Elettra, one of the first third generation synchrotron radiation sources implemented in Europe, was upgraded with a new full-energy injector and since five years routinely operates in top-up mode both at 2.0 and 2.4 GeV, with increased source stability and availability (over 97% of the scheduled beamtime). This makes Elettra one of the only two sources that were not originally designed with...

The XAFS beamline at Elettra is dedicated to x-ray absorption spectroscopy (XAS). It is a standard energy scanning XAS beamline built on a bending magnet x-ray source. It is designed to cover a large energy range: from 2.4 to 27 keV. The XAFS beamline aims to meet the needs of researchers in the area of conventional XAS. It is therefore conceived to be general purpose and open to a very wide...

A growing number of transparent conducting oxides (TCO’s) combining transparency for visible light with good electrical conductivity has been found and studied. The carrier concentration can be varied in some cases making them either more semiconducting- or metal- like. The preferential doping is n-type while p-type is hard to achieve and only some attempts have been reported. No consensus on...

Most of the hard X-ray beamlines at the synchrotron radiation facilities require a crystal monochromator to select a particular range of the energy with a high value of the resolution. This job must be performed without degrading the quality of the beam that is characterized by the flux, brilliance and the resolution.
One of the most important sources of the degradation is thermo-mechanical...

Solid-state scintillation detectors are widely used in modern multi-slice CT systems as well as synchrotron micro-tomography beamlines. Amongst other parameters, the performance of these detectors depends on the thickness of the scintillator. Thicker scintillators result in higher emission intensities, yet the resolution deteriorates as the thickness increases. To achieve a higher scan speed,...
