TL;DR: In this article, a series of transition lines and their intensities have been analyzed and compared with collisional-radiative simulations, which reproduce well the relative line intensities and facilitate line identification of ions produced in the EBIT.

TL;DR: This paper describes how the distribution of average phase tilts and intensities on hard x-ray pulses with peak intensities of 10(21) W/m(2) can be retrieved from an ensemble of diffraction patterns produced by 70 nm-radius polystyrene spheres, in a manner that mimics wavefront sensors.

TL;DR: This technique opens the door to femtosecond diffractive imaging of a wide range of micrometer-sized materials that exhibit irreproducible complexity down to the nanoscale, including airborne particulate matter, small cells, bacteria and gold-labeled biological samples.

TL;DR: In this paper, the authors measured the extreme-ultraviolet spectra of intermediately ionized iron ions (Fe VI-Fe XIV) in the wavelength range of 125.0-265.0 A at the Heidelberg electron beam ion trap.

TL;DR: A de novo phase retrieval technique is demonstrated by encapsulating an object in a superfluid helium nanodroplet, which provides both a physical support and an approximate scattering phase for the iterative image reconstruction.
