Grazing-Exit X-ray Analysis
are needed. Since the analysis depth depends on the accelerating voltage of the electron beam, the application of low accelerating voltages limits the characteristic-X-ray generation region to a minute region near the specimen surface. However, the energies of the X-rays are less than those of the accelerated electrons; this causes a new problem: the use of analytical X-ray lines is limited. Th...
متن کاملX-ray Absorption Spectroscopy Using X–ray Fluorescence Spectrometer
Strong characteristic Kα X-ray lines are accompanied by weak lines due to the radiative Auger effect (RAE) [1, 2]. The characteristic Kα fluorescent X-rays (K-L2,3 lines) are emitted by the 2p→1s electric dipole transition after one of the 1s electron photoionization, Though the probability is less than 0.01, one of the 2p electrons is excited into an unoccupied discrete or continuum level simu...
متن کاملGrazing-exit and micro X-ray fluorescence analyses for chemical microchips.
Grazing-exit x-ray fluorescence (GE-XRF) and micro x-ray fluorescence (micro-XRF) methods were applied to chemical microchips as a detection method. Since an energy-dispersive x-ray detector was used, the simultaneous detection of multiple elements was possible. An analyzing region was especially designed on the microchip so that a sample solution could be dried and concentrated in a suitable a...
متن کاملMicro X-ray Fluorescence Spectrometer for Light Element Analysis with Low Power Tube Excitation
This system consists of an air cooled low power x-ray tube (50W) with molybdenum anode and a thin (70μm) exit window. An optional beam filter can be inserted to reduce spectral background. The beam is focused onto the sample using a polycapillary x-ray optics, offering a focal spot of about 30μm FWHM. Characteristic X-rays from the sample are detected by means of a Si(Li) detector with ultra th...
متن کاملDepth profiling of low energy ion implantations in Si and Ge by means of micro-focused grazing emission X-ray fluorescence and grazing incidence X-ray fluorescence
Depth-profiling measurements by means of synchrotron radiation based grazing XRF techniques, i.e., grazing emission X-ray fluorescence (GEXRF) and grazing incidence X-ray fluorescence (GIXRF), present a promising approach for the non-destructive, sub-nanometer scale precision characterization of ultra shallow ion-implantations. The nanometer resolution is of importance with respect to actual se...
