Presentation Transcript

  1. Introduction to Synchrotron Radiation http://serc.carleton.edu/NAGTWorkshops/mineralogy/mineral_physics/synchrotron_facilities.html

  2. Synchrotron radiation • Produces high energy particles (protons, neutrons, electrons) • Particles produced in electron gun by a heated tungsten oxide cathode • Magnets and radio frequency accelerate particles in a circular path • Producesspectrum with broad wavelengths and strengths http://www.aps.anl.gov/About/Welcome/

  3. Where do the particles go? Electron gun Booster ring Storage ring Beamline Optics cabin Instrument www.diamond.ac.uk

  4. Breadth of techniques Spectroscopy Scattering Hard x-ray spectroscopy Metrology Optics Detector Calibrations Soft x-ray spectroscopy Hard x-ray diffraction Hard x-ray scattering Macromolecular crystallography Soft x-ray scattering Imaging Hard x-ray imaging Lithography Soft x-ray scattering https://beam.aps.anl.gov/pls/apsweb/beamline_display_pkg.technique_dir

  5. Is it worth it? Disadvantages • Have proposal accepted • Travel to beamline • Beamline instability Advantages • Continuous spectrum • High flux • High brightness • High coherence • Better signal to noise ratio • Able to detect nanoscale materials

  6. Where are synchrotrons in USA?
