• Abstract

  In this project, we propose a set of experiments which are not possible in Brasil today, in particular, at the National Laboratory of Synchrotron Light (LNLS). The experiments include the electronic and structural properties of surface alloys and oxides important. for catalysis; the electronic properties of complex molecules in different environments; and the magnetic properties of colloi…

• Abstract

  We describe a master's degree proposal linked to the Sirius project to be run with the co-guidance of Dr. Liu Lin, leader of the group that designed Sirius. In order to obtain the required precision of 40 micrometers to determine the center of the quadrupole and sextupoles of the ring, we propose an application of the Beam Based Alignment method that uses the electron beam itself to make …

• Abstract

  We are concerned with the description of imaging experiments using light scattering from a single femtosecond X-ray laser pulse incident on a single nanocrystal (or set of a few single nanocrystals). Following our successful discussion and application of the scalar scattering model for arbitrary tenuous scatterers, we want to explore vector models for situations of non-uniform non-tenuous…
