متن کاملSurface analysis of dental amalgams by X-ray photoelectron spectroscopy and X-ray diffraction.
OBJECTIVES It is important to characterize the surface of dental amalgam in order to understand the process of mercury release from amalgam restorations in the oral cavity. The mercury evaporation occurs not only from the newly made restoration but also from the set material. METHODS The surfaces of four different types of amalgams, which had been well set, were analyzed with X-ray photoelect...
متن کاملNear Edge X-ray Absorption Fine Structure Spectroscopy with X-Ray Free-Electron Lasers
We demonstrate the feasibility of Near Edge X-ray Absorption Fine Structure (NEXAFS) spectroscopy on solids by means of femtosecond soft x-ray pulses from a free-electron laser (FEL). Our experiments, carried out at the Free-Electron Laser at Hamburg (FLASH), used a special sample geometry, spectrographic energy dispersion, single shot position-sensitive detection and a data normalization proce...
متن کاملFemtosecond X-ray magnetic circular dichroism absorption spectroscopy at an X-ray free electron laser.
X-ray magnetic circular dichroism spectroscopy using an X-ray free electron laser is demonstrated with spectra over the Fe L(3,2)-edges. The high brightness of the X-ray free electron laser combined with high accuracy detection of incident and transmitted X-rays enables ultrafast X-ray magnetic circular dichroism studies of unprecedented sensitivity. This new capability is applied to a study of...
متن کاملUltrafast X-ray Absorption Spectroscopy using Laser-Driven Electron X-ray Sources (LEXS)
A laser driven electron x-ray source (LEXS) using a high repetition rate, terawatt laser system is described. The laser system has adopted design features that make it more suitable for the generation of hard x-ray pulses. These features include a simplified pumping scheme to reduce cost and complexity, a λ/4 broadband regenerative amplifier to support high-energy, short optical pulse generatio...
