Abstract

In the past few years, the development of light sources of the 4th generation, namely XUV/X-ray Free Electron Lasers provides to the scientific community outstanding tools to investigate matter under extreme conditions never obtained in laboratories so far. As theory is at its infancy, the analysis of matter via the self-emission of the target is of central importance. The characterization of such dense matter is possible if photons can escape the medium. As the absorption of K-shell X-ray transitions is minimal, it plays a key role in this study. We report here the first successful observation of K-shell emission of Nitrogen at 430 eV using an XUV-Free Electron Laser to irradiate solid Boron Nitride targets under exceptional conditions: photon energy of 92 eV, pulse duration of ∼20 fs, micro focusing leading to intensities larger than 1016 W/cm2. Using a Bragg crystal of THM coupled to a CCD, we resolved K-shell line emission from different charge states. We demonstrate that the spectroscopic data allow characterization of electron heating processes when X-ray radiation is interacting with solid matter. As energy transport is non-trivial because the light source is monochromatic, these results have an important impact on the theory. © 2011 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim.

Abstract

The beam of the Free-Electron Laser in Hamburg (FLASH) was focused by a grazing incidence elliptical mirror (32.5 nm and 13.5 nm) and an off-axis parabolic mirror coated with a Si/Mo multilayer (13.5 nm) to 20-micron and 1-micron spot, respectively. The grazing incidence and normal incidence focusing of ∼25-fs pulses with an energy of 10 μJ resulted in an irradiance of 10 13 W/cm 2 and 10 16 W/cm 2 , respectively, at the surface of various solids (Si, Al, Ti, Ta, Si 3 N 4 , BN, a-C/Si, Ni/Si, Cr/Si, Rh/Si, Ce:YAC, poly(methyl methacrylate) ― PMMA, stainless steel, etc.). The optical emission of the plasmas produced under these conditions was registered by a grating (1200 lines/mm and/or 150 lines/mm) spectrometer MS257 (Oriel) equipped with iCCD head (iStar 720, Andor). Surprisingly, only lines belonging to the neutral atoms were observed at intensities around 10 13 W/cm 2 . No spectral lines of ions have been identified in UV-vis spectra emitted from the plasmas formed by the FLASH beam focused in a 20-micron spot. At intensities around 10 16 W/cm 2 , the OE spectra are again dominated by the atomic lines. However, a weak emission of Al + and Al 2+ was registered as well. The abundance ratio of Al/Al + should be at least 100. The plasma has an excitation temperature equivalent to 0.8 eV found by a computer simulation of the aluminum plasma OE spectrum. A broadband emission was also registered, both from the single-element plasmas (typical is for carbon; there were no spectral lines) and the scintillating slabs (on Ce:YAG crystal, both the luminescence bands and the line plasma emission were recorded by the spectrometer).
