Coherent Properties of FELs

  A tutorial on coherence is presented. The question is asked “what is coherence, how do you get it, and what can you do with it?” Common examples of coherence and expectations are discussed with examples from marching bands to global interactions. A TEM visible light laser is separated into its component parts, and then reconstructed, to better understand the emergence of spatial and temporal coherence from noise. Coherent clapping at a football match serves as an introduction to the emergence of coherence in a SASE EUV/x-ray FEL. Young’s double slit (pinhole) technique is used to illustrate interference and phase coherence with applications to undulator radiation, spatially filtered undulator radiation, SASE FELs, and seeded FELs. A few examples are cited.

FEL Beamline Design and Experimental Methods

  I will cover a brief overview of the optical components that will be installed at SwissFEL and why they have been chosen from an experimental perspective. I will then explain some of the various experimental techniques that have been used at XFELs, with experimental examples from both LCLS and SACLA. I will conclude with a discussion on where we think the field of XFEL experiments will be in 3 years, and how SwissFEL plans to fit into this landscape.
