This book was released on 2013-11-09 with total page 382 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is based on presentations to the International Conference of X-Ray Micro scopy and Spectromicroscopy, XRM 96, which took place in Wiirzburg, August 19- 23, 1996. The conference also celebrated the lOOth anniversary of the discovery of X rays by Wilhelm Conrad Rontgen on November 8, 1895, in Wiirzburg. This book contains state-of-the-art reviews and up-to-date progress reports in the field of X-ray microscopy and spectromicroscopy, including related new X-ray optics and X-ray sources. It reflects the lively activities within a relatively new field of science which combines the development of new instruments and methods with their applications to numerous topical scientific questions. The applications range from biological and medical topics, colloid physics, and soil sciences to solid-state physics, material sciences, and surface sciences. Their variety demonstrates the interdisci plinary and cooperative character of this field and the growing demand for micro scopic and spectromicroscopic information on the nanometer scale and under specific sample conditions, for example in wet (natural) surroundings or on a solid surface.

Download or read book A Study on New Approaches in Coherent X ray Microscopy of Biological Specimens written by Klaus Giewekemeyer and published by Universitätsverlag Göttingen. This book was released on 2011 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of coherent x rays for microscopic imaging has seen a rapid and ongoing development within the past decade, driven by an increasing availability of highly brilliant and coherent sources worldwide. Accordingly, novel methods have been developed, which replace the microscope‘s objective lens by a numerical reconstruction scheme. The aim of the present work is to study how very recent experimental and algorithmic developments in the field can be implemented towards a highly sensitive and fully quantitative microscopy method for imaging of biological cells. To this end, different experimental approaches are studied, based on coherent far-field as well as near-field diffraction. At first, an application of the novel ptychographic imaging method to single biological cells is presented. In particular, it is demonstrated how weakly scattering biological specimens can be imaged with fully quantitative density contrast. Alongside, a sueccessful extension of the method towards soft x-ray energies is described.In the second part of the work it is shown how x-ray waveguides can be used as a point source for propagation-based microscopy of single cells in the hard x-ray regime. The specifically devised iterative reconstruction scheme allows for full quantitativity and high sensitivity and thus enables an application to single biological cells. The work contains a thorough introduction into the x-ray optical methods applied and aims at a useful and self-contained overview on aspects of signal and Fourier theory relevant for the used numerical propagation schemes.

Download or read book Soft X ray Optics written by Eberhard Spiller and published by SPIE Press. This book was released on 1994 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text describes optics mainly in the 10 to 500 angstrom wavelength region. These wavelengths are 50 to 100 times shorter than those for visible light and 50 to 100 times longer than the wavelengths of medical x rays or x-ray diffraction from natural crystals. There have been substantial advances during the last 20 years, which one can see as an extension of optical technology to shorter wavelengths or as an extension of x-ray diffraction to longer wavelengths. Artificial diffracting structures like zone plates and multilayer mirrors are replacing the natural crystals of x-ray diffraction. Some of these structures can now be fabricated to have diffraction-limited resolution. The new possibilities are described in a simple, tutorial way.

Download or read book X Ray Microscopy III written by Alan G. Michette and published by Springer. This book was released on 2013-06-05 with total page 499 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth of interest and research activity in X -ray microscopy is reflected in the increasing size and scope of a related series of international conferences, the latest of which (XRM90) was held at King's College London (3-7 September 1990) with over 130 delegates. Previous conferences in Gottingen and Brookhaven resulted in books in the Springer Series in Optical Sciences, and this volume, the proceedings of XRM90, maintains this tradition. Because of the large number of papers their lengths were strictly limited and, while most papers can be directly identified with conference presentations, in a few cases those on similar topics by the same authors have been combined into a longer paper to allow better use of the space. The book is divided into six parts, with Parts IT-VI covering the major areas of interest at the conference. In Part 1 are two overviews; Ron Burge presented the opening paper of the conference, while the closing, summary, contrlbution by Janos Kirz is included here as a comprehensive introduction to the remainder of the book. Part IT covers developments in X -ray sources and optics. The high average brightnesses of synchrotron radiation sources have made many applications pos sible, while the more convenient, laboratory-based, plasma sources offer much promise for the future. Several contributions report significant advances in X-ray optics, which must clearly continue fully to exploit the latest sources.

Download or read book Further Development of Soft X ray Scanning Microscopy with Anelliptical Undulator at the Advanced Light Source written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Soft x-ray scanning microscopy (1) is under continuing development at the Advanced Light Source. Significant progress has been made implementing new scan control systems in both operational microscopes (2) and they now operate at beam lines 5.3.2 and 11.0.2 with interferometer servo scanning and stabilization. The interferometer servo loop registers the images on a universal x/y coordinate system and locks the x-ray spot on selected features for spectro-microscopic studies. At the present time zone plates are in use with 35nm outer zone width and the imaging spatial resolution is at the diffraction limit of these lenses. Current research programs are underway in areas of polymer chemistry, environmental chemistry and materials science. A dedicated polymer STXM is in operation on a bend magnet beam line (4) and is the subject of a separate article (3) in this issue. Here we focus on the capabilities of STXM at a new beam line that employs an elliptical undulator (5) to give control of the polarization of the x-ray beam. This facility is in the process of commissioning and some results are available, other capabilities will be developed during the first half of 2003.

Download or read book X Ray Microscopy written by G. Schmahl and published by Springer. This book was released on 2013-10-03 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: X-ray microscopy fills a gap between optical and electron microscopy. Using soft x-rays, a resolution higher than with visible light can be obtained. In comparison to electron microscopy, thick, wet, unstained specimens can be examined. This is especially advantageous for biological applications. The intense synchrotron radiation of electron storage rings and the de­ velopment of optical elements for soft x-rays render x-ray microscopy feasi­ ble for basic research. Wider applications will be possible in the future with the development of laboratory x-ray sources and microscopes. In 1979 a conference on x-ray microscopy was organized by the New York Academy of Sciences and in 1981 a symposium on high resolution soft x-ray optics was held at Brookhaven. The present volume contains the contributions to the sympos i um "X-Ray Microscopy", organ i zed by the Akademie der Wi ssen­ schaften in Gottingen in September 1983. In their capacity as conference chairmen, the editors would like to thank the Akademie der Wissenschaften, especially Prof. H.G. Wagner, Secretary of the Academy, and Mr. J. Pfahlert for organizing the symposium. We are in­ debted to the Stiftung Volkswagenwerk for financial support. The symposium was held at the Max-Planck-Institut fUr Stromungsforschung. We are grateful for their hospitality and assistance during the symposium. Thanks are due to all authors and to the Springer Verlag for their combined efforts. We thank Dipl.-Phys. P. Guttmann, Dr. B. Niemann and Mrs. A. Marienhagen for their assistance during the final preparation of the manuscripts.

Download or read book Soft X ray Spectromicroscopy Development for Materials Science at the Advanced Light Source written by and published by . This book was released on 1996 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several third generation synchrotron radiation facilities are now operational and the high brightness of these photon sources offers new opportunities for x-ray microscopy. Well developed synchrotron radiation spectroscopy techniques are being applied in new instruments capable of imaging the surface of a material with a spatial resolution smaller than one micron. There are two aspects to this. One is to further the field of surface science by exploring the effects of spatial variations across a surface on a scale not previously accessible to x-ray measurements. The other is to open up new analytical techniques in materials science using x-rays, on a spatial scale comparable to that of the processes or devices to be studied. The development of the spectromicroscopy program at the Advanced Light Source will employ a variety of instruments, some are already operational. Their development and use will be discussed, and recent results will be presented to illustrate their capabilities.

Download or read book Soft X ray Microscopy a Powerful Analytical Tool to Image Magnetism Down to Fundamental Length and Times Scales written by and published by . This book was released on 2008 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The magnetic properties of low dimensional solid state matter is of the utmost interest both scientifically as well as technologically. In addition to the charge of the electron which is the base for current electronics, by taking into account the spin degree of freedom in future spintronics applications open a new avenue. Progress towards a better physical understanding of the mechanism and principles involved as well as potential applications of nanomagnetic devices can only be achieved with advanced analytical tools. Soft X-ray microscopy providing a spatial resolution towards 10nm, a time resolution currently in the sub-ns regime and inherent elemental sensitivity is a very promising technique for that. This article reviews the recent achievements of magnetic soft X-ray microscopy by selected examples of spin torque phenomena, stochastical behavior on the nanoscale and spin dynamics in magnetic nanopatterns. The future potential with regard to addressing fundamental magnetic length and time scales, e.g. imaging fsec spin dynamics at upcoming X-ray sources is pointed out.
