X-ray optics and beam characterisation using random modulation: Experiments
Sebastien Berujon, Ruxandra Cojocaru, Pierre Piault +4
In a previous paper, we reviewed theoretically some of the available processing schemes for X-ray wavefront sensing based on random modulation. We here show experimental applicatio…
X-ray optics and beam characterization using random modulation: Theory
Sebastien Berujon, Ruxandra Cojocaru, Pierre Piault +4
X-ray near-field speckle-based phase-sensing approaches provide efficient means to characterise optical elements. Here, we present a theoretical review of several of these speckle…
Wavelength-dispersive spectroscopy in the hard x-ray regime of a heavy highly-charged ion: The 1s Lamb shift in hydrogen-like gold
T. Gassner, M. Trassinelli, R. Heß +40
Accurate spectroscopy of highly charged high-Z ions in a storage ring is demonstrated to be feasible by the use of specially adapted crystal optics. The method has been applied for…
Near-field speckle-scanning-based X-ray tomography
Sebastien Berujon, Eric Ziegler
We previously demonstrated near-field speckle scanning based x-ray imaging to be an easy-to-implement phase sensing method capable of providing both high sensitivity and high resol…
X-Ray Multimodal Tomography Using Speckle-Vector Tracking
Sebastien Berujon, Eric Ziegler
We demonstrate computerized tomography (CT) reconstructions from absorption, phase and dark-field signals obtained from scans acquired when the x-ray probe light is modulated with…
Near-field speckle-scanning-based x-ray imaging
Sebastien Berujon, Eric Ziegler
The x-ray near-field speckle-scanning concept is an approach recently introduced to obtain absorption, phase, and dark-field images of a sample. In this paper, we present ways of r…
