  1. Building and Testing an XUV Polarimeter Raymond Rios XUV Research Group 16 March 2002 Brigham Young University

  2. Extreme Ultraviolet Light • What is it? • Why do we study it? • BYU research in XUV Wavelength = 19.5 nm

  3. Purpose of Optical Constants • Analyze information from mirrors • Taylor multilayer mirrors • Literature lacks reliable constants

  4. Polarimeter Polarimeter vs Ellipsometry

  5. Physical Requirements for the Polarimeter • Must be in a vacuum • Reliable Monochromatic XUV Source • Aperature

  6. Technical Concerns • Align the system • Find the point of steady light reflection • Creating program that analyzes data

  7. Taking mesurements • Measure at specific wavelength • Fit the derived equations to our results by varying the n

  8. Present Challenges • Lack of a reliable source • Buggy Program, Negative sign problem

  9. Future Goals • Work with multilayer mirrors • Analyzing the optical constants of Uranium Oxide among other compounds for mirrors
