Technical details

The beamline is capable of offering fast switching circular and linear polarisation from helical undulator devices from 2 to 15 keV. As such, it provides a unique source to the scientific community. The suite of experimental stations including sample environment (high magnetic fields and low temperature control) and detection schemes that make it possible to retrieve all information from X-ray absorption spectroscopy and to reliably measure dichroic effects as small as 10^-5.
