“…(b) Normalized, azimuthally averaged intensity I(q) of the signal for both detectors as shown in (a). 25,27 A stack of aberration-corrected, nano-focus compound refractive lenses (CRLs) [28][29][30] was used to focus the XFEL beam to a diffraction-limited focal spot 31,32 of 94 nm (FWHM). In the NFH configuration (Fig.…”

Structural dynamics of water in a supersonic shockwave

We explore the pressure evolution and structural dynamics of transient phase transitions in a microfluidic water jet after a laser-induced dielectric breakdown. To this end, we use a combined approach of nearfield holography with single femtosecond X-ray free-electron laser pulses and X-ray diffraction. We observe chaotic perturbations with thin filamentation during the gas expansion after dielectric breakdown, and shockwave emission along the jet. The formation of the shockwave is accompanied by pronounced changes in the structure factor, indicating a transition to a high density liquid phase induced by the transient pressure rise.

“…In the field of X-ray optics, refractive lenses (CRLs) and multilayer Laue lenses (MLLs) [49] are intensively developed at DESY. MMLs in particular can generate single-digit nanometre foci [50] and reach, at least in principle, a focal spot size of one nanometre [51,52].…”

PETRA III at DESY is one of the brightest synchrotron radiation sources worldwide. It serves a broad international multidisciplinary user community from academia to industry at currently 25 specialised beamlines. With a storage-ring energy of 6 GeV, it provides mainly hard to high-energy X-rays for versatile experiments in a very broad range of scientific fields. It is ideally suited for an upgrade to the ultra-low emittance source PETRA IV, owing to its large circumference of 2304 m. With a targeted storage ring emittance of $$20 \times 5\,\textrm{pm}^{2}\,\textrm{rad}^{2},$$ 20 × 5 pm 2 rad 2 , PETRA IV will reach spectral brightnesses two to three orders of magnitude higher than today. The unique beam parameters will make PETRA IV the ultimate in situ 3D microscope for biological, chemical, and physical processes helping to address key questions in health, energy, mobility, information technology, and earth and environment.

“…This however, also reduces their efficiency. Furthermore, CRLs have strong chromatic aberrations so their ability to focus to extremely small spot sizes is limited [13]. Reflective mirrors, such as Kirkpatrick-Baez (KB) mirrors, which operate at grazing incidence, can accept the full beam.…”
