Positioning the Vacuum Chamber for X-ray Diffraction Experiments

PI-Vacuum-Chamber-PI-Hexapod
Here, the PI Hexapod carries a UHV chamber for crystallographic experiments in high-energy X-rays (Image: Beamline I811, MAXlab, Lund, Sweden, UHV chamber: Dr. J. Alvarez, Universidad Autonoma de Madrid, Spain)

At Sweden’s MAXlab, at storage ring MAX II, Beamline I811 is dedicated to materials science research with X-ray absorption spectroscopy and surface science dedicated X-ray diffraction experiments.

For surface, interface, thin film and general X-ray scattering experiments a multipurpose diffractometer is available. Mounted on the diffractometer, an H-850 (formerly M-850) standard Hexapod is used to align the vacuum chamber with the sample in the beam. With its six degrees of freedom, it positions a chamber of 20 to 50 kg with a repeatability of below 1 μm in any orientation.
