Presentation Transcript

  1. Advantages of a Grazing Incidence Monochromator in the Extreme Ultraviolet By Sarah Barton

  2. Thin Films We “grow” films with thicknesses in the range of 200-400 Å We measure reflectance properties of different films in the extreme ultraviolet Methods used for creating films include sputtering and evaporation

  3. ESA Mars Express Probe, Venus Express Probe Astronomy Microscopy Plasma Diagnostics Past Projects and Applications

  4. The Advanced Light Source at Lawrence Berkeley National Laboratories • Synchrotron • High Intensity • Shorter Wavelengths • Continuous Spectrum • Many Different Gratings - Including Grazing Incidence

  5. What is a Grazing Incidence Monochromator Anyway?

  6. Set-Up -- Insert GIMS here

  7. Differences • Near-Grazing vs. Near-Normal Angles • More Reflective for Higher Wavelengths • Possible Higher Intensity • Smaller Size

  8. Reflection and Absorption • 30 Å • Pt

  9. Why We Care

  10. Benefits • Less Absorption • Higher Wavelengths • 2 Sources • And…

  11. Convenience! The Under Ground Lab is a lot closer than California!
