A point-to-point x-ray focusing of a spherical wave by means of cylindrically bent crystal in symmetric Bragg back diffraction geometry was investigated theoretically and simulated numerically. To separate the focal plane from an incident x-ray beam, a thin flat crystal was introduced into the setup. The effect of flat crystal diffraction on the focusing performance of the double crystal setup is discussed. It is shown that the aberration free focusing can be achieved with aspherical surface shape of the strongly bent crystal. A correction term for the surface displacement function free from spherical aberrations is derived. Thorough numerical simulations demonstrated agreement with the theoretical analysis and excellent focusing performance of 2.4 nm. Theoretically, the demonstrated result can be further improved almost by an order of magnitude.

We present a new software project aimed at development of a novel and unique software environment, suited and capable of solving a wide set of x-ray FEL optics problems. The complex of programs is based upon libraries of the Synchrotron Radiation Workshop (SRW) package. The software can be used by xFEL experimental groups for developing scientific instruments, planning experiments and processing experimental data. Specific examples of applications of FEL wavefront propagation simulations are presented: modeling of edge radiation at the soft x-ray FEL facility FLASH and of the wavefront propagation through grazing incidence optics of the hard x-ray beamlines of the European xFEL [1]. Possible ways for parallelization of calculations are also discussed.

ray-tracing algorithms are used to simulate the instrumental function of a synchrotron beamline targeted to the advanced characterization of nanocrystalline materials by powder diffraction. The characteristics of the source, a bending magnet in the present case of study, and the optics influence the instrumental profile, which is a key parameter for obtaining information on the nanostructure. We combine the SHADOW simulation with the calculation of powder diffraction profiles from standard materials, into a high-level workflow environment based on the ORANGE software, allowing us to integrate data analysis fitting software with realistic information.

We present an open source python based ray tracing tool that offers several useful features in graphical presentation, material properties, advanced calculations of synchrotron sources, implementation of diffractive and refractive elements, complex (also closed) surfaces and multiprocessing. The package has many usage examples which are supplied together with the code and visualized on its web page. We exemplify the present version by modeling (i) a curved crystal analyzer, (ii) a quarter wave plate, (iii) Bragg-Fresnel optics and (iv) multiple reflective and non-sequential optics (polycapillary). The present version implements the use of OpenCL framework that executes calculations on both CPUs and GPUs. Currently, the calculations of an undulator source on a GPU show a gain of about two orders of magnitude in computing time. The development version is successful in modelling the wavefront propagation. Two examples of diffraction on a plane mirror and a plane blazed grating are given for a beam with a finite energy band.

To achieve high resolution and sensitivity on the nanometer scale, further development of x-ray optics is required. Although ex-situ metrology provides valuable information about x-ray optics, the ultimate performance of x-ray optics is critically dependent on the exact nature of the working conditions. Therefore, it is equally important to perform in-situ metrology at the optics' operating wavelength ('at-wavelength' metrology) to optimize the performance of x-ray optics and correct and minimize the collective distortions of the upstream beamline optics, e.g. monochromator, windows, etc. Speckle-based technique has been implemented and further improved at Diamond Light Source. We have demonstrated that the angular sensitivity for measuring the slope error of an optical surface can reach an accuracy of two nanoradians. The recent development of the speckle-based at-wavelength metrology techniques will be presented. Representative examples of the applications of the speckle-based technique will also be given - including optimization of x-ray mirrors and characterization of compound refraction lenses. Such a high-precision metrology technique will be extremely beneficial for the manufacture and in-situ alignment/optimization of x-ray mirrors for next-generation synchrotron beamlines.

The upgrade of the Advanced Photon Source (APS) to a Multi-Bend Achromat (MBA) will increase the brightness of the APS by between two and three orders of magnitude. The APS upgrade (APS-U) project includes a list of feature beamlines that will take full advantage of the new machine. Many of the existing beamlines will be also upgraded to profit from this significant machine enhancement. optics simulations are essential in the design and optimization of these new and existing beamlines. In this contribution, the simulation tools used and developed at APS, ranging from analytical to numerical methods, are summarized. Three general optical layouts are compared in terms of their coherence control and focusing capabilities. The concept of zoom optics, where two sets of focusing elements (e.g., CRLs and KB mirrors) are used to provide variable beam sizes at a fixed focal plane, is optimized analytically. The effects of figure errors on the vertical spot size and on the local coherence along the vertical direction of the optimized design are investigated.

In this work, we report the advances in the development of WISER. WISER is a wave optics-based simulation library targeted at the simulation of the focusing performance of grazing x-ray optics systems, which accounts for the metrological data of figure error and roughness power spectral density. First presented in 2016 (phase-I), WISER inherits and expands the mathematical concepts of its ancestor, WISE, originally conceived for x-ray telescopes and then applied to free electron lasers. Thanks to its flexible framework, WISER easily allowed to simulate multi-element systems, as synchrotron and free electron laser beamlines. In phase-II (2020), WISER is further improved and it is delivered as fully integrable with OASYS, the graphical canvas gathering the mostly used x-ray computation tools. In the following, we will illustrate the architecture of the library and present some examples of its applications.

Monochromatic x-ray beams improve image contrast but suffer from low intensity if produced with a flat monochromator crystal. A doubly-curved crystal makes more efficient use of the source. However, the beam shape is not conducive to imaging. A combination of a bent crystal followed by a polycapillary optic can be used to monochromatize and focus x rays to a small spot to perform monochromatic x-ray imaging with good resolution. ray-tracing simulations have been developed which account for defects in both optics types. A comparison was made to measurements of focal spot sizes, angular divergence, and image quality parameters including resolution and contrast. Simulations support the experimental results that geometric blur is significantly reduced, and resolution enhanced, for magnification imaging with this optic combination.

Since 2013, OASYS (OrAnge SYnchrotron Suite) has been developed as a versatile, user-friendly and open-source graphical environment for modeling x-ray sources, optical systems, and experiments. Its concept stems from the need of modern software tools to satisfy the demand of performing more and more complex analysis and design of optical systems for 4th generation synchrotron radiation and FEL facilities. The ultimate purpose of OASYS is to integrate in a synergetic way the most powerful calculation engines available to perform virtual experiments in a synchrotron beamline. For x-ray optics, OASYS integrates different simulation strategies via the implementation of adequate simulation tools (e.g., ray tracing and wave optics packages), which communicate by sending and receiving encapsulated data. The OASYS suite has been extensively used in the optical design process for the APS-U project, and several new tools have been created to perform advanced calculations needed by the design of feature beamlines and to provide accurate specifications for the procurement of the optics.

advances at SR sources in the generation of nanofocused beams with a high degree of transverse coherence call for effective techniques to simulate the propagation of partially coherent x-ray beams through complex optical systems in order to characterize how coherence properties such as the mutual coherence function (MCF) are propagated to the exit plane [1]. Here we present an approach based on Monte Carlo sampling of the Green function. A Gauss-Shell Stochastic Source with arbitrary spatial coherence is synthesized by means of the Gaussian copula statistical tool [2]. The Green function is obtained by sampling Huygens-Fresnel waves with Monte Carlo methods and is used to propagate each source realization to the detector plane. The sampling is implemented with a modified Monte Carlo ray tracing scheme where the optical path of each generated ray is stored. Such information is then used in the summation of the generated rays at the observation plane to account for coherence properties. This approach is used to simulate simple models of propagation in free space and with reflective and refractive optics.
