The 21st edition of the International Congress on X-Ray Optics and Microanalysis (ICXOM) will be held in Campinas-SP, Brazil, from 5th to 8th September 2011, at The Brazilian Synchrotron Light Laboratory (LNLS). For the first time a congress of this series will be held in a Latin-American country. Moreover the meeting itself will be a great opportunity to know the currently status of the new 3.0 GeV 3rd generation of LNLS, an innovative project underway to construct one of the brightest synchrotron machines in the world. The 21st International Congress on X-ray Optics and Microanalysis (ICXOM21) is dedicated to bring together scientists and technologists involved in fundamental and applied research in the field of micro (nano) analysis by means of X-ray beams, with emphasis on synchrotron sources, electrons and other energetic particle, or active in methodology and instrumental developments. The ICXOM21 target audience is both for people already involved in these fields, as well as newcomers. Presentations of new scientific results from scientists involved in fundamental and applied research from these fields or active in methodological and instrumental developments will be made by invited and contributing speakers, demonstrating recent progress. The conference program provides an excellent opportunity for researchers, students, scientists and technologists to share a common place for fruitful discussions, present new or state-of-art results within the conference topics, exchange information with experts already involved in these areas, as well as to establish or renew direct contacts with colleagues during the social program, poster program or at the industrial presentation. The ICXOM21 is organized by the Brazilian Synchrotron Light Laboratory (LNLS) and National Laboratory of Biosciences (LNBio), both operated by The Brazilian Association for Synchrotron Light Technology (ABTLuS) for the Brazilian Ministry of Science and Technology (MCT).
