Preliminary Design Development of ITER X-ray Survey Spectrometer

ITER Core Imaging X - Ray Spectrometer

During Phase 2 of our study of the CIXS conceptual design we have tackled additional important issues that are unique to the ITER environment. These include the thermal control of the crystal and detector enclosures located in an environment with a 100°–250° C ambient temperature, tritium containment, and the range of crystal and detector movement based on the need for spectral adjustments and ...

Reducing the Size of the Borehole X-ray Fluorescence Spectrometer (XRFS) Probe: Preliminary Design Study

Development of the hard-X-ray angle resolved X-ray photoemission spectrometer for laboratory use.

This article reports development of a practical laboratory hard X-ray photoelectron spectroscopy (HXPS) system by combining a focused monochromatic Cr K(alpha) X-ray source, a wide angle acceptance objective lens and a high kinetic energy electron analyzer. The Cr K(alpha) source consists of a Cr target, a 15 kV focused electron gun, and a compact bent crystal monochromator. The X-ray spot size...

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...
