Description
The European XFEL comprises three SASE beamlines that branch to eight endstation instruments. Each beamline currently operates a single instrument exclusively, fundamentally limiting the total beamtime available for experiments. In this talk, we propose an electron beam steering approach that can enable simultaneous operation of multiple scientific endstations on a single undulator beamline. By avoiding the thermal and mechanical limitations of X-ray optical multiplexing, our method allows flexible beam distribution between instruments at up to MHz repetition rates.
We describe the implementation of fast beam steering at the European XFEL, characterise the joint electron–photon beam response to fast steering, and specify key optical constraints. Finally, we show how our method can be coupled with advanced experimental schemes to unlock new scientific opportunities and evaluate the potential impact of our approach on the design of existing and emerging XFELs beamlines.
