X-ray spectroscopy is an important tool for scientific analysis. While the earliest
demonstration experiments were realised in the laboratory, with the advent of synchrotron …

The advent of femtosecond lasers has shed new light on non-equilibrium high energy
density physics. The ultrafast energy absorption by electrons and the finite rate of their …

We describe a series of microcalorimeter X-ray spectrometers designed for a broad suite of
measurement applications. The chief advantage of this type of spectrometer is that it can be …

We simulate X-ray absorption spectra at elemental K-edges using time-dependent density
functional theory (TDDFT) in both its conventional linear-response implementation and its …

X-ray emission spectroscopy (XES) is a powerful element-selective tool to analyze the
oxidation states of atoms in complex compounds, determine their electronic configuration …

An analytical model is presented, which allows estimating the expected dose rates resulting
from X-ray emission from ultra-short-pulse laser-produced plasma under industrial …

High harmonic spectra for H 2 and H 2+ are simulated by solving the time-dependent Kohn–
Sham equation in the presence of a strong laser field using an atom-centered Gaussian …

Experimental tools capable of monitoring both atomic and electronic structure on ultrafast
(femtosecond to picosecond) time scales are needed for investigating photophysical …

We report here on the results of comparative experimental measurements of laser energy
absorption in a bulk and different morphology nanowire arrays interacting with relativistically …

The development of X-ray diffractometry at the turn of the 21st century is presented. The
review covers instrumentation development for structural studies based on the use of both …
