X-ray spectroscopy is a powerful tool for diagnosing the emission characteristics of x-ray sources. It may also be used in characterizing the elemental and chemical states present in compound materials, including the spatial distribution of these states. This presentation will describe the appropriate spectroscopic techniques along with examples of their use. The possibility of using...

Introduced in the late 1990s, laser frequency combs have revolutionized precise measurements of frequency and time. The regular pulse train of a mode-locked femtosecond laser can give rise to a regular comb spectrum of millions of laser modes with a spacing precisely equal to the pulse repetition frequency. Optical frequency combs have enabled the development of new ultra-precise optical...

The application of laser-based techniques as analytical tools in materials science is widespread and very promising by now, also due to the continuous development of the laser technology.
In particular, the Laser Induced Fluorescence (LIF) technique is a molecular spectroscopy based on the interaction of the ultraviolet radiation emitted by a laser with the matter. This technique, for a...

Multilayer coatings are key elements in the extreme ultraviolet spectral range due to the fact that they provide significant reflectance in normal incidence optical configurations. Since their working principle is based on an interferential effect, they perform only in a limited spectral range, therefore having also filtering properties. For this reason they are largely used in imaging...

The ESA Planck satellite, launched on May 14th, 2009, is the third generation space mission dedicated to the measurement of the Cosmic Microwave Background (CMB), the first light in the Universe. Planck observes the full sky in nine frequency bands from 30 to 857 GHz and is designed to measure the CMB anisotropies with an unprecedented combination of sensitivity, angular resolution and control...

Tritium retention on plasma facing components (PFCs) of tokamak vacuum chamber is seen as a serious problem for a secure operation of modern nuclear fusion installations. Tritium surface cartography with tritium overall content determination is required for consecutive detritiation of PFCs. To achieve this goal, one may apply the spectroscopic analysis of the plasma produced by laser ablation...

The Gas Pixel Detector, recently developed and continuously improved by Pisa INFN in collaboration with IASF-Roma of INAF, can visualize the tracks produced within a low Z gas by photoelectrons of few keV. By reconstructing the impact point and the original direction of the photoelectrons, the GPD can measure the linear polarization of X-rays, while preserving the information on the absorption...

The past years have seen the birth of precision spectroscopy in astrophysics. Outstanding scientific questions can be tackled with this technique. Possible slow variations of fundamental constants, such as the fine structure constant or the electron-proton mass ratio, may be detected or limited in magnitude by observing fine structure multiplets in gas clouds and comparison with current...
