Center for X-rays in Swedish Materials Science (CeXS)

CeXS is the academic host of the Swedish Material Science beamline at PETRA III, DESY in Hamburg.

Focusing on enhancing the use of high energy X-rays for materials R&D, CeXS is:

1. Securing Sweden's privileged access to PETRA III

2. Engaging researchers to use the opportunities

3. Educating and disseminating results

CeXS is currently orchastrating instrument proposals, for the future PETRA IV, which can give new insights into material science. Read more here about how you can support and get engaged in this key issue for the Swedish material science community!

Apply for privileged access

Be at the cutting edge

Cutting edge innovation now requires advanced materials characterisation, for example, non-destructive characterisation within materials at high temporal resolution – entailing the use of high energy X-rays facilities such as PETRA III.

Fundamental Research

Water is crucial to our planet and lives – yet is still a scientific mystery.

This mystery is being unravelled with high-energy X-ray experiments at PETRA III.

Researchers at Stockholm University have discovered liquid water has two phases. These two phases have large differences in structure and density at low temperatures.

Engineering research

We’ve know that in offshore applications hydrogen embrittles stainless steels - but not why.

KTH and Sandvik researchers used time resolved measurements and found that the two phases of duplex stainless steel each react to hydrogen in different ways: H is more likely to diffuse through the bcc phase and dissolve in the fcc phase - so increased internal stresses, and thereby embrittlement, is inevitable.
