  2. X-rays were discovered in 1895 by the German physicist Wilhelm Röntgen (also spelled Roentgen). He received the first Nobel Prize in physics in 1901 in recognition of the extraordinary services he has rendered by the discovery of the remarkable rays subsequently named after him
  3. Key points. X-rays are produced by interaction of accelerated electrons with tungsten nuclei within the tube anode. Two types of radiation are generated: characteristic radiation and bremsstrahlung (braking) radiation. Changing the X-ray machine current or voltage settings alters the properties of the X-ray beam

The name \x ray is generally given to a photon if it is emitted by a free or bound electron and has an en-ergy in the range from about 0.1 keV to about 100 keV. Photons emitted directly by nuclei are generally called gamma rays even if their energy is in the conventional TABLE I. Correspondence between x ray diagram levels and electron con gurations A basic knowledge of X-ray physics is complementary to knowledge of X-ray interpretation

Basic physics of X-ray imaging 1. INTRODUCTION In X-ray diagnostics, radiation that is partly transmitted through and partly absorbed in the irradiated object is utilised. An X-ray image shows the variations in transmission caused by structures in the object of varying thickness, density or atomic composition. I Discovery of x-rays Discovered in 1895 by German physicist named Wilhelm Roentgen. He found shadow of his bone on fluorescent screen. 5. X-rays are a form of electromagnetic radiation similar to visible light but with short wave length. 6. Radiation physics. 7

X-ray imaging utilises the ability of high frequency electromagnetic waves to pass through soft parts of the human body largely unimpeded.

In the early 1970s, the X-ray laser seemed to be out of reach as most lasers of the time peaked at 110 nanometers, well short of the largest X-rays of 10 nanometers. This was because of the amount of energy required to get the material stimulated was so high that it needed to be delivered in a quick firing pulse that further complicated the reflective ability needed to have a powerful laser To illustrate this effect, Röntgen took an X-ray photograph of his wife's hand, which produced an almost ghoulish image that clearly showed her bones and wedding ring. One of the recipients of these letters was Franz Exner, a former fellow student of Röntgen and at the time professor of experimental physics in Vienna Lectures are given on the basics of X-ray physics, exercises in the lab will provide hands-on experience, and the course concludes with a stay at the synchrotron facility MAXlab in Lund, where students will carry out a number of basic experiments with X-ray synchrotron radiation.

X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. The passage of X-rays through materials, including biological tissue, can be recorded. Thus, analysis of X-ray images of the body is a valuable medical diagnostic tool X-ray protein crystallography is a technique by which it is possible to determine the three dimensional positions of each atom in a protein. Now over 100 years old, x-ray crystallography was first used to determine the three dimensional structures of inorganic materials, then small organic molecules, and finally macromolecules like DNA and proteins

Understanding the molecular radiation damage is crucial in radiobiology, molecular physics, and atmospheric science. In this thesis, the initial steps of radiation damage of anhydrous gas-phase molecules and hydrated nanoparticles were studied using synchrotron radiation based electron-ion coincidence spectroscopy and X-ray absorption spectroscopy under vacuum conditions X-ray production typically involves bombarding a metal target in an x-ray tube with high speed electrons which have been accelerated by tens to hundreds of kilovolts of potential. The bombarding electrons can eject electrons from the inner shells of the atoms of the metal target

In x-ray absorption spectroscopy (XAS) the energy of the absorbed photon raises an electron from a deeply bound state into unoccupied bound states or it gains enough energy to escape the atom. The absorption spectrum thus contains detailed information about the density of empty states and allows conclusions about coordination, oxidation state and many more information about the local structure X-ray and Neutron Science is a section with about 40 researchers, working closely to other sections at the Niels Bohr Institute, other institutes at the University of Copenhagen, X-ray and neutron facilities around the world, and a number of other international partners
