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. Click here for some pictures
and a description some of our trips there.
