High-resolution X-ray emission and X-ray absorption spectroscopy.
In this review, high-resolution X-ray emission and X-ray absorption spectroscopy will be discussed. The focus is on the 3d transition-metal systems. To understand high-resolution X-ray emission and resonant X-ray emission, it is first necessary to spend some time discussing the X-ray absorption process. Section II discusses 1s X-ray absorption, i.e., the K edges, and section III deals with 2p X...
متن کاملWavelength Dispersive Optics for Ultrafast X-ray Spectroscopy at LCLS
Ultrafast X-ray absorption spectroscopy (XAS) performed at an x-ray free electron laser (XFEL) is a potentially very powerful tool to study numerous phenomena including dissociation in the gas phase , phase transitions in material science 2 and metal ligand charge transfer reactions 3 in coordination chemistry (for a recent review see ). At energies of 5-8 keV the LCLS is expected to provide pu...
متن کاملA high resolution, hard x-ray bio-imaging facility at SSRL.
The old saying that seeing is believing has particular resonance for studying biological cells and tissues. Since 1677, when Anton van Leeuwenhoek used a simple light microscope to discover single cell organisms, scientists have relied on structural information obtained from microscopes with improving capabilities to advance the understanding of how biological systems work. Optical and electron...
متن کاملThe LCLS X-ray FEL at SLAC
The design status and R&D plan of a 1.5 Å SASE-FEL at SLAC, called the Linac Coherent Light Source (LCLS), are described. The LCLS utilizes one third of the SLAC linac for the acceleration of electrons to about 15 GeV. The FEL radiation is produced in a long undulator and is directed to an experimental area for its utilization. The LCLS is designed to produce 300 fsec long radiation pulses at t...
متن کاملHigh-resolution X-ray fluorescence and excitation spectroscopy of metalloproteins.
A spectrograph has been developed with sufficient efficiency to make high-resolution fluorescence experiments on metalloproteins possible. The resolution of this spectrometer can reach 0.45 eV at 7.1 keV emission energy. The focus images of this multiple curved-crystal array spectrometer are presented. The chemical sensitivity of Kbeta emission spectra can be used to identify chemical states, a...
