Tilting refractive x-ray lenses for fine-tuning their focal length
Rafael Celestre, Thomas Roth, Carsten Detlefs +4
In this work, we measure and model tilted x-ray refractive lenses to investigate their effects on an x-ray beam. The modelling is benchmarked against at-wavelength metrology obtain…
Polished diamond x-ray lenses
Rafael Celestre, Sergey Antipov, Edgar Gomez +3
We present high quality bi-concave 2D focusing diamond x-ray lenses of apex-radius m produced via laser-ablation and improved via a mechanical polishing process. Both for…
Recent developments in X-ray lens modelling with SRW
Rafael Celestre, Oleg Chubar, Thomas Roth +2
The advent of 4 generation high-energy synchrotron facilities (ESRF-EBS and the planned APS-U, PETRA-IV and SPring-8 II) and free-electron lasers (Eu-XFEL and SLAC) all…
Modelling phase imperfections in compound refractive lenses
Rafael Celestre, Sebastien Berujon, Thomas Roth +2
Compound refractive lenses (CRL) offer outstanding potential for probe formation in X-ray micro- and nano-analysis as well as for imaging applications, but effective aberration-fre…
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…
A hierarchical approach for modelling X-ray beamlines. Application to a coherent beamline
Manuel Sanchez del Rio, Rafael Celestre, Mark Glass +7
We consider different approaches to simulate a modern X-ray beamline. Several methodologies with increasing complexity are applied to discuss the relevant parameters that quantify…
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…
