European Synchrotron Radiation Facility Highlights 2008 (ESRF) Summary:Sine Larsen, Director of Research * Publisher: The European Synchrotron Radiation Facility (ESRF) * Number Of Pages: 145 * Publication Date: February 2009 * Binding: pdfSCIENTIFIC DOCUMENTATION Highlights - selected results of the most impressive experiments carried out at ESRF during a year (published each year).About the Publisher: The European Synchrotron Radiation Facility (ESRF), located in Grenoble - France, is a joint facility supported and shared by 19 European countries. The ESRF operates the most powerful synchrotron radiation source in Europe. Each year several thousand researchers travel to Grenoble where they work in a first-class scientific environment to conduct exciting experiments at the cutting edge of modern science. At the ESRF, physicists work side by side with chemists and materials scientists. Biologists, medical doctors, meteorologists, geophysicists and archaeologists have become regular users. Industrial applications are also growing, notably in the fields of pharmaceuticals, cosmetics, petrochemicals and microelectronics.
