A new compact setup for in-situ grazing incidence X-ray experiments of solid and liquid samples

Abstract

Abstract A compact new X-ray reflectometer setup was realized, with a main design focus on mechanical stability and ruggedness, allowing in particular the change from a horizontal to a vertical scattering geometry, this way enabling polarization dependent experiments, and an easy transfer from one beamline to another. An additional mirror system was established, that allows to deflect the beam downwards to also render investigations of liquid sample surfaces possible. The layout of the reflectometer setup is described, and some representative grazing incidence EXAFS measurements outlining the experimental capabilities of the system are presented.
