Airbox housing of the Jungfrau Detector for in Vacuum X-ray Diagnostics

At the European XFEL facility, ultrabright X-ray radiation is employed to investigate phenomena in a variety of sample materials with the highest spatial and temporal resolution. For X-ray detection, the scientific ‘Jungfrau’ detector is frequently employed, as it matches the parameters of the provided X-ray beams. Originally developed by the Paul Scherrer Institute for in-air use at the Swiss FEL, a detector housing has been designed and constructed at European XFEL to meet the requirements of in-vacuum operation at the scientific instruments for high-energy density physics (HED) and material-induced dynamics (MID) . The in-vacuum version of the Jungfrau detector is applied in various specialized diagnostics and methods aimed at resolving atomic lattice structures through X-ray diffraction, observing laser-induced microscopic material changes such as shock-wave dynamics via X-ray imaging and small-angle X-ray scattering, or probing plasma temperatures with inelastic X-ray spectroscopy. To exploit the coherence of the X-rays, the design includes a windowless X-ray photon beam path extending from the source to the sample and detector plane. This contribution presents the housing design for a single module and showcases fully integrated solutions for selected X-ray diagnostics, incorporating multiple modules to enhance functionality. selected x-ray diagnostics.
