Fourier Transform soft X-ray (FTXR) Spectral Imager for Fingerprinting Bonding Structure in Minerals

<B>Abstract:</B>

The promise of adapting Fourier Transform (FT) techniques used in the IR into the soft X-ray region has been advocated in the past as a possible route to constructing a miniature spectral imager with spatial and spectral resolution similar to that attainable with a grating system using synchrotron radiation. With a dramatically increased resolution over IR, core-level shift spectra of chemically and biologically significant elements could be mapped for each pixel of the image. We have initiated development of FTXR imager based on the use of a Mach-Zender type interferometer. This talk will describe the principle of operation of the instrument, with emphasis on development of beam-splitting mirrors - the enabling technology for the interferometer - in our laboratory at MDL, JPL.

Light refreshments will be served after the seminar
