Abstract

In this work, we performed fully- and partially-coherent synchrotron emission and propagation simulations with the "Synchrotron Radiation Workshop" computer code to analyze the performance of two soft X-ray beamlines under development at the National Synchrotron Light Source II: Soft X-ray Nanoprobe (SXN), and Angle-Resolved Photoemission Spectroscopy (ARPES) and Resonant Inelastic X-ray Scattering (RIXS) Imaging (ARI). The SXN beamline intends to provide high flux and high spatial resolution coherent soft X-ray imaging capabilities using both zone plate and lensless coherent imaging techniques. The ARI beamline aims to perform high flux ARPES and RIXS experiments with a focal spot size at the sample approaching 100 nm using highly-demagnifying mirrors in Kirkpatrick-Baez geometry. To accurately calculate the resolution and the degree of X-ray coherence provided by the two state-of-the-art beamlines, partial coherence effects are required to be taken into account in wave optics simulations for these two beamlines. In this talk, beamline performance parameters such as spot size, degree of coherence, flux, and energy resolution at the sample are presented. The effects of mirror surface slope errors on beamline performance were studied and some suggestions for further optimization are discussed.

Simulation and optimization of the NSLS-II SRX beamline combining ray-tracing and wavefront propagation

Journal Article De, Andrade V ; Thieme, J ; Chubar, O - Advances in Computational Methods for X-Ray Optics II

The Sub-micron Resolution X-ray spectroscopy (SRX) beamline will benefit from the ultralow emittance of the National Synchrotron Light Source II to address a wide variety of scientific applications studying heterogeneous systems at the sub-micrometer scale. This work focuses on the KB branch ({Delta}E: 4.65-28 keV). Its main optical components include a horizontally focusing mirror forming an adjustable secondary source, a horizontally deflecting monochromator and two sets of Kirkpatrick-Baez mirrors as focusing optics of two distinct inline stations for operations requiring either high flux or high resolution. In the first approach, the beamline layout was optimized with ray-tracing calculations involving Shadowvuimore »« less

HYBRID simulations of diffraction-limited focusing with Kirkpatrick-Baez mirrors for a next-generation In Situ hard X-ray nanoprobe

Journal Article Maser, Jorg ; Shi, Xianbo ; Reininger, Ruben ; ... - Metallurgical and Materials Transactions. A, Physical Metallurgy and Materials Science

Next-generation hard X-ray nanoprobe beamlines such as the In Situ Nanoprobe (ISN) beamline being planned at the Advanced Photon Source aim at providing very high spatial resolution while also enabling very high focused flux, to study complex materials and devices using fast, multidimensional imaging across many length scales. The ISN will use diffractive optics to focus X-rays with a bandpass of ΔE/E = 10^–4 into a focal spot of 20 nm or below. Reflective optics in Kirkpatrick-Baez geometry will be used to focus X-rays with a bandpass as large as ΔE/E = 10^–2 into a focal spot of 50 nm.more »« less

TGM-to-SGM conversion at NSLS beamline U7A: Recyclying of beamline components

Journal Article Hulbert, S L ; Dong, Q - Review of Scientific Instruments

The U7A bending magnet toroidal grating monochromator (TGM) beamline has been converted into a spherical grating monochromator (SGM) type, without constructing any new vacuum components. That is, the mirror, slit, and grating chambers have been recycled. The inherited optical arrangement and the recycling concept prevented the use of {open_quote}{open_quote}standard{close_quote}{close_quote} SGM Kirkpatrick-Baez collecting and focusing mirrors at the front end. We show that this modification is not a serious detriment to the optical properties of the resulting beamline. Specifically, the resolution is completely unaffected and the throughput is approximately 2/3 of the {open_quote}{open_quote}standard{close_quote}{close_quote} SGM value.

A Next-Generation Hard X-Ray Nanoprobe Beamline for In Situ Studies of Energy Materials and Devices

Journal Article Maser, Jong ; Lai, Barry ; Buonassisi, Toni ; ... - Metallurgical and Materials Transactions. B, Process Metallurgy and Materials Processing Science

The Advanced Photon Source is developing a suite of new X-ray beamlines to study materials and devices across many length scales and under real conditions. One of the flagship beamlines of the APS upgrade is the In Situ Nanoprobe (ISN) beamline, which will provide in situ and operando characterization of advanced energy materials and devices under varying temperatures, gas ambients, and applied fields, at previously unavailable spatial resolution and throughput. Examples of materials systems include inorganic and organic photovoltaic systems, advanced battery systems, fuel cell components, nanoelectronic devices, advanced building materials and other scientifically and technologically relevant systems.

An X-ray Focusing System Combining a Sagittally-bent Crystal and a Kirkpatrick-Baez System

Journal Article Ziegler, E ; Bigault, T ; Hoszowska, J - AIP Conference Proceedings

In the production of x-ray microbeams a trade-off between flux and beam size must often be made, particularly when using a bending magnet synchrotron source since the radiation emitted in the horizontal direction is not collimated. To circumvent this problem we have combined the diffraction from a sagitally-bent crystal with the meridional focusing of a Kirkpatrick-Baez (KB) system composed of two reflective surfaces coated with a platinum layer (1st mirror, vertical deflection) and with a Ni/B4C multilayer (2nd mirror, horizontal deflection). The experiments were performed at the ESRF BM5 beamline, for which the most favorable arrangement consisted of illuminating amore »« less
