  The European-XFEL, a 3.3 km long X-Ray laser facility, powered by a 17.5 GeV superconducting linear accelerator, is located at DESY in Hamburg [1]. For the diagnostics ultra-high vacuum components with high mechanical precision and strict requirements on particle cleanliness had to be developed, designed and produced. For the screen system of the facility, enabling to observe the size and shape of the electron beam, massive vessels, precisely milled out of stainless steel blocks 1.4435 (316L) have been produced. For these chambers all flange-connections are milled into these blocks. This paper will report onμdamages in these integrated knife edges and will present simulations of the damage mechanisms. It will also describe the influences of material properties of two different stainless steel brands, effects on the ¿knife edge¿ due to the penetration into the gaskets as well as the non-elastic deformation of the sealing area. The dependence of tightening forces under special conditions, like the very clean conditions in particle free applications due to the non-lubricated conditions will be reported. A ¿cooking recipe¿ to avoid suchμdamages will be given.

  From 2013 to 2016 the free electron laser FLASH at DESY in Hamburg, Germany was upgraded with a second undulator line, photon diagnostic line, beam distribution and experimental hall connected to the same linear accelerator. This paper shows the layout of the photon diagnostic section and an overview of the civil engineering challenges. The mechanical design of selected components, e.g. vacuum components, diagnostic equipment and safety related components is presented.

We present the final engineering design and first commissioning results of two highly integrated experimental stations for the micro-focusing (FMX) and the highly automated (AMX) MX beamlines at the NSLS-II. These beamlines will support a broad range of biomedical structure determination methods. The experimental stations are designed and fabricated in-house to meet the challenging requirements resulting from the small beam size of 1 µm and the extremely short working distance of only 190 mm from the beam exit window to the FMX focal spot. The compact beam conditioning unit contains, within 140 mm, a beam position monitor, an attenuator, primary slits, an intensity monitor, a sub-millisecond shutter, and secondary slits. The diffractometers consist of an interchangeable dual axis air bearing-based goniometers with a target sphere of confusion of 100 nm, an on-axis microscope, an x-ray fluorescence detector and dynamic beam shaping slits. The end stations are integrated in a compact space on a granite machine bed with high modularity for future upgrades and extensions. Real-time autonomous robotic systems are being implemented for high through-put cryogenic sample handling.
