Physics Colloquium: What is happening inside the synchrotron?
Hovedinnhold
During the last couple of decades the development of large scale facilities for the generation of X-rays (so-called synchrotron radiation) has almost revolutionized research areas where structural studies of condensed matter (primarily solid states, but also fluids and solutions) are important. In the talk we will first have a look at what synchrotron radiation is and how it is generated. In particular, we will review some recent developments concerning focusing of X-rays - with the aim of developing an X-ray transmission microscope. Finally, some recent diffraction experiments, yielding interesting new information about a seemingly well-known compound, will be presented.
Helge Bøvik Larsen is professor of materials physics at the University of Stavanger. He received his PhD from NTNU in 1997. His research is primarily on diffraction physics and X-ray wave propagation in crystals, but also on solid state structural phase transformations. He has actively been using synchrotron radiation facilities for the last 20 years, and is currently the national delegate to the European Synchrotron Users Organization (ESUO).
