TL;DR: JEEP is a high-energy (50–150 keV) multi-purpose beamline offering polychromatic and monochromatic modes, enabling in situ studies using radiography, tomography, energy-dispersive diffraction, monochROMatic and white-beam two-dimensional diffraction/scattering and small-angle X-ray scattering.

TL;DR: In this paper, an internal short circuiting device was used for controlled, on-demand, initiation of thermal runaway in lithium-ion batteries, allowing analysis of the nucleation and propagation of failure within 18 650 cells through the use of high-speed X-ray imaging at 2000 frames per second.

TL;DR: For the first time, the mechanisms that lead to the most catastrophic type of cell failure, rupture, and explosion are identified and elucidated in detail and are expected to guide the development of safer commercial cell designs.

TL;DR: This work proposes an alternative technique which is based on the Fourier analysis of the sinogram which shows excellent performance particularly on challenging data.

TL;DR: Three techniques for tackling severe ring artifacts in reconstructed images of synchrotron-based X-ray micro-tomography systems are proposed, which are easy to implement; do not generate extra stripe artifacts and void-center artifacts; and give superior quality on challenging data sets and in comparison with other techniques.
