Abstract / Description of output
The high-precision X-ray diffraction setup for work with 60 Diamond Anvil Cells (DACs) in Interaction Chamber 2 (IC2) of the High Energy Density Instrument of the European XFEL is described. This includes beamline optics, sample positioning and detector systems located in the multipurpose vacuum chamber. Concepts for pump-probe X-ray diffraction experiments in the DAC are described and their implementation demonstrated during the 1st User Community Assisted Commissioning experiment. X-ray heating and diffraction of Bi under pressure, using 20 fs X-ray pulses at 17.8 keV and 2.2 MHz repetition, is illustrated through splitting of diffraction peaks and interpreted employing finite element modeling of the sample chamber in the DAC.
FingerprintDive into the research topics of 'Novel experimental setup for MHz X-ray diffraction in the Diamond Anvil Cell at the High Energy Density (HED) Instrument of the European X-ray Free Electron Laser'. Together they form a unique fingerprint.
