Abstract

The 14 beamlines currently in operation at the Laboratório Nacional de Luz Síncrotron (LNLS, National Synchrotron Light Laboratory) make it the largest multiuser laboratory in Brazil. Most of the projects carried out at the LNLS can be classified as being in the area of “materials science”, which, in its broadest sense, encompasses fields as wide-ranging as condensed matter physics, structural chemistry, materials engineering, pharmacology, and dentistry. This FAPESP Multi-User Equipment Program proposal represents, in a coordinated manner, the concerns of a large portion of the users of the beamlines employed for X-ray diffraction (lines XPD, XRD-1 and XRD-2), X-ray absorption (lines XAFS-1, SAFS-2 and DXAS) and SAXS (lines SAXS-1 and SAXS-2). In 2008, 352 proposals were submitted for the use of these lines. Of those, 276 were carried out, resulting in 141 published articles. Users from within the state of São Paulo accounted for 46% of the total. The superconducting wiggler installed in 2009 will produce X-rays that are 1,000 times more intense than are those of the abovementioned lines. This technology will be employed in a new, state-of-the-art, multipurpose beamline (for X-ray diffraction, X-ray absorption, and small-angle X-ray scattering) that will be dedicated to materials science. It is crucial that modern equipment be installed at the LNLS experimental station, which needs a state-of-the-art detector array, as well as a magnet/cryostat for the sample environment and a set of Be focusing lenses. In addition, we are requesting the acquisition of special diffractometers that will confer greater versatility and efficiency on the current diffraction beamlines at the LNLS. The approval of this proposal in its entirety and the subsequent combined use of the equipment requested will raise the LNLS to the level of a world-class facility for the advanced characterization of materials. This is true not only for the original laboratory (LNLS-1) but also for its sister laboratory (LNLS-2), soon to be constructed. There are 11 associated projects and 88 complementary projects linked to this proposal. Of those 99 projects, 24 are funded by FAPESP, which has, to date, invested a total of R$ 13 million. All of the researchers involved in these projects currently use the LNLS facilities to conduct at least part of the research related to their projects, indicating the relevance of the present proposal for scientific production in the state of São Paulo.
