Detection of heavy elements, such metals, in macromolecular crystallography (MX) examples by X-ray fluorescence is a function traditionally covered at synchrotron MX beamlines by silicon drift detectors, which may not be used at X-ray free-electron lasers due to the really quick duration associated with X-ray pulses. Right here it is shown that the hybrid pixel charge-integrating sensor JUNGFRAU can meet this function when operating in a low-flux regime. The feasibility of accurate place dedication of micrometre-sized material markings is also shown, to be utilized as fiducials for offline prelocation in serial crystallography experiments, based on the specific fluorescence signal measured with JUNGFRAU, both at the synchrotron and also at SwissFEL. Eventually, the dimension of elemental absorption sides at a synchrotron beamline making use of JUNGFRAU is also shown. open access.In this work, the spectroscopic shows of the latest cadmium-zinc-telluride (CZT) pixel detectors recently developed at IMEM-CNR of Parma (Italy) tend to be provided. Sub-millimetre arrays with pixel pitch less than 500 µm, centered on boron oxide encapsulated vertical Bridgman grown CZT crystals, had been fabricated. Exemplary room-temperature performance characterizes the detectors even at high-bias-voltage procedure (9000 V cm-1), with power resolutions (FWHM) of 4% (0.9 keV), 1.7% (1 keV) and 1.3per cent (1.6 keV) at 22.1, 59.5 and 122.1 keV, respectively. Charge-sharing investigations had been carried out with both uncollimated and collimated synchrotron X-ray beams with particular awareness of the minimization associated with the cost losings at the inter-pixel space area. High-rate measurements shown the absence of high-flux radiation-induced polarization phenomena as much as 2 × 106 photons mm-2 s-1. These activities are in the framework of a worldwide collaboration from the development of energy-resolved photon-counting systems for high-flux energy-resolved X-ray imaging.A framework based on physical optics for simulating the end result of imperfect element refractive lenses (CRLs) upon an X-ray beam is described, taking into consideration assessed phase errors acquired from at-wavelength metrology. A CRL bunch is modelled, with increasing complexity, as just one thin stage element, then as a far more realistic ingredient element including absorption and width effects, and finally adding realistic optical flaws into the CRL. Coherent and partially coherent simulations utilizing Synchrotron Radiation Workshop (SRW) are accustomed to evaluate the different models, the results of the phase errors and also to look at the credibility of the design equations and suitability of the figures of merit.A parallel paper [Berujon, Cojocaru, Piault, Celestre, Roth, Barrett & Ziegler (2020), J. Synchrotron Rad. 27, 284-292] assessed theoretically some of the available handling schemes for X-ray wavefront sensing based on random modulation. Shown listed here are experimental applications associated with the way of characterizing both refractive and reflective optical elements. These quick and accurate X-ray at-wavelength metrology methods can help the make of X-ray optics that transport X-ray beams with at least quantity of wavefront distortion. It is also recalled just how such practices can facilitate web optimization of active optics.X-ray near-field speckle-based phase-sensing approaches provide efficient method of characterizing optical elements. Provided listed here is a theoretical writeup on several of these speckle practices within the framework of optical characterization, and a generalization associated with the idea is provided. As is additionally demonstrated experimentally in a parallel report [Berujon, Cojocaru, Piault, Celestre, Roth, Barrett & Ziegler (2020), J. Synchrotron Rad. 27, (this problem)], the strategy theoretically created here can be employed to different beams and optics and within many different situations where at-wavelength metrology is desired. By comprehending the differences when considering the various handling practices, you can easily find and implement the most suitable method for every metrology scenario.MAX IV is a fourth-generation, or diffraction-limited, synchrotron light source with a number of state-of-the-art beamlines. The overall performance of a beamline is, to a higher level, set because of the power quality it can attain, which often is influenced to a large degree because of the monochromator. Throughout the design phase of a monochromator, the technical needs should be totally understood and satisfied with margin. During commissioning, the performance lysylhydroxylase signal should be verified and optimized. In this paper, six smooth X-ray monochromators at MAX IV beamlines (Bloch, Veritas, HIPPIE, SPECIES, FinEstBeAMS and SoftiMAX) are analyzed with a focus on their resolving power, power range and the time required to change measurement range, as those variables are dependent on each other. The monochromators have a modern commercial design, planned and created in close collaboration aided by the suppliers. This paper aims to provide the current condition of this commissioning at maximum IV with increased exposure of elucidating the mechanical restrictions regarding the performance for the monochromators. It contains evaluation of the outcome and our approach to achieve quick and high-resolution monochromators. available access.With the development of the multi-bend achromats in the new fourth-generation storage rings the emittance has actually decreased by an order of magnitude resulting in increased brightness. However, the greater brightness comes with smaller ray sizes and narrower radiation cones. For that reason, the requirements on technical stability about the beamline components increases. Here an innovative five-axis parallel kinematic mirror product for use with soft X-ray beamlines utilizing off-axis grazing-incidence optics is provided.
