Elements Of Modern X-ray Physics

Professor Emeritus Jens Als-Nielsen of the Niels Bohr Institute, University of Copenhagen, has been a pioneer in the field of neutron and x-ray scattering contributing to setting high standards for large international synchrotron centres. Today Jens Als-Nielsen's research is still - even after his official retirement - concentrated around x-ray radiation's potential in biological and medical research.? He was educated as a civil engineer in the field of electrophysics and from 1961-1995 was employed at the Riso National Laboratory, as section leader for the Solid-State Physics Section and later as division leader for the Physics Division. He has spent time at the European Synchrotron Radiation Facility, ESRF, Grenoble. From 1995 until his retirement in 2007 he was professor in experimental solid-state physics at the Niels Bohr Institute, University of Copenhagen. In 1985 he received the European Physical Society's Hewlett-Packard prize in solid-state physics and in 2009 the Velux Fonden's Honour Award for his research in the field of neutron and X-ray scattering. Professor Desmond McMorrow is Professor of Physics at University College London. He received his B.Sc from Sheffield University in 1983and his PhD in 1987 from the University of Manchester. After spending time in research at Edinburgh and Oxford he then worked with at the Riso National Laboratory and collaborated with Professor Als-Nieslen between 1998 and 2003. In 2004 he took up his position at UCL and received from 2004 - 2009 the Royal Society Wolfson Merit Award. His research is focussed on understanding how electrons organise themselves in solids to produce the wonderfully diverse range of phenomena encountered in modern condensed matter physics. His research is based mainly on using x-rays and neutrons to probe the structural and magnetic correlations that dominate the low-energy behaviour of these and other interesting classes of solids.

Elements of Modern X-ray Physics


Eagerly awaited, this second edition of a best-selling text comprehensively describes from a modern perspective the basics of x-ray physics as well as the completely new opportunities offered by synchrotron radiation. Written by internationally acclaimed authors, the style of the book is to develop the basic physical principles without obscuring them with excessive mathematics.

One of the last regions of the electromagnetic spectrum to be developed is that extending from the extreme ultraviolet to hard x-rays, generally shown as a dark region in charts of the spectrum. It is a region where there are a large number of atomic resonances, leading to absorption of radiation in very short distances, typically measured in nanometers (nm) or micrometers (microns, µm), in all materials. This has historically inhibited the pursuit and exploration of the region. On the other hand, these same resonances provide mechanisms for both elemental (C, N, O, etc.) and chemical (Si, SiO2, TiSi2) identification, creating opportunities for advances in both science and technology. Furthermore, because the wavelengths are relatively short, it becomes possible to study nanoscale structures using the techniques of absorption, scattering and microscopy. To exploit these opportunities requires advances in relevant technologies, for instance in nanofabrication. These in turn lead to new scientific understandings, in subjects such as materials science, surface science, chemistry, biology and physics, providing feedback to the enabling technologies. Development of the extreme ultraviolet, soft and hard x-ray spectral regions is presently in a period of rapid growth and interchange among science and technology. 041b061a72
