Surface X-ray diffraction experiments at SOLEIL

Lindsay and Harald were at the SOLEIL synchrotron last week to perform measurements at the beamline SixS. They used X-rays to study the surface structure of an alloy of platinum with tin. The experiment was part of a collaboration with Lund University and the University of Bremen.

The X-ray diffraction instrument at SixS used to study surfaces in ultra-high vacuum.
The sample being heat-treated in the vacuum chamber. It’s the red-orange disc in the middle of the rectangular yellow-orange plate.
Surface X-ray diffraction signal. The vertical streak is called a ’rod’, and is characteristic for X-ray scattering from two-dimensional structures.
