Extreme ultraviolet light
Extreme Ultraviolet Light

  • What is it?

  • Why do we study it?

  • BYU research in XUV

Wavelength = 19.5 nm


Purpose of optical constants
Purpose of Optical Constants

  • Analyze information from mirrors

  • Taylor multilayer mirrors

  • Literature lacks reliable constants


Polarimeter
Polarimeter

Polarimeter vs Ellipsometry


Physical requirements for the polarimeter
Physical Requirements for the Polarimeter

  • Must be in a vacuum

  • Reliable Monochromatic XUV Source

  • Aperature


Technical concerns
Technical Concerns

  • Align the system

  • Find the point of steady light reflection

  • Creating program that analyzes data


Taking mesurements
Taking mesurements

  • Measure at specific wavelength

  • Fit the derived equations to our results by varying the n


Present challenges
Present Challenges

  • Lack of a reliable source

  • Buggy Program, Negative sign problem


Future goals
Future Goals

  • Work with multilayer mirrors

  • Analyzing the optical constants of Uranium Oxide among other compounds for mirrors
