A multi-cone x-ray imaging Bragg crystal spectrometer.

This article describes a new x-ray imaging Bragg crystal spectrometer, which-in combination with a streak camera or a gated strip detector-can be used for time-resolved measurements of x-ray line spectra at the National Ignition Facility and other high power laser facilities. The main advantage of this instrument is that it produces perfect images of a point source for each wavelength in a sele...

The NEAR X-Ray/Gamma-Ray Spectrometer

he X-Ray/Gamma-Ray Spectrometer on the Near Earth Asteroid Rendezvous (NEAR) spacecraft will remotely sense X-ray and gamma-ray emissions from the surface of near-Earth asteroid 433 Eros and look for characteristic “signatures” in those emissions to determine its elemental composition. During the planned 10 months of orbits about Eros beginning in early 1999, data returned from the instrument w...

X-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...

X-Ray, Crystal Structure and Solution Phase Studies of a Polymeric SrII Compound

In the crystal structure of the title polymeric compound, [C42H38N6O33Sr5.2(H2O)]n, five independent metal atoms (Sr1-Sr5) have different coordination environments. The Sr1 and Sr5 atoms are nine coordinated and feature distorted tricapped trigonal-prismatic and capped square-antiprismatic geometries, respectively....

Development of a Crystal Spectrometer for Low-energy X-ray Measurements

He-like heavy ions are the simplest atomic multibody systems. They are in particular well suited to study electron-electron effects in the presence of strong Coulomb fields where QED contributions are of considerable importance. Recent progress in the spectroscopy of these ions [1] and in related theoretical investigations [2] opened new perspectives for such studies up to He-like uranium. A fu...
