Abstract: In experiments preliminary to the design of an x-ray excited optical luminescence (XEOL) based chemical mapping tool we have used x-ray micro (4.5 „¿m „ªƒn5.2 „¿m) and macro (1 mm „ªƒn6 mm) beams with similar total fluxes to assess the effects of a high flux density beam of xrays at energies close to an absorption edge on inorganic surfaces in air. The near surface composition of corroded cupreous alloys was analysed using parallel x-ray and optical photoemission channels to collect x-ray absorption near-edge structure (XANES) data at the Cu-K edge.
