Alvra Experimental Station

The Alvra group operates, maintains, and further develops the Alvra Experimental Station at SwissFEL. Alongside their own research, they support and collaborate with researchers who have been granted beamtime through the SwissFEL peer-review process. 


The combined skill set of the group enables a diverse range of experiments to be supported at the Alvra Experimental Station. Here, scientists can examine the ultrafast dynamics of photochemical and photobiological systems using a variety of X-ray scattering and spectroscopic techniques.
