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-…
