Privileged or paid access?
Access to synchrotron beam lines at PETRAIII, DESY is open to Swedish universities, research organisations and companies. The process for gaining access depends upon whether you wish to publish the results from the measurements, or keep these entirely confidential.
If you’re happy to publish measurement results in scientific articles, then you can apply for privileged access by submitting a beam time proposal. The beam time application and review process is described on this CeXS homepage
If you need to keep your results entirely confidential, then you need to pay for beam time access. For some advice about what to think about, and information about where to get support, see this CeXS webpage.
