4D reconstruction of alumina laser melt pools at 25 kHz via operando X-ray multi-projection imaging

Lars Witte, Eliot Jermann, Zhe Hu +9

Advancing additive manufacturing, e.g., laser powder-bed fusion (LPBF), requires resolving rapid processes such as melt-pool dynamics and keyhole evolution in 4D (3D + time). Opera…

4D Synchrotron X-Ray Multi Projection Imaging (XMPI) for studying multiphase flow dynamics and flow instabilities in porous networks

Patrick Wegele, Zisheng Yao, Jonas Tejbo +11

Flow instabilities such as Haines jumps in porous media are common phenomena that occur on sub-second timescales. X-rays are particularly suitable for investigating these processes…

Time-resolved X-ray radiography of through-thickness liquid transport in partly saturated needle-punched nonwovens

Patrick Wegele, Zisheng Yao, Jonas Tejbo +7

Nonwoven fibre networks underpin filtration, insulation and geotextiles, where liquid uptake, redistribution and release govern performance. In needle-punched felts, barbed needles…

Synchrotron X-Ray Multi-Projection Imaging (XMPI) for High-Resolution 4D Characterization of Multiphase Flows

Tomas Rosén, Zisheng Yao, Jonas Tejbo +15

Multiphase flows where particles, bubbles, or droplets are suspended in a fluid govern critical processes in biology, medicine, materials processing, and geophysics. However, obser…

Time-resolved 3D imaging opportunities with XMPI at ForMAX

Julia Katharina Rogalinski, Zisheng Yao, Yuhe Zhang +11

X-rays are commonly used in imaging experiments due to their penetration power, which enables non-destructive resolution of internal structures in samples that are opaque to visibl…

Search for low-mass dijet resonances using trigger-level jets with the ATLAS detector in collisions at TeV

ATLAS Collaboration

Searches for dijet resonances with sub-TeV masses using the ATLAS detector at the Large Hadron Collider can be statistically limited by the bandwidth available to inclusive single-…
