X-Ray Optics Research

I am working on a project with Prof. David Allred and a group of undergraduate and graduate students that began with designing and testing a mirror for the Medium Exploror (MIDEX) Program. Our mirror was part of a device for imaging the upper atmosphere from space at a wavelength of 304 Angstroms. The mirror we designed was to have a relatively high reflectivity at 304 Angstroms (>20%) and a low reflectivity at 584 Angstroms (<0.2%). The research involves computer aided optical design, multi-layer mirror fabrication, measurement of optical properties of materials, and design and fabrication of test and measurement components. The mirror was incorporated in the instrument being built by the Optical Sciences Center at the University of Arizona. After testing, the instrument was integrated with others in the payload and launched in early 2000. My students and I are responsible for optical design and other computational aspects of the program. In addition we built a reflectometer for measuring optical properties of XUV optics and coatings. Recently, we designed and built an XUV polarimeter to enable us to accurately determine optical constants in this wavelength regime.

Our group uses the Advanced Light Source at Lawrence Berkeley Lab for some of our research.
