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

2 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 3 Past Projects and Applications ESA Mars Express Probe, Venus Express Probe Astronomy Microscopy Plasma Diagnostics

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

5 5 What is a Grazing Incidence Monochromator Anyway?

6 6 Set-Up -- Insert GIMS here

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

8 8 Reflection and Absorption 30 Å Pt

9 9 Why We Care

10 10 Benefits Less Absorption Higher Wavelengths 2 Sources And…

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