Paper Abstract

High spectral resolution x-ray transmission measurements in the energy range 60 - 1950 eV have been conducted at BESSY 1 synchrotron (Berlin) on samples of aluminum coated Lexan in order to define an accurate model of x-ray absorption near edge structures for the AXAF-HRC UV/ion shields material. A large number of energies have been surveyed with a spectral resolution ranging from E/(Delta) E equals 2500 at 100 eV to E/(Delta) E equals 700 at Al-K edge. The spatial variations of such absorption structures also have been investigated surveying different positions of the film samples.
