Abstract Scope |
The Forming and Shaping Technology (FAST) beamline at the Cornell High Energy Synchrotron Source (CHESS) provides in-situ, time-resolved x-ray imaging and diffraction for investigating the performance and processing of structural materials. In-situ x-ray phase-contrast radiography of deformation phenomena such as crack propagation during high strain rate deformation or shockwave-particle interactions provide a real-time through-thickness picture of the damage process, something only attainable using the penetrative power of x-rays. This work focuses on the developments on both the x-ray source and x-ray photon detection fronts, at the FAST beamline, to enable x-ray phase contrast radiography at 5MHz frame rates, with ~100ps long x-ray pulses from the stroboscopic synchrotron source. Aliasing between the stroboscopic source and scintillator coupled x-ray detectors is discussed, using the Shimadzu HPV-X2 as an example. Finally, steps to overcome the aliasing effect by modifying the stroboscopic nature of the synchrotron to suit specific experiments and detectors are addressed. |
