X-ray Interferometry Development at the Advanced Photon Source*
In this paper, we report initial test results of a four-bounce Bragg reflection Xray interferometer at 7.46 keV and, for the first time to our knowledge, at the higher energy of 14.91 keV where the spectral acceptance is much smaller. INTRODUCTION The triple Laue (LLL) interferometer is one of the most used X-ray interferometers, be it in ultra-precision metrology’ or in imaging techniques. The...
متن کاملNew developments in micro-X-ray diffraction and X-ray absorption spectroscopy for high-pressure research at 16-BM-D at the Advanced Photon Source.
The monochromator and focusing mirrors of the 16-BM-D beamline, which is dedicated to high-pressure research with micro-X-ray diffraction (micro-XRD) and X-ray absorption near edge structure (XANES) (6-45 keV) spectroscopy, have been recently upgraded. Monochromatic X-rays are selected by a Si (111) double-crystal monochromator operated in an artificial channel-cut mode and focused to 5 μm × 5 ...
متن کاملOptical design of the Short Pulse Soft X-ray Spectroscopy beamline at the Advanced Photon Source
The Short Pulse X-ray facility planned for the Advanced Photon Source (APS) upgrade will provide two sectors with photon beams having picosecond pulse duration. The Short Pulse Soft X-ray Spectroscopy (SPSXS) beamline will cover the 150-2000 eV energy range using an APS bending magnet. SPSXS is designed to take full advantage of this new timing capability in addition to providing circular polar...
متن کاملStatus of the Short-pulse X-ray Project at the Advanced Photon Source*
The Advanced Photon Source Upgrade (APS-U) Project at Argonne will include generation of short-pulse x-rays based on Zholents’ deflecting cavity scheme [1]. We have chosen superconducting (SC) cavities in order to have a continuous train of crabbed bunches and flexibility of operating modes. In collaboration with Jefferson Laboratory, we are prototyping and testing a number of single-cell defle...
متن کاملMm-wave Cavity/klystron Developments Using Deep X-ray Lithography at the Advanced Photon Source
Recent microfabrication technologies based on LIGA (German acronym for Li thographe, Galvanoformung, und Abformung) have been applied to build high-aspect-ratio, metallic or dielectric, planar structures suitable for highfrequency rf cavity structures. The cavity structures would be used as parts of linear accelerators, microwave undulators, and mm-wave amplifiers. The microfabrication process ...
