X-ray spectromicroscopy with the scanning transmission X-ray microscope at BESSY II.
Using the scanning transmission X-ray microscope at BESSY II, colloidal structures from a Chernozem soil have been studied with a spatial resolution around 60 nm and a spectral resolution of 1,700 at the K-absorption edge of carbon. Elemental mapping has been used to determine the distribution of organic matter within the colloidal structures. Spectra have been extracted from image stacks to ob...
متن کاملQuantitative phase imaging with a scanning transmission x-ray microscope.
We obtain quantitative phase reconstructions from differential phase contrast images obtained with a scanning transmission x-ray microscope and 2.5 keV x rays. The theoretical basis of the technique is presented along with measurements and their interpretation.
متن کاملA scanning transmission x-ray microscope for materials science spectromicroscopy at the advanced light source
Design and performance of a scanning transmission x-ray microscope ~STXM! at the Advanced Light Source is described. This instrument makes use of a high brightness undulator beamline and extends the STXM technique to new areas of research. After 2.5 years of development it is now an operational tool for research in polymer science, environmental chemistry, and magnetic materials. © 1998 America...
متن کاملExperimental investigation of beam heating in a soft X-ray scanning transmission X-ray microscope.
A variable temperature sample holder with an operational range of 15 to 200 °C and an accuracy of ±1 °C has been fabricated for scanning transmission X-ray microscopes (STXM). Here we describe the device, and use it to image the polycrystalline morphology of solid stearic acid and palmitic acid at temperatures near their respective melting points as a means of checking for possible sample heati...
متن کاملChemically Sensitive Tomography at 50 nm Spatial Resolution using a Soft X- ray Scanning Transmission X-Ray Microscope
Previous very successful soft X-ray microscopy tomography experiments [1-3] have been performed at a single photon energy. They have provided high spatial resolution, density based 3D images, but with only limited chemical information. We are developing computed angle-scan tomography in a scanning transmission x-ray microscope (STXM) for chemical visualization of a 3D spatial volume. Our goal i...
