Soft X-Ray Exit Slits for SASE3 beamline
An exit slit is a device installed at a soft X-ray beamline to select monochromatic light behind a dispersive grating. The scope of work consists of design, fabrication, testing and delivery of two identical exit slits for two soft X-ray beamlines at the European XFEL.
Two 120 mm long, wedged and water-cooled boron-carbide blades define the slit aperture. European XFEL will provide the boron-carbide parts according to the blade design developed by the vendor. The exit slit shall comply with UHV (better than 10-9mbar) and particle-free (ISO class 5) specifications.
Major challenges of this project are (a) a 2µm blade movement reproducibility and stability (at 20µm opening range) under changing absorbed thermal load (up to 50W per blade) and (b) a large vertical fully open position (>32mm) combined with the 0.5µm resolution of the blade movement when the slit works in the 20µm opening range.
