum lattice was dynamically compressed, is presented as a demonstration of the system’s capabilities. |
