Optical layout of the FEL-1 beamline at S3FEL. M1 and M2 form the primary offset mirror group. M3 and G, M4 and M5c are configured for monochromatic and ultrafast endstations, with switchable functionality. M6 serves as a deflecting mirror for FEL beam switching. KB mirror systems at each end station allow for micro-focusing. |
